MEMORANDUM OPINION
START, United States District Judge:
I. INTRODUCTION
Plaintiff Kerby Stracco (“Stracco” or “Plaintiff’) appeals from the decision of Defendant Nancy A. Berryhill, the Acting Commissioner of Social Security (“Commissioner” or “Defendant”), denying her application for disability insurance benefits (“DIB”) under Title II of the Social Security Act, 42 U.S.C. §§ 401-434. The Court has jurisdiction pursuant to 42 U.S.C. § 405(g).1 Presently pending before the Court are cross-motions for summary judgment filed by Stracco and the Commissioner.2 (D.I. 16, 17) For the reasons set forth below, the Court will grant Plaintiffs motion to the extent she seeks a remand, will deny Defendant’s motion, and will remand the matter for further proceedings.
II. BACKGROUND
A. Procedural History
Stracco filed her application for DIB on May 15, 2013, alleging disability beginning January 1, 2012, and later amended the onset date to July 9, 2013, due to traumatic brain injury (“TBI”), post-traumatic stress disorder (“PTSD”), bilateral plantar fasci-itis and foot pronation, and bunions. (D.I. 14-6 at 41) The application was denied on July 31, 2013, and upon reconsideration on September 20, 2013. (D.I. 14-3 at 2-9, 21-40) Stracco filed a request for hearing on September 27, 2013. Hearings were held before an Administrative Law Judge (“ALJ”) on February 11, 2014 and August 18,2014. The ALJ issued a decision finding that Stracco was not disabled under the Act. Stracco filed a request for review by the Appeals Council, which was denied on November 20, 2014, and the ALJ’s decision became the final decision of the Commissioner. (D.I. 14-2 at 7-9)
On March 30, 2015, Stracco filed a Complaint seeking judicial review of the ALJ’s September 24, 2014 decision. (D.I. 1) Stracco moved for summary judgment on December 17, 2015, and the Commissioner filed a cross-motion for summary judgment on January 15, 2016. (D.I. 16, 17)

(Id. at 35-38) She had lost consciousness during each event and was unable to provide much information. (Id.) Plaintiff became v'ery frustrated when pressed. (Id.) Medical notes state that there were many inconsistencies in Plaintiffs account, but also that the events could be very unsettling for Stracco to recount. (Id.) A March 7, 2012 medical note states that Plaintiff has a history of multiple TBIs sustained with blast exposures during her 2007-2008 deployment, with the most recent injury a result of incoming rockets that caused Plaintiff to fall down steps, lose consciousness for some time, and bleed from the ears.

1. Plaintiffs Testimony
Plaintiff was 29 years old at the time of the administrative hearings and on the date of the ALJ’s decision. (D.I. 14-2 at 33, 44, 58)7 She is a high school graduate and worked as a unit supply specialist in the United States Army. (D.I. 14-2 at 44, 45, 58) Plaintiff testified that she experienced a TBI in Iraq and that she was hospitalized for sixty days in 2011 for TBI, PTSD, and depression. (Id. at 45, 48-49) She was transferred to the Wounded Warrior Battalion because she could no longer perform her job, and discharged from the Army in 2013. (Id.) Plaintiff attempted to find employment. (Id. at 46) At the time of the first hearing Plaintiff had one child and she was pregnant with her second child at the second hearing. (Id. at 51, 63)
Stracco testified that she does not drivé, but that she and her husband clean and go shopping together. (Id. at 47-48, 59) She also testified that her husband does the cooking, cleaning, and grocery shopping. (Id. at 59-60) When asked about her daily activities, Stracco testified that sometimes she goes but with her husband, she tries to have some time with her son, or she waits for the baby to get up. (Id. at 48, 60) At the first hearing, Stracco testified that she pays someone to help care for her son because she is scared she will do something wrong. (Id, at 52)
Stracco also testified that her memory- is off, she does not really have patience, her thoughts race, she cannot focus to read, she can do simple math with a calculator, and she has difficulty writing because her hands shake. (Id. at 49, 58, 61) She avoids crowds and does not like men and authority figures. (Id. at 50) She has “a lot” of crying spells and flashbacks. (Id.) She also has difficulty sleeping due to anxiety; (Id, at 51, 60) The PTSD causes her to check doors and windows all the time, keep the lights on, and worry that someone will take her son. (Id. at 62) Leaving the house is a “big trigger” for her, especially with traffic. (Id.)
She receives treatment for her condition. (Id. at 63) She had been seeing a psychiatrist since 2012, who prescribed medication, but stopped seeing her because she became pregnant and the medicine caused suicidal thoughts. (Id. 63-64) She saw the psychiatrist infrequently after she moved, about once or twice a month. (Id, at 64)
[315]*3152. Vocational Expert’s Testimony
The ALJ asked the VE to assume -a hypothetical person of Plaintiffs age, education, and work experience, who could perform semi-skilled light work, consisting of simple, routine tasks; and occasional interaction with supervisors, co-workers, and the general public, (Id. at 65) The ALJ further, limited the hypothetical person to occasional simple decision-making and using judgment to make simple work-related decisions, and performing at a non-production pace with no production standards. (Id.) The VE testified that such a person could perform unskilled, light jobs existing in significant numbers in the national economy, including the representative occupations of laundry worker, garment worker, and packer and packaging worker. (Id. at 65-66) When asked to assume .that the limitations in the hypothetical include definitions of marked impairment, extreme impairment, and marked limitations, the ALJ testified that, “based on the definitions [ ] presented, and using those in the accepted definitions, in it [his] opinion no jobs would exist within the residual functional capacity” that Plaintiff could perform. (Id. at 66-67)
E. The ALJ’s Findings
The ALJ concluded that Plaintiffs conditions were not disabling. In reaching this conclusion, the ALJ first considered that the nature and severity of Plaintiffs head injury/TBI, PTSD with inattention and hyperactivity and lumbar spine pain with spasms and lordosis made them severe impairments, but also found that her depression, bipolar disorder and personal disorders diagnoses were inconsistent and did not appear as frequently as PTSD. (Id. at 26) In addition, the ALJ concluded- that Stracco’s weight was a mild impairment, her post-partum depression was temporary, the tinnitus, otalgia, and foot pain did not establish' significant functional limitations, and there was no clinical evidence of hip abnormality. (Id. at 26-27) The ALJ found that although Plaintiffs impairments were subjectively severe, there was insufficient evidence of record to meet the requirements of a listing in 20 C.F.R. Part 404, Subpart P, Appendix 1.
The ALJ determined that Plaintiff retained the residual functional capacity to perform light work,8 except that she is limited to semi-skilled work; understanding, remembering and carrying-out instructions for simple and routine tasks; interacting with supervisors, co-workers, and the general public only occasionally; making simple decisions only occasionally; use of judgment to make simple work related decisions; the ability to perform work that does not require satisfaction of production pace; and the ability to perform work by avoiding production standards or changes generally in judgment. (Id. at 30) The ALJ determined that there was not enough information available to determine whether Plaintiff could perform her past relevant work, but concluded that because there was other work she could perform, he would not delay issuance of the decision to obtain additional vocational information. (Id. at 38) The ALJ concluded [316]*316that Stracco was capable of performing work that exists in significant numbers in the national economy that she can perform, and, therefore, determined that Plaintiff was not disabled from January 1, 2012 through the date of the September 24, 2014 decision. (Id. at 38)
III. LEGAL STANDARDS
A. Motion for Summary Judgment
“The court shall grant summary judgment if the movant shows that there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law.” Fed. R. Civ. P. 56(a). The moving party bears the burden of demonstrating the absence of a genuine issue of material fact. See Matsushita Elec. Indus. Co. v. Zenith Radio Corp., 475 U.S. 574, 586 n.10, 106 S.Ct. 1348, 89 L.Ed.2d 538 (1986). A party asserting that a fact cannot be — or, alternatively, is — genuinely disputed must be supported either by citing to “particular parts of materials in the record, including depositions, documents, electronically stored information, affidavits or declarations, stipulation (including those made for the purposes of the motions only), admissions, interrogatory answers, or other materials,” or by “showing that the materials cited do not establish the absence or presence of a genuine dispute, or that an adverse party cannot produce admissible evidence to support the fact.” Fed. R. Civ. P. 56(c)(1)(A) & (B). If the moving party has carried its burden, the nonmovant must then “come forward with specific facts showing that there is a genuine issue for trial.” Matsushita, 475 U.S. at 587, 106 S.Ct. 1348 (internal quotation marks omitted). The Court will “draw all reasonable inferences in favor of the nonmoving party, and it may not make credibility determinations or weigh the evidence.” Reeves v. Sanderson Plumbing Prods., Inc., 530 U.S. 133, 150, 120 S.Ct. 2097, 147 L.Ed.2d 105 (2000).
To defeat a motion for summary judgment, the non-moving party must “do more than simply show that there is some metaphysical doubt as to the material facts.” Matsushita, 475 U.S. at 586-87, 106 S.Ct. 1348; see also Podobnik v. U.S. Postal Service, 409 F.3d 584, 594 (3d Cir. 2005) (stating party opposing summary judgment “must present more than just bare assertions, conclusory allegations or suspicions to show the existence of a genuine issue”) (internal quotation marks omitted). However, the “mere existence of some alleged factual dispute between the parties will not defeat an otherwise properly supported motion for summary judgment;” a factual dispute is genuine only where “the evidence is such that a reasonable jury could return a verdict for the nonmoving party.” Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 247-48, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986). “If the evidence is merely colorable, or is not significantly probative, summary judgment may be granted.” Id. at 249-50, 106 S.Ct. 2505 (internal citations omitted); see also Celotex Corp. v. Catrett, 477 U.S. 317, 322, 106 S.Ct. 2548, 91 L.Ed.2d 265 (1986) (stating entry of summary judgment is mandated “against a party who fails to make a showing sufficient to establish the existence of an element essential to that party’s case, and on which that party will bear the burden of proof at trial”).
B. Review of the ALJ’s Findings
The Court must uphold the Commissioner’s factual decisions if they are supported by “substantial evidence.” See 42 U.S.C. § 405(g); Monsour Med. Ctr. v. Heckler, 806 F.2d 1185, 1190 (3d Cir. 1986). “Substantial evidence” means less than a preponderance of the evidence but more than a mere scintilla of evidence. See Rutherford v. Barnhart, 399 F.3d 546, 552 (3d Cir. 2005). As the United States Supreme Court has noted, substantial evi[317]*317dence “does not mean a large or significant amount of evidence, but rather such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.” Pierce v. Underwood, 487 U.S. 552, 565, 108 S.Ct. 2541, 101 L.Ed.2d 490 (1988).
In determining whether substantial evidence supports the Commissioner’s findings, the Court may not undertake a de novo review of the Commissioner’s decision and may not re-weigh the evidence of record. See Monsour, 806 F.2d at 1190. The Court’s review is limited to the evidence that was actually presented to the ALJ. See Matthews v. Apfel, 239 F.3d 589, 593-95 (3d Cir. 2001). However, evidence that was not submitted to the ALJ can be considered by the Appeals Council or the District Court as a basis for remanding the matter to the Commissioner for further proceedings, pursuant to the sixth sentence of 42 U.S.C. § 405(g). See Matthews, 239 F.3d at 592. “Credibility determinations are the province of the ALJ and only should be disturbed on review if not supported by substantial evidence.” Gonzalez v. Astrue, 537 F.Supp.2d 644, 657 (D. Del. 2008) (internal quotation marks omitted).
The Third Circuit has explained that: “a single piece of evidence v?ill not satisfy the substantiality .test if the [Commissioner] ignores, or fails to resolve, a conflict created by countervailing evidence. Nor is evidence substantial if it is overwhelmed by other evidence — particularly certain types of evidence (e.g., that offered by treating physicians) — or if it really constitutes not evidence but mere conclusion.” Kent v. Schweiker, 710 F.2d 110, 114 (3d Cir. 1983). Thus, the inquiry is not whether the Court would have made the same determination but, rather, whether the Commissioner’s conclusion was reasonable. See Brown v. Bowen, 845 F.2d 1211, 1213 (3d Cir. 1988). Even if the reviewing Court would have decided the case differently, it must give deference to the ALJ and affirm the Commissioner’s decision if it is supported by substantial evidence. See Monsour, 806 F.2d at 1190-91.
IY. DISCUSSION
A. Disability Determination Process
Title II of the Social Security Act, 42 U.S.C. § 423(a)(1)(D), “provides for the payment of insurance benefits to persons who have contributed to the program and who suffer from a physical or mental disability.” Bowen v. Yuckert, 482 U.S. 137, 140, 107 S.Ct. 2287, 96 L.Ed.2d 119 (1987). For the purposes of DIB, a “disability” is defined as the inability to do any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or which has lasted or can be expected to last for a continuous period of not less than 12 months. See 42 U.S.C. § 423(d)(1)(A). A claimant is disabled “only if his physical or mental impairment or impairments are of such severity that he is not only unable to do his previous work but cannot, considering his age, education, and work .experience, engage in any other kind of substantial gainful work which exists in the national economy.” 42 U.S.C. §. 423(d)(2)(A); see also Barnhart v. Thomas, 540 U.S. 20, 21-22, 124 S.Ct. 376, 157 L.Ed.2d 333 (2003). In determining whether a person is disabled, the Commissioner is required to perform a five-step sequential analysis. See 20 C.F.R. § 404.1520; Plummer v. Apfel, 186 F.3d 422, 427-28 (3d Cir. 1999). If a finding of disability or nondisability can be made at any point in the sequential process, the Commissioner will not review the claim further. See 20 C.F.R. § 404.1520(a)(4).
At step one, the Commissioner must determine whether the claimant is engaged in any substantial gainful activity. See 20 C.F.R. § 404.1520(a) (4)(i) (mandating [318]*318finding of nondisability when claimant is engaged in substantial gainful activity). If the claimant is not engaged in substantial gainful activity, step two requires the Commissioner to determine whether the claimant is suffering from a severe impairment or a combination of impairments that is severe. See 20 C.F.R. § 404.1520(a)(4)(ii) (mandating finding of nondisability when claimant’s impairments are not severe). If the claimant’s impairments are severe, the Commissioner, at step three, compares the claimant’s impairments to a list of impairments that are presumed severe enough- to preclude any gainful work. See 20 C.F.R. § 404.1520(a)(4)(iii); Plummer, 186 F.3d at 428. When a claimant’s impairment or its equivalent matches an impairment in the listing, the claimant is presumed disabled. See 20 C.F.R. § 404.1520(a)(4) (Hi). If a claimant’s impairment, either singly or in combination, fails to meet or medically equal any listing, the analysis continues to steps four - and five. See 20 C.F.R. § 404.1520(e).
At step four, the Commissioner determines whether the claimant retains the residual functional capacity (“RFC”) to perform her past relevant work. See 20 C.F.R. § 404.1520(a)(4)(iv) (stating claimant is not disabled if able to return to past relevant work); Plummer, 186 F.3d at 428. A claimant’s RFC is “that which an individual is still able to do despite the limitations caused by his or her impairment(s).” Fargnoli v. Massanari, 247 F.3d 34, 40 (3d Cir. 2001). “The claimant bears the burden of demonstrating an inability to return to her past relevant work.” Plummer, 186 F.3d at 428.
If the claimant is unable to return to her-past relevant work, step five requires- the Commissioner to determine whether the claimant’s impairments preclude her from adjusting to any other available work. See 20 C.F.R. § 404.1520(g) (mandating finding of non-disability when claimant can adjust to other work); Plummer, 186 F.3d at 428. At this last step, the burden is on the Commissioner to show that the claimant is capable of performing other available work before denying "disability benefits. See Plummer, 186 F.3d at 428. In other words, the Commissioner must prove that “there are other jobs existing in significant numbers in the national economy which the claimant can perform, consistent with her medical impairments, age, education, past work experience, .and [RFC].” Id. In making this determination, the ALJ must analyze the cumulative effect of all of the claimant’s impairments. See id. At this step, the ALJ often seeks the assistance of a VE. See id.
B. The Issues Raised on Appeal
Stracco presents five issues in her appeal and moves for summary judgment on the grounds that the ALJ erred: (1) because his opinions were not based upon factual evidence, he misinterpreted the evidence, and relied upon unproved gossip; (2) in failing to consider the medical .records in their entirety;’ (3) when he misinterpreted the military medical examiners’ records and used the wrong standard in evaluating her PTSD; (4) because he did not give appropriate weight-to her treating physicians; and (5) finding her not entirely credible. The Commissioner moves for summary judgment on the grounds that substantial evidence supports the ALJ’s decision that Plaintiff is not disabled.
C. Evidence Considered
An ALJ is free to choose one medical opinion over another, where the ALJ considers all of .the evidence and gives some reason for discounting the evidence he rejects. See Diaz v. Commissioner of Soc. Sec, 577 F.3d 500, 505-06 (3d Cir. 2009); Plummer, 186 F.3d at 429 (“An [319]*319ALJ ... may afford a treating physician’s opinion more or less weight depending upon the extent to which supporting explanations are provided.”). Opinions of a treating physician are entitled to controlling weight when they are well-supported and not inconsistent with other substantial evidence in the record. See Hall v. Commissioner of Soc. Sec., 218 Fed.Appx. 212, 215 (3d Cir. Feb. 22, 2007) (affirming ALJ’s decision to give little weight to treating physician’s reports because of “internal inconsistencies in various reports and treatment notes ... as well as other contradictory medical evidence”); Fargnoli v. Massanari, 247 F.3d 34, 43 (3d Cir. 2001).
Here, the ALJ detailed his reasons for: (1) affording little weight to the opinion of treating physician Dr. McKee; and (2) affording only some weight to the opinions of Drs." Singer, Surrusco, Chalhoub, Montgomery, Leizer, and the VA disability ratings. (D.I. 14-2 at 35-37) The ALJ also discussed why he assigned little weight to the third-party function report completed by Plaintiffs spouse. (Id. at 37)
The ALJ discussed much of the medical evidence in detail. However, as Strac-co points out, the ALJ’s decision makes no reference to Dr. Russell and Dr. Joyner, both of whom treated Plaintiff for her mental health issues from February 14, 2012 through February 18, 2014, as discussed earlier in this Memorandum Opinion.9 Although the ALJ may have acceptable reasons "for excluding the medical evidence, the Court cannot discern those reasons from the decision as it currently stands. See Fargnoli, 247 F.3d at 42; Plummer, 186 F.3d at 429; see also Cotter v. Harris, 642 F.2d 700, 706-07 (3d Cir. 1981) (“Because .,, an [ALJ] cannot reject evidence for no reason or for the wrong reason, an explanation from the ALJ of the reason why probative evidence has been rejected is required so that a reviewing court can determine whether the reasons for rejection were improper.”). For this reason, the Court will remand the case for a clear explanation of the ALJ’s reason for his failure to consider the mental health treatment Stracco received from Drs. Russell and Joyner. See Fargnoli, 247 F.3d at 42 (courts should “vacate or remand, a case where such an explanation is not provided”).
In addition, the ALJ assigned either little weight or some, weight to the medical evidence of record, but did not assign substantial weight (nor even discuss the issue) to any of the medical opinions. Hence, the Court cannot discern if. the ALJ improperly substituted his medical opinion for those of the physicians who presented competent medical evidence. This provides another basis for remand. See Plummer, 186 F.3d at 429.
Therefore, the Court finds that the ALJ’s decision is not supported by substantial evidence because, the ALJ failed to .articulate how he evaluated the full record of medical evidence. Remand is appropriate in order to obtain a more comprehensive evaluation.10
V. CONCLUSION
For the foregoing reasons, the Court will vacate the decision of the Commission[320]*320er; (2) remand the case further proceedings; (3) deny Plaintiffs motion for summary judgment (D.I. 16) the extent that she seeks judgment in her favor and grant it the extent that she seeks a remand; and (4) deny the Commissioner’s cross-motion for summary judgment (D.I. 17).
An appropriate Order will be entered.
