Plaintiff, ORDER

v.

Safeway Incorporated, et al.,

Defendants. Pending before the Court is Defendant Safeway Inc.’s (“Safeway”) motion to exclude the opinions of Plaintiff Nolan Gorney’s expert, Dr. Michael Steingart. (Doc. 32.) For the following reasons, Safeway’s motion is denied. This case arises out of an accident in which Gorney slipped and fell at a Safeway store. Gorney designated Dr. Steingart, an orthopedic surgeon, as an expert. (See Doc. 56 at 5.) Dr. Steingart conducted an independent medical examination and opined that the accident aggravated Gorney’s preexisting condition. (See Doc. 32-1 at 31, 34.) Dr. Steingart also stated that Gorney’s “vascular status had changed from this fall and in all medical probability caused progression of his clot or for the need of treatment.” (Id. at 34.) Safeway designated two experts: Dr. Michael Domer, an orthopedic surgeon, and Dr. David Feuer, a vascular surgeon. (See Doc. 56 at 5–6; Doc. 32-1 at 46.) Dr. Domer also conducted an independent medical examination and opined that “there is no evidence to support any change to [Gorney’s] vascular status” and that, although the “most likely accident-related diagnosis would be myofascial strains to the back,” Gorney had not sustained any permanent impairments and would not require further treatment “for the full resolution of any accident-related complaints from an orthopedic perspective.” (Doc. 32- 1 at 51–52.) Dr. Feuer opined that, although Gorney had a “longstanding preexisting history of” certain vascular issues, “one would be hard pressed to conclude that the recurrent venous ulcer that [he] developed in the weeks following his fall was in any way related to any of the injuries he may have sustained as a result of that fall.” (Id. at 62.) Dr. Feuer issued an addendum to his report after receiving additional medical records and reached similar conclusions. (See id. at 81, 84–85.) Dr. Steingart issued rebuttal reports to Dr. Domer’s and Dr. Feuer’s reports. In his rebuttal to Dr. Domer’s report, Dr. Steingart stated that he could opine on wound management issues—including issues pertaining to the ulcer Gorney developed after his accident—because he had experience treating open wounds in his career, as orthopedic surgeons did so “before there were wound management specialists.” (See id. at 75–76.) In his rebuttal to Dr. Feuer’s report, Dr. Steingart stated that he “treated vascular ulcers and skin contaminated wounds, deep and superficial venous thrombosis, amputations, and limb swelling” in his career. (Id. at 87.) He opined that Gorney’s preexisting “vascular condition and lower back issue” was “made worse” because of the trauma he sustained from the accident and the setting in which the accident occurred. (See id. at 89.) Safeway moved to exclude Dr. Steingart’s opinions. (Doc. 32.) This motion was fully briefed. (See Docs. 33, 35.) The Court held oral argument on Safeway’s motion at the August 26, 2025 Final Pretrial Conference. (See Doc. 55.) In advance of the hearing, the Court requested supplemental briefing from the parties on the effect of the Ninth Circuit’s recent decision in Engilis v. Monsanto Co., ___ F.4th ____, 2025 WL 2315898 (9th Cir. 2025). (See Doc. 49.) The parties submitted the requested briefing, (see Docs. 51, 52), and in Gorney’s brief, he requested a trial continuance and limited discovery to designate Gorney’s treating physician as an expert if the Court granted Safeway’s motion, (Doc. 52 at 5). At a later hearing, the Court informed the parties that it would deny Safeway’s motion and that this order would follow. (See Doc. 57.) Under Rule 702, a “witness who is qualified as an expert . . . may testify in the form of an opinion or otherwise if the proponent demonstrates to the court that it is more likely than not that” (1) the expert’s “specialized knowledge will help the trier of fact to understand the evidence or to determine a fact in issue,” (2) “the testimony is based on sufficient facts or data,” (3) “the testimony is the product of reliable principles and methods,” and (4) “the expert’s opinion reflects a reliable application of the principles and methods to the facts of the case.” Fed. R. Evid. 702. The proponent must “establish the admissibility criteria . . . by a preponderance of the evidence,” and there is “no presumption in favor of admission.” Engilis v. Monsanto Co., ___ F.4th ____, 2025 WL 2315898, at *6 (9th Cir. 2025). These “exacting” requirements, see Weisgram v. Marley Co., 528 U.S. 440, 455 (2000), are imposed in part because “an expert is permitted wide latitude to offer opinions, including those that are not based on firsthand knowledge or observation,” unlike ordinary witnesses. See Daubert v. Merrell Dow Pharms., Inc., 509 U.S. 579, 592 (1993); see also Fed. R. Evid. 703 (allowing an expert to rely on inadmissible facts or data if “experts in the particular field would reasonably rely on” them). As Rule 702 indicates, whether an expert’s testimony meets these requirements and is admissible is determined by a court, not by a jury. See Fed. R. Evid. 702; Daubert, 509 U.S. at 592–93. Moreover, “challenges to an expert’s opinion go to the weight of the evidence only if a court first finds it more likely than not that an expert has a sufficient basis to support an opinion.” Engilis, ___ F.4th ____, 2025 WL 2315898, at *5. A court’s Rule 702 “inquiry . . . [is] a flexible one,” but the focus is on “the evidentiary relevance and reliability—of the principles that underlie a proposed submission,” not on the “conclusions that they generate.” Daubert, 509 U.S. at 594–95; see also Kumho Tire Co. v. Carmichael, 526 U.S. 137, 149 (1999) (holding Daubert’s “general principles apply to [all] expert matters described in Rule 702”). In this manner, courts are the “gatekeeper, not [the] fact finder.” Elosu v. Middlefork Ranch Inc., 26 F.4th 1017, 1020 (9th Cir. 2022) (citation omitted). Courts may not “select between competing versions of the evidence, . . . determine the veracity of the expert’s conclusions at the admissibility stage,” or “evaluate whether [the opinion] is corroborated by other evidence on the record.” Id. at 1026. Safeway argues that Dr. Steingart’s expert opinions must be excluded because (1) he did not review all of Gorney’s relevant medical records, so his opinions are not based on sufficient facts and data or a reliable methodology, (Doc. 32 at 5–8),1 and (2) as an orthopedic surgeon, he is not qualified to rebut Dr. Feuer’s expert opinions on Gorney’s vascular status, (id. at 8–11). The “subject of an expert’s testimony” must be based on “more than subjective belief or unsupported speculation,” but instead on “any body of known facts or . . . any body of ideas inferred from such facts or accepted as truths on good grounds.” Daubert, 509 U.S. at 589–90 (citation omitted). Such knowledge can include “observations based on extensive and specialized experience.” Kumho, 526 U.S. at 156; see also Engilis, ___ F.4th ____, 2025 WL 2315898, at *9 (“[K]nowledge and experience can . . . serve as the requisite facts or data on which [the expert] render[s] an opinion.” (quotation marks omitted)). Medical knowledge in particular “is often uncertain due to the complexity of the human body and the novelty of emerging medical issues,” so physicians “must use their knowledge and experience as a basis for weighing known factors along with the inevitable uncertaintie
