Washington Outpatient Surgery Center

What Washington Outpatient Surgery Center does

Washington Outpatient Surgery Center (WOSC) is a physician-owned, multi-specialty ambulatory surgery center located at 2299 Mowry Avenue in Fremont, California, directly across from Washington Hospital. Founded in April 1986 and operated as a California LLC, the center has served the East Bay and broader San Francisco Bay Area for over 39 years, delivering outpatient surgical procedures across ten specialty areas: ENT/Otorhinolaryngology, Gastroenterology, General Surgery, Gynecology, Ophthalmology, Orthopedics and Sports Medicine, Pain Management, Plastic Surgery, Podiatry, and Urology. The facility comprises five state-of-the-art operating rooms, a dedicated Endoscopy Center, and an Overnight Recovery Unit with six private suites supported by registered nurses, enabling same-day discharge as well as 23-hour observation cases.

WOSC holds AAAHC accreditation continuously since 1991, re-affirmed in May 2026, and operates as a Medicare-certified ambulatory surgery center with HIPAA-compliant patient information handling. The technology stack includes the THINK TMINI compact robotic system for total knee replacement, introduced in 2025, alongside conventional minimally invasive surgical instrumentation. Medical leadership is provided by a Board President/Medical Director and specialty Medical Directors in plastic surgery, orthopedics, urology, gastroenterology, and anesthesiology, several of whom hold academic appointments and external hospital roles at Washington Hospital Healthcare System.

Revenue is generated through two streams: ambulatory surgical facility fees billed to insurance carriers, Medicare, and patients, and separate physician professional fees. The go-to-market is primarily sales-led and referral-driven, anchored on physician relationships, several of whom hold ownership interests in the center, and reinforced by proximity and integration with Washington Hospital's MyChart and physician-finder systems. The center also maintains an informational website, a Google Business presence, and published patient testimonials as secondary acquisition channels. No app, API, or external integration platform is offered, and no parent company, subsidiaries, funding rounds, or M&A activity are disclosed.

Direct peers

• Surgery Partners: Publicly traded multi-specialty ambulatory surgical center operator with a national footprint. Direct peer to WOSC in operating model — physician-ownership, multi-specialty case mix, and facility-fee revenue — though at significantly greater scale.
• DISC Surgery Centers: Outpatient spine and orthopedic surgery centers in California, including locations in the Bay Area. Direct peer in robotic-assisted and minimally invasive outpatient joint and spine procedures — overlapping with WOSC's flagship orthopedics service.

Broad incumbents

• United Surgical Partners International (USPI): Largest U.S. operator of ambulatory surgery centers, owned by Tenet Healthcare. Comparable business model — physician joint-venture ASCs across multiple specialties — and a key potential consolidator in the same outpatient surgical category as WOSC.
• SCA Health (Optum): Optum-owned ASC and surgical care operator running multi-specialty outpatient facilities with physician partners nationwide. Closely comparable in operating model and specialty breadth to WOSC's ten-service-line offering.
• HCA Healthcare: Largest U.S. for-profit hospital operator with a growing outpatient surgery footprint. Indirect ASC competition in the Bay Area via affiliated physician networks and same-day surgical facilities.
• AMSURG (Envision): National ASC operator historically focused on GI and multi-specialty outpatient surgery. Operates physician-partnered facilities comparable in scope and specialty mix to WOSC's ten-service-line model.

Regional players

• Sutter Health: Major Northern California not-for-profit health system operating multiple outpatient surgery facilities across the Bay Area. Regional competitor for the same multi-specialty outpatient case volume in the East Bay.
• Stanford Health Care: Academic health system with outpatient surgery centers in the SF Bay Area. Competes for higher-acuity outpatient cases in orthopedics, ophthalmology, and GI, particularly for insured and employer-sponsored patients.

Others

• Privia Health: Physician-enablement platform supporting ambulatory groups including surgical practices. Adjacent ecosystem participant relevant to WOSC's physician-ownership model and potential outpatient-ASC consolidation.
• Washington Hospital Healthcare System: Adjacent acute-care hospital located directly across from WOSC. Functions primarily as WOSC's referral partner rather than competitor, but is a structural anchor of its referral pipeline and an example of hospital-affiliated outpatient capacity.
