Riverside Sanitarium LLC

Riverside Sanitarium LLC, doing business as Riverside Behavioral Healthcare Center, is a for-profit limited liability partnership based in Riverside, California, that provides nursing home care and behavioral health services to veterans as a prime contractor exclusively to a single federal customer—the Department of Veterans Affairs Veterans Integrated Service Network 22 (VISN 22)—competing without set-aside protections in a full-and-open environment. The vendor operates as a sole-source healthcare provider to the VA Loma Linda Healthcare System and Jerry L. Pettis Memorial VA Medical Center in Southern California, with all 73 recent prime awards (100% of footprint) flowing from VISN 22 and carrying combined potential value of $30.8 million.

Riverside's capability portfolio centers on inpatient psychiatric treatment, acute mental health services, short-term behavioral health intervention, and skilled nursing facility care for the veteran population. The vendor holds multiple indefinite delivery vehicles with VISN 22: a $7.775 million nursing home care contract awarded April 1, 2026 (running through March 31, 2031); a $1.5 million Indefinite Delivery, Indefinite Quantity (IDIQ) contract for community nursing home services; a $1 million single-award Indefinite Delivery Contract for short-term behavioral health services (December 1, 2025 through March 31, 2026); a $692,043 single-award indefinite delivery contract for on-demand inpatient psychiatric and acute mental health services; and a $5 million single-award Basic Ordering Agreement for behavioral healthcare services. Representative delivery orders under these vehicles include a $220,402 fixed-price order (February 1, 2026) for express reporting and behavioral health services, a $231,661 order (January 1, 2026), and a $600,000 order (March 1, 2025) for short-term community nursing home services at the Riverside Behavioral facility. Delivery orders typically range from $22,800 to $600,000 and are structured as firm fixed-price contracts with economic price adjustment.

Customer concentration is absolute: VISN 22 represents 100% of awards and 100% of combined potential value. The vendor performs all work in Riverside, California, supporting the VA Loma Linda Healthcare System and Jerry L. Pettis Memorial VA Medical Center. Activity has grown from ten awards in 2022 to fifteen in 2025, with three awards recorded in 2026. The vendor's top parent vehicles are a $3.8 million Basic Ordering Agreement (29 task orders), an Indefinite Delivery Contract with $3.1 million combined value (17 task orders), and another Indefinite Delivery Contract with $2.1 million combined value (10 task orders). Riverside has obligated $10.7 million against the $30.8 million combined potential value across all awards (35% obligations rate), indicating substantial remaining capacity under its existing vehicles.

Registered in SAM.gov since May 22, 2007, Riverside operates under primary NAICS 621610 (Nursing Care Facilities / Skilled Nursing Facilities) and PSC code M (Nursing Home, Long-Term & Adult Day Care Services). The vendor carries no federal contract vehicles, no IDIQs, and no GWACs in its own right—all work flows through VISN 22–issued vehicles. Riverside does not subcontract and has no sub-award footprint; the business model is direct prime delivery of healthcare services.
