John Muir Medical Center–Walnut Creek on Ygnacio Valley Road is the county's only Level II trauma center, a designation it has held since 1986, and since February 2024 its campus has also housed the 155,000-square-foot UCSF–John Muir Health Hofmann Cancer Center. Kaiser Permanente runs its Walnut Creek Medical Center on South Main Street downtown and the Park Shadelands Medical Offices on Lennon Lane. Sutter Health operates an outpatient center on Treat Boulevard and an endoscopy and surgery center on Lennon Lane. The densest medical office strip is La Casa Via, next to John Muir, lined with medical office buildings including the Shell Ridge Medical Office Buildings. Walnut Creek draws patients from across the I-680 corridor, which supports specialty practices that want to be near hospital services.

View All FAQs? Where do medical practices cluster in Walnut Creek?
The largest cluster surrounds John Muir Medical Center at 1601 Ygnacio Valley Road. La Casa Via, just off Ygnacio Valley, is lined with medical office buildings, including the Shell Ridge Medical Office Buildings and John Muir's imaging and radiation oncology building.

? What hospitals serve Walnut Creek?
Walnut Creek has two hospitals: John Muir Medical Center–Walnut Creek on Ygnacio Valley Road, Contra Costa County's only Level II trauma center, and Kaiser Permanente's Walnut Creek Medical Center at 1425 South Main Street. Since February 2024 the John Muir campus has also housed the 155,000-square-foot UCSF–John Muir Health Hofmann Cancer Center, and Sutter Health runs outpatient and surgery centers on Treat Boulevard and Lennon Lane.
? Why do specialists choose Walnut Creek?
Walnut Creek combines the county's only Level II trauma center, a major Kaiser medical center and, since 2024, a large UCSF–John Muir cancer center, which together draw patients from across central Contra Costa County and the I-680 corridor. Specialists who rely on hospital-based services or referrals from these systems tend to locate near John Muir on La Casa Via or near Kaiser's downtown and Shadelands campuses.
? Should I lease space near a hospital?
Hospital proximity offers advantages including referral relationships, shared patient populations, and perceived prestige. However, hospital-adjacent properties often command premium rents. Consider whether your specialty benefits from hospital proximity (surgeons, specialists) or whether a community location might better serve your patient base (primary care, pediatrics, dentistry).
? What is a "medical corridor" or "healthcare district"?
Medical corridors or healthcare districts are geographic areas with high concentrations of healthcare facilities, often anchored by hospitals. Locating within these areas can provide benefits including patient convenience, referral network proximity, shared parking arrangements, and established wayfinding. The Bay Area has several prominent medical corridors in cities like Palo Alto, San Jose, and San Francisco.
? What factors influence medical office rents in California?
Medical office rents vary with location (proximity to hospitals and medical corridors), building quality and age, the condition of the space (second-generation medical space with existing exam rooms and plumbing typically leases for more than shell space), lease structure (NNN versus full-service gross), the tenant improvement allowance offered, parking availability, and local supply. Rents also tend to be higher in supply-constrained markets such as Palo Alto and San Francisco than in suburban markets.
