Dr. Rolf R. Drinhaus operates a medical practice on Hancock Avenue in Murrieta, serving the broader Temecula Valley and surrounding communities. The practice handles general internal medicine and primary care — the kind of appointment-based office where established patients manage chronic conditions, receive preventive screenings, and get referrals to specialists when needed. This is not an urgent-care walk-in; it's a traditional primary-care model built around continuity with a single provider. The patient base skews toward adults managing ongoing health needs rather than acute episodic care, and toward those with insurance coverage and established provider relationships. For residents new to the area or changing providers, Drinhaus takes new patients through standard medical-office channels — insurance verification, chart transfer, first-appointment paperwork. For anyone in the valley without a primary-care anchor or needing a doctor who knows their history and medication list, an established internal-medicine practice like this fills that role more efficiently than urgent care or emergency department visits would.
Livingwater's Medical Clinic operates as a primary care practice in Murrieta, serving the general medical needs of adult and family patients across the city and surrounding valley communities. As an independent clinic rather than part of a larger hospital system or regional network, the practice handles routine checkups, acute care visits, chronic disease management, and preventive medicine in a smaller-group setting where continuity with the same provider is the operational model rather than the exception. The practice suits residents who prefer a stable doctor-patient relationship over the rotation common at larger urgent-care chains or hospital-affiliated clinics. Insurance acceptance varies by plan; calling ahead to confirm coverage before the first visit is standard practice with independent medical offices. For specialists (cardiology, orthopedics, dermatology) or hospital-level care, patients would be referred out; Livingwater's sits in the first-contact lane for the everyday medical questions and preventive care that keep most people out of the ER.

Optum operates a primary care clinic on California Oaks Road in Murrieta, functioning as part of the larger Optum health system rather than an independent practice. The clinic handles family medicine and general internal medicine — the kind of setup where residents establish ongoing relationships with a primary care provider, manage chronic conditions, and access referrals to specialists within the Optum network. The patient base skews toward insured adults and families with coverage plans that recognize Optum's in-network status, since the clinic is deeply integrated into that system's insurance and referral structure. For residents already enrolled in an Optum health plan or looking to establish a primary care home, this location provides that anchor point; those with different insurance carriers may find their plans have negotiated different networks. Wait times and appointment availability shift seasonally, and the clinic generally handles routine care, preventive visits, and prescription management rather than urgent acute visits or procedures requiring hospital-level facilities.
I started seeing Dr Farzin back in his old office in murrieta by inland valley hospital a few years ago, I was unhappy with my doctor in murrieta I felt like she was not listening to my health concerns at all and she was sending me to the wrong places with wrong dxs. So I switched over to Dr. Farzin...
I agree with previous reviews. This office has gone downhill since Dr. Tang retired. I constantly get sent the wrong dosage for my prescription. Once I called to get my prescription and I was scolded for not asking earlier even though it was previous auto-refilled. Now I keep having issues with lab ...
I've been a patient here for 21 years. There was a noticeable increase in issues with communication/confusion under the new owners, but things seemed fine for the most part. Then I was notified I'd need to start seeing a specialist within 3 months to continue getting the same medication at the same ...
What Locals Know
Murrieta's rapid growth has strained primary care capacity — established large-network clinics like Optum compete with independent practices for patient panels. UnitedHealth integration means streamlined billing and care coordination for their members, but non-network patients may face higher out-of-pocket costs.
