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.

Kelly L. McKerahan, D.O. operates a medical practice on Jefferson Avenue in Murrieta, positioned in the retail corridor where many residents already manage routine office visits and primary-care appointments. The practice handles general internal medicine and family medicine — the breadth of adult and family care rather than a focused specialty — making it a baseline choice for patients building a relationship with a single provider or needing a referral source for specialists elsewhere in the Inland Empire. The patient base runs primarily to adults and families seeking continuity care: established patients returning for chronic-condition management, newer Murrieta residents establishing a local primary-care anchor, and anyone needing a provider who can triage urgent concerns without a dedicated urgent-care visit. For pediatric-focused care, a pediatrics practice would be the fit; for specialists like cardiology or dermatology, McKerahan's role is typically the referring point rather than the destination. Most Murrieta patients will recognize the Jefferson Avenue location as accessible during a standard weekday work-break or after-school window.
Dr. McKerahan is very thorough and explained in detail the issues I was having. Due to post operative medications I am taking, he is willing to wait before ordering new meds for new conditions. He takes the time to evaluate every issue.
Has been our Dr for years. Very compassionate. He listens to you and does rush. He is very thorough. He saw on an ekg and ordered more testing my husband had to have open heart surgery. I wouldn't trust my health with anyone else. Good Christian man
Dr McKerahan is old school patient service! He comes in, he listens, he takes his time to hear you out and we can joke with him as well. We love having him as our family doctor.
What Locals Know
Murrieta's medical landscape includes both independent practitioners and larger multi-specialty groups. Solo or small-group providers on Jefferson Avenue tend to offer more direct access and continuity but may have narrower specialist referral networks than hospital-affiliated offices.
