About Concierge Medicine in Thousand Oaks
Thousand Oaks sits at the western edge of the LA metro in the Conejo Valley, straddling the LA/Ventura County border. With 11 practices, it has a mature concierge market anchored by Los Robles Hospital.
The Conejo Valley is different from the Westside or Beverly Hills. This is a family-oriented suburban community. Amgen, one of the world's largest biotech companies, is headquartered here. The patient base is biotech executives, Amgen scientists, and affluent families drawn to the Conejo Valley's schools, safety, and outdoor access. Concierge medicine here is more medically traditional (internal medicine, prevention, chronic disease management) and less performance/longevity-oriented than Beverly Hills.
Four physicians offer concierge at $2,500/year: Hema V. Nathan, MD (five decades clinical experience, Los Robles affiliation), Peter Margolis, MD (four decades, former Chief of Medicine at Los Robles), Francoise Menteer, MD (Harvard-trained, currently full), and Jonathan Rosaasen, MD (founded 2013, currently full). Irina Feldman, MD ($3,300/year, Castle Connolly Top Doctor 2011-2024) brings a functional medicine focus. House Call Doctor Thousand Oaks (5 physicians, $400-$1,100 per visit, 211 combined years of experience) serves patients at home with FDA-certified equipment.
Los Robles Hospital is the local hospital anchor. For academic specialist care, UCLA Health (45 minutes east) and Cedars-Sinai (30 minutes east, depending on traffic) are the referral destinations. For context on how concierge medicine pricing works across the US, Thousand Oaks is moderately priced.
How to Choose a Concierge Doctor in Thousand Oaks
- $2,500/year is the standard. Four physicians at this price point creates a market where the decision is about physician fit, not price. Focus on specialization, hospital affiliations, and panel availability. Our guide on how to choose the right concierge or DPC doctor covers evaluation factors.
- Menteer and Rosaasen are full. Two of the four $2,500 physicians are not accepting patients. Nathan and Margolis are your options at this price point.
- House calls are available. House Call Doctor Thousand Oaks has 5 physicians covering the Conejo Valley with FDA-certified at-home equipment. This is a per-visit model ($400-$1,100), not a membership.
- Los Robles is the local anchor. Nathan and Margolis both have Los Robles Hospital affiliations. For UCLA or Cedars-Sinai referrals, ask about your doctor's academic hospital relationships. Understanding the key differences between concierge medicine and DPC is less relevant here since the market is entirely concierge.
