About Jonathan Rosaasen, MD
When I started medical school twenty years ago, I had no idea what I was getting into. I had an idealistic view of how the system should be and what my role in it would be as a primary care physician. Initially, I worked for a large HMO group and then a government run facility. Volume was often the goal over quality.
When the opportunity of private practice presented itself ten years ago, I jumped on it. I needed to spend time with my patients, get to know them and find out what is important to them. I needed the time to develop a relationship. Private practice provided for that type of personalized healthcare, but as my practice has grown, it has become more difficult to give each patient the time and attention that they deserve. When looking for a solution to the problem of volume driven medicine, I decided to partner with MDVIP. In my MDVIP-affiliated practice, l will keep me up to date with the latest advances in medicine and have the time to better address the healthcare goals of my patients.
I am excited about this new stage in my practice. I am working with each patient to create health goals specific to their needs and motivate them through frequent contact and availability. I will work together with each patient on current trends, guidelines and research while helping them choose their ideal path towards a healthy and fulfilling life. Emphasis on prevention and lifestyle modification will always come before medications. Weight loss and control, general health through diet and proper nutrition, exercise and mental wellness are my key focus for my patients to achieve better health. My MDVIP-affiliated practice, often compared to a concierge medicine practice, also offers conveniences like same- or next-day appointments. I look forward to getting to know each of my patients better and advocating for them. My practice serves Ventura County and is located close to Moorpark, Simi Valley, Thousand Oaks and Westlake Village. I am affiliated with Simi Valley Hospital and Los Robles Hospital. I maintain board certification in Family Medicine.

Frequently Asked Questions
Doctors who operate in the MDVIP models typically see far fewer patients than traditional primary care doctors. That gives them more time to develop deeper doctor-patient relationships that can lead to better outcomes. They can also offer conveniences that most primary care doctors can’t, including same- and next-day appointments. They’re available after hours for urgent matters. And they have time to focus on prevention. That focus begins with the MDVIP Wellness Program, which patients pay for with their annual membership fee.
Most MDVIP-affiliated primary care practices accept insurance (your physician can tell you whether they accept your specific insurance plan). Your annual fee pays for preventive care medical services that insurance usually doesn’t cover (e.g., advanced diagnostic testing and screenings). Your MDVIP-affiliated physician will continue to bill your insurance and charge copays, co-insurances and deductibles as he or she currently does for other medical services like sick visits.
MDVIP makes wellness and prevention easier by providing your physician with innovative tools and technology. MDVIP supports your physician’s practice and seeks to eliminate barriers to a positive healthcare experience. Your doctor will determine whether and how to incorporate these tools at his/her discretion.
