What our members are saying

Dr. G is my salvation. Whether I am at an appointment or calling for immediate help, he always has time. In May of 2011, he responded to my call that I had a 99 blocked carotid artery. This was found by Lifeline Screening. He immediately set me up for another ultrasound, which confirmed the prior result. Then I had a 3D cat scan which reconfirmed and I was then scheduled for hospital…

Dr. Gassner is one fine doctor. Period! In fact, he's the best sawbones I've ever been treated by. However, I still think he should remove his ring when he slips on the latex glove!!!!!

I like seeing Dr. Gassner. He spends the time I need with me, and does not rush me out. He explains things in a way I can understand.. When I have tests, he gives me the results by calling me the next day.

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.
