About Collin D. Cullen, MD

I was raised in a primary care household with an admiration for family medicine. I had a front row seat, as my father was a general practitioner in the DC area for 30 years. Practicing primary care with my brothers over the last 21 years has been the most rewarding part of my career; learning from some of the finest and giving patients optimal care. My MDVIP-affiliated practice focuses on the relationship between the physician and the patient. My approach is grounded in the belief that the doctor-patient connection is the foundation of all successful healthcare. Listening to the patient has always been the most important diagnostic test. I also offer conveniences, like same- or next-day appointments that start on time, which may be found in concierge medicine practices.   

As a native Washingtonian, I have served the Northwest DC, Montgomery County, Maryland and Sibley Hospital communities my entire professional life. I am dedicated to preventive medicine and am uniquely qualified to serve this area because this is where, and how, I was raised.

She was hospitalized several times and finally had to undergo antibiotic IV infusion over a nine week period from mid-November through mid-January. During that entire time we were away, including the holidays, Dr. Collin Cullen kept in touch with…

My story has more to do with consistency than any specific occurrence. Dr. Cullen has always been incredibly responsive regardless of the day of the week, or the time of day. It’s very comforting to know I can depend on him to be there for me when called upon.

In December I had annual mammogram and was told something questionable showed up. I would need to have another mammogram as well as an ultrasound. After having that done I was told I needed to have a biopsy of the area. As a breast cancer survivor I was naturally nervous an very concerned. Before scheduling the biopsy I wanted to talk to Dr. Cullen, my PCP. I was able to talk with him…

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.
