About Thomas C. Keller, DO
For more than 22 years, I have had the privilege of caring for patients in the Hanover, Pennsylvania, community with a deep sense of responsibility, pride and dedication. My mission has always been rooted in building deeper relationships, delivering personalized care and serving each patient as an individual—not just a set of symptoms.
I spent decades in traditional practice, and I believe that the current healthcare system—often driven by third-party constraints and administrative demands—can limit the time, attention and personalization that patients receive but patients deserve. In response, I chose to practice under a personalized care model in affiliation with MDVIP. This allows me to return to the core values that first inspired me to practice medicine.
In this model, I am able to spend more time with my patients, develop stronger physician-patient relationships and focus on proactive, preventive care. I am committed to helping patients better understand their health and supporting them as they work to reduce long-term risks and improve their overall quality of life.
I believe that individualized medicine begins with trust, communication and time. By creating a more patient-centered practice, my goal is to provide the kind of care I would want for my own family—compassionate, experienced and truly personal.
Caring for others remains both my profession and passion, and I look forward to continuing to serve my community in a more impactful way for years to come.

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.
