About Benjamin H. Greiner, DO, MPH

True healing begins with a genuine connection. This is the deep-seated belief in the heart of my personalized primary care practice, a connection that goes beyond the clinical and touches the human spirit. As a board-certified Internal Medicine physician and Officer in the Army National Guard, I've seen firsthand how resilience and proactive care can transform lives. My own journey has been shaped by a passion for forming strong, trusting relationships with my patients, drawing on my expertise to deliver comprehensive primary care that helps tackle even the most complex medical conditions with precision and empathy.

I approach medicine holistically, recognizing that health isn't just about treating symptoms - it's about nurturing the whole person: body, mind, and spirit. By integrating evidence-based lifestyle changes, nutritional guidance, stress management techniques, and complementary therapies alongside traditional medical interventions, I help patients unlock their innate potential for wellness.

What sets my practice apart is the time I dedicate to each individual. I offer extended appointment times - often 30 minutes to an hour or more - so we can dive deep into your concerns without the rush of a typical office visit. This allows us to explore your unique story, uncover root causes, and craft personalized plans that fit your life. I know health doesn't operate on a 9-to-5 schedule, so I provide 24/7 availability to me via phone, text, or secure messaging, in addition to same day/next day appointments. Whether it's a late-night question about a new symptom or guidance during a stressful moment, I'm here as your steadfast partner, ensuring you never feel alone in your health journey. While Medicare has discontinued coverage for video visits in most cases, I continue to offer this service as illness can strike whether you’re on vacation or a business trip out of state. Additionally, my MDVIP-affiliated practice offers services, including comprehensive, advanced health screenings and diagnostic tests that go far beyond those found in concierge medicine practices.

Honest, open communication is the foundation of everything I do. I'm passionate about building lifelong bonds through education and motivational interviewing, empowering you to take the reins on your health. This collaborative spirit turns patients into active participants, creating partnerships that lead to lasting change. My mission is simple: to deliver quality care with the trust and compassion I'd demand for my own family. Every patient is seen as a unique individual, deserving of tailored attention and an unyielding commitment to their well-being.

With over 50 peer-reviewed papers on chronic-disease reversal and behavioral health, I’ve proven - again and again - that small, sustained lifestyle shifts can reignite energy, libido, memory, mood, and heart strength, often slashing medication lists in half. My job is to hand you the evidence, the roadmap, and the skills needed so you can run the play.

Medicine, to me, is a sacred conversation.

You bring your life; I bring my stethoscope, my research, my phone at 2 a.m., and the same fierce protectiveness I’d give my own parents. Together we turn “managing illness” into “mastering wellness.”

If that sounds like the kind of doctor-patient relationship you’ve been craving, let’s start the conversation today. Your brighter, stronger tomorrow is already waiting.

Dr. Greiner is one of the most attentive and caring doctor I have ever had in my adult life, he does not rush and actually asks me a patient questions, and listens to what I am experiencing at the time of my illness, and he goes above and beyond to make sure I got the right treatment. I will stay with him as long as he practices medicine.

Dr. Benjamin Greiner is the most caring doctor. He always makes time to see us when we need him and treats us with such genuine compassion and respect. He talks with you like a trusted friend while still being the knowledgeable physician you can rely on. He truly listens, looks at you when you’re speaking, and makes you feel like what you’re going through truly matters. His support and kindness mean so much to us. It’s rare to find a doctor who cares this deeply, and we are so grateful to have found him.

Dr. Greiner, thank you for the compassion, time, and attention you give so generously. We truly appreciate all that you do and feel so thankful to be in your care.

Dr Greiner is a wonderful doctor -- the kind I've been searching for! It's rare these days to find a doctor who truly listens to the patient's concerns, reads the chart BEFORE coming into the exam room, and is quickly responsive to online portal messages. My family has had the unfortunate experiences of doctors who only want the yearly blood work done, and then MIGHT refill your prescriptions, if you're lucky. Dr Greiner is simply the best!

Dr. Greiner is an incredible doctor! He really listens to you and validates your concerns. He is very patient and I never feel rushed when I am in the office. He responds to my questions promptly on the portal, too! It’s evident he cares deeply about his patients and his job — it is reflected in the quality care you receive as his patient. I feel so lucky to have found an excellent doctor!

I have already referred several people to Dr. Greiner and today was my first visit. This is the first doctor that I felt at ease while we reviewed my chart. He had already researched my medical history. I would definitely recommend Dr. Greiner!

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.
