John H Lewis Medical Center was founded on a simple belief: every person deserves a physician who knows them as an individual. Since opening our doors in Sandwich, we have grown from a single-practitioner office into a full-service family medicine center — but our philosophy has never changed.
Our practice sits at the intersection of clinical excellence and genuine human connection. When you walk through our doors on Jan Sebastian Drive, you are greeted by name, not by chart number. We take the time to listen, to explain, and to partner with you on decisions that affect your health and your life.
Our physicians and staff bring a combined decades of experience in family medicine, internal medicine, and preventive health.
Family Medicine
Dedicated to comprehensive family care with a focus on preventive medicine and chronic disease management across all age groups.
Internal Medicine
Specializes in adult medicine with expertise in managing complex chronic conditions and coordinating specialized referrals.
Nursing & Patient Care
Our nursing team provides patient education, coordinates care plans, and ensures every visit runs smoothly from check-in to follow-up.
The trust of our Sandwich community is our greatest achievement. Here is what some of our patients have shared.
I have been coming to John H Lewis Medical Center for over ten years. The staff remembers me by name, never rushes my appointments, and always takes the time to explain my options. It feels like a true partnership.
After moving to the Cape, I needed a new primary care provider. The entire team made me feel welcome from day one. They helped me transition my medications and set up a care plan that actually works for my schedule.
My mother has multiple chronic conditions and managing her care was overwhelming. This center coordinated everything — specialists, lab work, prescriptions. We finally feel like we have a medical home.
Whether you are establishing care for the first time or looking for a practice that truly listens, John H Lewis Medical Center is ready to welcome you. New patients are always welcome.
We are located in the heart of Sandwich with convenient access to Route 6A and the Mid-Cape Highway. New patients are always welcome.
