Welcome to Cornerstone Medical Group

Providing the best primary care involves more than just the most up-to-date medical techniques and diagnostics. It involves spending time to get to know you to fully address your concerns.

We take the time to care for you.

We are a concierge medical practice providing personalized, comprehensive primary care medicine. Our practice limits the number of patients we see so that we can provide you with the personal attention that’s so often missing in today’s hurried doctors’ offices. This lets us look at the big picture of your unique healthcare concerns so we can focus on overall wellness, as well as treating your specific symptoms.

Our long-standing relationships with the best specialists in Boston and beyond ensure you get the very best care in a timely fashion. And, we coordinate that care for you. So you can concentrate on feeling better while we set up your appointments, quickly follow up on test results, and provide easy-to-understand counseling on next steps so that nothing falls through the cracks.
