About Gilberto Sustache, Jr. MD
Welcome to Sustache Primary Care in Marlborough, MA, where my focus is on your wellness. I offer a more individualized approach to healthcare with the MDVIP model. My aim is to put your health first while encouraging balance and self-care. With over 20 years in primary care, I can focus my education, experience and enthusiasm on you.
My MDVIP-affiliated practice offers services, including comprehensive, advanced health screenings and diagnostic tests, that go far beyond those found in concierge medicine practices. My practice size is smaller, which means I can offer conveniences like same- or next-day appointments with minimal waiting. It also means I have more time to spend with each patient to discuss primary care issues big and small.
If I’m privileged enough to meet you, I hope you’ll see that I love people. I am happily married for over 27 years and have three amazing kids. I love detailing cars for fun, and I am fluent in Spanish.
I hope you’ll feel encouraged to come and find out what my practice is all about. I appreciate you taking the time to look me up.

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.
