COMPREHENSIVE HEALTHCARE is a primary care medical practice founded in 2009 by Diane London, MD to offer personalized services and high-quality responsive patient care to members.

COMPREHENSIVE HEALTHCARE offers a broad array of benefits to members as well as access to clinical services offered by London Medical Group, LLC through Dr. Diane London and her staff.

Membership in COMPREHENSIVE HEALTHCARE is limited to approximately 300 members. As such, each member receives more time and more personalized attention than is possible or practical in a traditional medical office setting. When a clinical need arises for a member at COMPREHENSIVE HEALTHCARE, the staff works diligently to ensure that the member’s need is addressed the same day.

We recognize and value the importance of each member’s unique and individual needs. At COMPREHENSIVE HEALTHCARE, our patient advocacy covers a wide variety of individualized benefits that range from services such as coordinating individual care for members both locally and out of state, customized administrative assistance with billing to assistance with health insurance complexities, and more.

The practice’s primary affiliation is with Beth Israel Lahey Health, but Dr.London often works with and has privileges at other hospital systems in the area.

Her office has a secure electronic medical records system.

It is our goal to provide the best possible care to all of our adult patients irrespective of age, race, ethnicity, sexual identity, sexual orientation, or gender.
