Welcome to Cornerstone Endocrinology – St. Clair Shores

Welcome to Cornerstone Endocrinology. Our mission is to provide the highest quality care for all forms of Endocrine disorders. 

Our Board Certified Endocrinologists have decades of experience. This enables us to understand the individual needs of our patients. Using the latest scientific advances, we blend compassion and the latest in technology to address your concerns; not forgetting that human-to-human interaction is the cornerstone of the physician and patient relationship.  We would like to welcome Omama Siddiqui MD as a physician provider to our group to help support our patient’s needs.   

For our diabetic patients; our Diabetologists utilize the most sophisticated treatments including point of care rapid results, insulin pumps, and continuous glucose monitoring systems.

Got Questions?
We Have Answers.

We’re a multi‑specialty group serving metro Detroit with over 80 physicians and mid‑level providers across 28 locations. Our services include family practice, internal medicine, pediatrics, endocrinology, hospitalists, podiatry, and colorectal surgery. All physicians are on staff at an Ascension hospital, and we’re affiliated with most local hospitals in the area.

For over 30 years, we’ve been serving patients throughout Macomb, Wayne, and Lapeer Counties—and have recently expanded with a pediatric location in Oakland County.

Our network of offices is designated as Patient‑Centered Medical Homes. That means we coordinate comprehensive care that positions you—not just your physician and staff—as the central figure in managing your health.

  • Schedule appointments
