GET PERSONALIZED CARE ANYWHERE.

We’re expanding our services and locations.

Diplomat helps specialty patients in all U.S. states and territories. Beyond our 600,000-square-foot headquarters in Flint, Michigan, we have locations across the country.

WE’RE BECOMING MORE.

But we’re still focused on patient care.

The healthcare world isn’t static, and neither are we. Diplomat is adding services and expertise across the specialty continuum. Everything we do ultimately helps our patients, guided by the words of our cofounder, Dale Hagerman: “Take good care of patients and the rest falls into place.”
