  • About

    Dr. Reitsma is an experienced clinician and educator who spent the first part of her career in a traditional internal medicine private practice, and the second half in hospital medicine and medical education. She enjoys educating her patients about their illnesses to empower them to make the changes needed to live happy fulfilling healthy lives. She is returning back to primary care because she misses the relational aspect of medicine, and looks forward to partnering with her patients to support their health goals. She is passionate about medical education, and is excited to continue to support the educational mission of Michigan Medicine after spending the last three years in Naples Florida where she was a faculty member at NCH Healthcare System (member of Mayo Clinic Care Network).
