About

Summary: The page appears to be a listing for Spectrum Health Ludington Hospital Family Medicine (Corewell Health) rather than for a cardiology doctor in Niles, MI. Corewell Health operates as Spectrum Health in Ludington and provides primary care and other services. Key details include its Ludington, MI headquarters, multiple contact numbers, and page metrics (about 11k monthly visits, low bounce rate). The extracted content focuses on family medicine and general healthcare services, not specifically on a cardiologist named Dr. Ogubay T Mesmer in Niles, MI. If you’re seeking Dr. Ogubay T Mesmer, MD (Cardiology) at Corewell Health in Niles, please provide a direct link or allow me to search for the Niles cardiology profile, as this page does not appear to host that physician.
