Real Clients, Real Reviews

The staff at Centennial Medical Group is always polite, professional, and welcoming! They are anxious to help and go out of their way to accommodate any unforeseen changes in scheduling. All the providers give the best care.
It’s very convenient to have the lab, the vaccine clinic, the allergy clinic, and physical therapy all in the same building. There’s even a pharmacy in the lower level.
We live in northern Maryland and continue to make the drive for quality care!
