About
At Centennial Medical Group, eight physicians and certified registered nurse practitioners deliver comprehensive primary care from two Columbia, Maryland locations. The practice has served Howard County for 25 years and now cares for approximately 30,000 active patients. Internists, family physicians, and advanced practice providers share a team-based philosophy that places patients and families at the center of every care decision.
The practice houses an on-site lab, digital X-ray, pharmacy, physical therapy, and an allergy clinic under one roof. Services extend well beyond primary care to include urgent care supervised by an emergency physician, medical weight loss, occupational health, travel medicine, echocardiograms, bone density scanning, and IV therapy. Centennial Research Center has managed more than 60 clinical trials since 2005, working alongside major pharmaceutical companies. For patients who want enhanced access, the Premier Access concierge program offers same-day and next-day priority appointments, 24/7 direct physician contact, and extended annual physicals.
