Practice History

Founded in 1968 by Dr. Howard Levine, the Center for Rheumatic Diseases and Osteoporosis was the first rheumatology practice established in Montgomery County. We have cared for more than 100,000 patients referred by hundreds of physicians. Our patients come from as far north as Gettysburg, PA, from as far east as Annapolis and Delaware, and from D.C. and many counties in Virginia.

We participate with almost all locally available medical insurance plans including Medicare, Aetna, all Care First products including Blue Choice, United Healthcare including all Mamsi products, Johns Hopkins health plans, Cigna, OneNet PPO, and Adventist Healthnet. We are committed to continuing participation in as many insurance plans as possible, to allow continuity of care for our patients.

We are an integrated medical practice providing a full range of services to patients with rheumatic disorders and/or osteoporosis, including physician consultations and ongoing care for rheumatic diseases; DXA scan interpretation and physician consultation and ongoing care for osteoporosis; and on-site infusion therapy and laboratory blood drawing facilities.
