RHEUMATOLOGY ASSOCIATES OF BALTIMORE LLC

What RHEUMATOLOGY ASSOCIATES OF BALTIMORE LLC does

Rheumatology Associates of Baltimore LLC is an independent, physician-owned rheumatology medical practice founded in 1987 by Dr. Howard W. Hauptman and headquartered in a single office at 1220B E. Joppa Road in Towson, Maryland. The practice employs 17 staff, including nine clinical providers (seven board-certified rheumatologists and two certified nurse practitioners with backgrounds in orthopedics and bone health), and serves adult patients in the Baltimore/Towson metro with diagnosis and ongoing management of rheumatic diseases, connective tissue disorders, autoimmune conditions, vasculitis, and osteoporosis. Services are delivered through an integrated on-site stack that includes physician consultations, an infusion suite for biologic and IV therapies, DEXA bone-density imaging, on-site laboratory services, adult vaccinations, and telehealth follow-up visits.

The practice's underlying technology is conventional clinical infrastructure rather than a proprietary platform: it uses a NextGen Healthcare patient portal for scheduling, records, and secure messaging, and Phreesia for patient intake and referring-provider appointment requests. Dr. Hauptman holds the Head of Division of Rheumatology role at both Greater Baltimore Medical Center and Medstar Franklin Square Hospital Center, granting admitting and consulting privileges that support hospital-based consultations and inpatient care, and he serves as part-time faculty at the Johns Hopkins School of Medicine.

Revenue is generated on a fee-for-service basis through insurance billing for office consultations, infusion therapy, diagnostic imaging, lab work, and vaccinations; pricing is not publicly disclosed. The go-to-market model is referral-driven, relying on primary-care and specialist physicians, community outreach (including an October 2025 open house that drew over 130 referring providers), the practice website, and word-of-mouth. The practice is privately held by its physician members, with no disclosed external capital, parent company, or institutional ownership.
