The Rheumatic Disease Clinic of Houston is one of the Bayou City’s oldest rheumatology practices. Just south of the Medical Center on Alameda Road, RDCH serves the greater Houston area with quality, specialized care. Spearheaded by Dr. Samuel Pegram, RDCH has grown from a single practice in 1986 to a full clinic providing primary physicians, imaging and scanning, infusions , as well as clinical research.
