Meet our Physicians

At Arthritis Centers of Texas, we are focused on the needs of our patients. We understand how frustrating and devastating rheumatic diseases can be. This is why we strive to provide thoughtful care to patients, whether the problem is a benign commonplace problem or a complicated life-threatening illness. In this era of rapidly expanding treatment options, we are committed to the timely and appropriate use of both established and cutting edge therapies. We believe in tailoring therapy to the needs of our patients. Arthritis Centers of Texas has nine board-certified rheumatologists and two rheumatology-trained nurse practitioners. We diagnose and treat a full spectrum of musculoskeletal pain syndromes and rheumatic diseases, including regional pain syndromes, fibromyalgia, osteoarthritis, rheumatoid arthritis, seronegative spondyloarthropathies, gout, osteoporosis, lupus, and vasculitides. As a consultative rheumatology practice, we cooperate with primary care physicians and other specialists to provide comprehensive care to our patients.
