My training is focused in Rheumatoid arthritis, Psoriatic arthritis/Spondyloarthropathy, PMR, Vasculitis (GPA), Sjogren's and Osteoporosis. Since joining the group in 2002, I have enjoyed working in the Lancaster, PA area. I have always felt honored to assist people and enjoy the long term relationship building with patients and their families. I hope to continue learning and treating our patients with the latest therapeutics available for rheumatologic diseases and osteoporosis.
