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.

I am a board-certified Endocrinologist, who has been serving the Lancaster community since 2007. I also studied at the University of Missouri-Columbia and have a Master's degree in Nutritional Sciences. My special interest in nutrition has helped me to manage patients with diabetes mellitus. I also treat a wide variety of endocrine diseases that include osteoporosis, thyroid and parathyroid disorders, pituitary gland disease, adrenal gland disease and low testosterone. I believe every person is unique and deserves individualized care to achieve maximal health in both body and mind.
