Seeing his mother suffer on a daily basis from disabling psoriatic arthritis was the impetus for his going into medicine and rheumatology in particular.

Through a holistic approach combining conservative therapies, such as nutrition, bowel health, and physical therapy, with advanced medicinal therapies, he strives to improve his patient’s quality of life. He consistently aims to combine his clinical training skills with the latest in rheumatology research and supplements to improve patient care.
