Appointments for Sharp Rees-Stealy Gastroenterologists are by referral from a Sharp Rees-Stealy primary care physician only. I strive to provide high-quality, patient-centered care with the most up-to-date information and technology possible. In essence, my goal is to provide the same level of care that I would want for myself or family. As a young college student I worked for some very gifted physicians who not only possessed outstanding medical knowledge and skills but simultaneously practiced a humanistic medicine that provided great solace and compassion for their patients. I continue to endeavor to emulate these characteristics in my career. My hobbies include playing soccer, backpacking/hiking and traveling (to name just a few).
