Drs. Davis, Singh, and Mathavan offer expertise and precision in their surgical practice that flows from experience, a love for the craft of surgery, and dedication to their patients. Teaching the future generation of surgeons through the Residency and Fellowship programs at St. Vincent keeps us current and innovative.

Dr. Singh and his staff were outstanding. They explained everything to me about what had caused the problem and what they would do during surgery. While recovering, I never even had pain medication. Absolutely the best!
