Dr. Lewis was born and raised in Arizona. One only has to look to his 2nd grade school reports to trace his desire to be a veterinarian. After graduation from Arizona State University and marrying his high school sweetheart, Dr. Lewis attended Colorado State University where he obtained his Doctor of Veterinary Medicine degree in 1986. He then worked at Mesa Veterinary Hospital for two years before starting his residency in dermatology. In 1991 he finished his residency and achieved Diplomate certification by the American College of Veterinary Dermatology.

Dr. Lewis founded the Dermatology Clinic for Animals (later Dermatology for Animals) in 1991 with offices in Mesa, and Tucson, Arizona as well as in Albuquerque, New Mexico. Within three years clinics were added in Salt Lake City, Utah, El Paso, Texas and Omaha, Nebraska. By bringing a clinic to these cities, it meant that, for the first time, residents of the state had a board- certified veterinary dermatologist to treat the severely afflicted dermatology patient.

Dr. Lewis has a passion for the veterinary profession and the specialty of dermatology. His principle interest includes investigating the role of allergies and the effect they have on the skin. Improving the quality of life for a severely allergic patient is a challenge Dr. Lewis loves to accept and fulfill. Dr. Lewis has written journal articles and supported research on a number of projects during his career. He is frequently invited to lecture at veterinary continuing education meetings around the country, and is always eager to share with his colleagues some of the insights he has gained regarding dermatology disorders in animals.
