About William Harris

Dr. Harris made the decision to pursue a career in medicine, specifically allergy and immunology, because he has always been fascinated with science and wanted to help people overcome their health concerns. To do this, he made sure that he had the educational background and up-to-date training to give his patients the best care possible. After earning his medical degree, Dr. Harris completed residency training in internal medicine and fellowship training in allergy and immunology.

“I see patients who are experiencing chest tightness, shortness of breath, coughing and itchy skin, to name a few, and through comprehensive testing I am able to identify the cause of their symptoms. I then provide them with individualized treatments designed for effective, lasting relief.”

Dr. Harris prides himself on providing his patients with unhurried and informative care in a relaxed environment. He will take the time to explain their diagnoses and any recommended treatment in simple, easy-to-understand terms.

“My patients appreciate this level of personalized care; it makes their office visits a positive experience.”
