Patrick J. DeMarco, M.D Dr. DeMarco was one of the founding physicians of Allergy & Asthma Specialists of North Florida. He is board certified by the American Board of Allergy & Immunology- a conjoint board of American Board of Internal Medicine and American Board of Pediatrics. Dr. DeMarco believes that patient care starts with a strong bond between the physician and their patient, a relationship that is often lost in the fast-paced medical world of today. Patient education is essential to Dr. DeMarco and he spends a significant amount of time with his patients explaining medical diagnoses, testing and treatment options.
