About Us

Pediatric Gastroenterology, Hepatology and Nutrition of Florida, P.A. provides comprehensive evaluation, diagnostic procedures and therapy for infants, children and adolescents with disorders of the stomach, intestines, colon, liver, pancreas and nutrition. The group was started in 1983 by Daniel T. McClenathan, M.D. in St. Petersburg, Florida and currently includes twelve Pediatric Gastroenterologists and twelve Nurse Practitioners. Our physicians have all completed three years of residency training in Pediatrics and three additional years of training in Pediatric Gastroenterology and Nutrition.

All of our physicians are proficient diagnosticians, a skill essential for the accurate evaluation of our patients with abdominal pain, poor weight gain, vomiting, diarrhea and constipation. Most children occasionally experience one or more of these symptoms. Some children, however, develop recurrent symptoms, which interrupt their normal life, inhibit their development, disrupt their school performance and affect their emotional well-being and self-esteem.
