Dr. Katie Dalton

Dr. Dalton received her Bachelor of Science in Microbiology at the University of Oklahoma. She then went on to her medical training at Oklahoma State University College of Osteopathic Medicine. She completed her pediatric residency at the University of Oklahoma. After residency, she completed an additional year of training in caring for children in the hospital and worked for 3 more years as a pediatric hospitalist for OU-Tulsa Department of Pediatrics. In 2009, she joined the other physicians in opening Tulsa Pediatric Urgent Care. She loves working at TPUC because the patients and caregivers she encounters keep her on her toes, and she gets to have more time to take care of her toddler and volunteer at the school and various activities in which her older children participate. She enjoys being healthy with yoga, Pilates and hiking/jogging, as well as continually working to get her 3 children to eat vegetables!
