Pediatrician Staff

McKinney Pediatrics was founded by Dr. Robert Neal in 1983. Our doctors and nurse practitioners have been caring for the children of McKinney for over 30 years. The children Dr. Neal began caring for when he started the practice are now bringing their children to McKinney Pediatrics for their healthcare needs.

Meet our team at McKinney Pediatrics!

Please take a few moments to learn about our skilled practitioners and our friendly, nurturing staff.

At McKinney Pediatrics, we consider it both a great joy and responsibility to care for children. Most of us are parents ourselves, so we strive to be understanding and available to the families we are privileged to serve. We are honored that you have chosen us as your child's primary medical provider and are confident that you will be pleased with the quality of care and service that we can provide you and your family.

A vital part of our service to children begins with our outstanding staff who works hard to manage and maintain a professional, caring and supportive environment for our patients in a timely manner. Our doctors are lifelong learners. Not only have they received advanced medical training in pediatrics, they continually pursue ongoing education to stay abreast of the latest in child health care.

Your child's health is as important to us as it is to you. We look forward to providing you with excellent medical care your child deserves.
