What Our Families Are Saying
Dr. Garrison and his staff are just the best!!!! I could not ask for a better pediatrician for my son!! I would highly recommend them to anyone!
We just switched to them and I’m so glad we did! The office is beautiful and clean and everyone there is very friendly and helpful.
As stressful as it can be to bring your sick child into the pediatrician’s office, the staff at St. Clair Pediatric’s always know how to provide a calm & comforting environment! The care provided by their staff is nothing short of spectacular.
