Parents know: Kids don’t come with an owner’s manual, and they don’t operate on anyone else’s schedule. The pediatricians at Mercy Clinic Pediatrics on Old Tesson Road in St. Louis, MO, provide a friendly, warm environment for babies and big kids too. Our entire pediatric team works with moms and dads to keep kids healthy and take care of them through all life's little illnesses and bigger health issues.
