  • "Dr Kostur and her staff are friendly and highly professional. The staff is well equipped to make sure your visit is safe and efficient. They have safety protocols set in place for sick visits which I really appreciated. I would highly recommend Jax Kids Pediatrics to anyone looking for a practice that really cares about your child’s health."

  • "As an OB/GYN, I am often approached by expectant mothers to recommend a pediatrician. Without hesitation, I endorse Dr. Kostur. She is not only a colleague but has cared for both of my children from birth. She approaches her job with a good balance of compassion and knowledge. She is sensible and approachable. She is always thorough, but does not order unnecessary tests. Her office is well run and the staff is helpful and accommodating. I would not think about taking my children to another pediatric office!"
    S.D., Ponte Vedra Beach, FL
  • "I have been taking my son to Dr. Kostur for the last 12 years and words can not describe how happy I have been with her care. She is very detail oriented, extremely knowledgeable, always listens to my concerns and has my child's best interest in mind at all times. She treats my son as if he were her own and I love that about her. My son is now 17 and does not want to go see an adult Dr. He only wants to see Dr. Kostur."
