What Our Clients Say About Us

  • "We recently changed physicians and started coming to pediagroup for our 4 and 6 year old and couldn't be happier! Drs Walker and Gould always take the time to carefully examine my children and answer all of our many questions. The front desk staff was great at getting my sick child seen the same day and helpful with my billing and insurance questions. The nurses take their time with my children and help make them feel at ease. When you have 2 children with rare genetic conditions it is very difficult finding a physician. Happy my children are in great hands"
    Nicole Baker
  • "Dr. Gould and Dr. Walker are by far one of the best pediatricians . I’ve been going to Pediagroup Associates for 21 years now. My children's now 21, 19 and 18 were patients of Dr. Gould since day one. Now my Grandbabies are patients of Pediagroup. They take the time to examine their patients and answer any questions. I love Pediagroup and I would definitely recommend Pediagroup Associates to any new parent or anyone looking to switch Pediatricians."
    Letty Garcia
  • "We've been very happy with Dr. Gould and her staff. They are all very polite and quick. We've had good experiences with getting in when our children are ill, and getting needed forms and referrals in a timely manner. Dr. Gould is especially pleasant and always a pleasure to see."
    Robert Douglas
  • "My kids have been going here for 17 years. Very good care."
