I have two children ages 3&4 and we have been going to Mesa Peds since they were born. We have seen all the doctors and PA's in this office and they are all good. We saw Bill Gause when my son was about 6 months and we haven't seen any of the other docs since. (Except once when he was off and we had to be seen right away) My daughter was born with kidney issues and had many many visits to the office, hospital and eventually surgery. Bill was wonderful thru it all. He would call us after her hospital visits or visits where she had big issues just to check how she AND I were doing. We've been in a lot over the last 6 months with my son having odd symptoms and he never sent me away with an "i dont know" answer...he kept looking for answers and found out he had Mono. He is so good about calling me when I have questions or concerns. I love the nurse and I've never had issues with the staff either. When my daughter racked up a huge bill from her hospital visits they were very helpful with payment arrangements and never pressured me when I was a little late paying them. I love this Peds office and recommend them to everyone.
