Our daughter also had her surgery done at Children's by Dr. Diamond. She is now 3 1/2 yrs. She was 8 mos for first her surgery. He closely monitored her progress through cystoscopies and completed the process when she was 2yrs. She will be all set til 5 when he'll recheck through a physical exam with other checks during crucial developmental periods. We have been very satisfied with the care he has provided our daughter. We have since had questions and he has proven to be prompt with call backs and answers. Good luck and God Bless. Hope all goes well. If I can be of any help please let me know.
