David O'Grady for neuropsych eval of third grader

 We recently received a referral to David O'Grady in Walnut Creek for a neuropsych evaluation of our young son. I can find very little online about him regarding patient reviews. Has anyone had experience with him testing their children? The one BPN message I saw about him was for adult therapy.  Wondering if we should get back on the list for Dr. mountain at Kaiser even though she has a four month waiting list.

Thanks
