Both my wife and I were extremely pleased with the experience, the testing, and the diagnosis that resulted. We enjoyed both meeting and working with Dr Parmer and his assistant.

11/19/2025

Dr Parmer came highly recommended to me by my PCP. He was welcoming, extremely professional; his education and training observed but not self-promoted. I did not know what to expect. The tests were so diverse and so difficult--this was not a game, this was a science. Stephanie was warm and professional as well, a standardized attitude which kept results accurate. I am grateful to have had this opportunity, and for good results, I was exhausted when I left, a bit overwhelmed, and left with suggestions for some simple steps to appreciate being 80, to let perfectionism, lists, and disordered attachments go in order to find joy. I think the knowledge that Dr Parmer has should be available to so many. Such an important area of wellbeing. [PHI removed]
