Has Anyone Seen Dr. Diedtrich from Dr. Thoburn's Office?

If so, please fill me in on any and all you can tell me about him. I was supposed to see Dr. Thoburn but switched to Dr. Diedtrich due to time issues (sooner appts. available) My friend tells me I should have stayed with Dr. Thoburn cause he's the best! HELP!
