Didn't like his bed side manner, he can explain things medically like he knows what he's doing but I'm not so sure he does. I like going to a dr that you can say anything to and they listen not look at you like why are you telling me. We'll be trying a different Rheumatology Doc.

Dr. Diehl is an excellent doctor who actually communicates with his patients. He spent 1-1/2 hours on my first appt and followed thru by referring me to pertinent doctors. I highly recommend him!

Dr. Diehl was hard to get in quickly, but luckily there was a cancellation. He was very helpful, and spent 40 minutes with me for a first appointment. He was very compassionate and listened and actually looked at me as I was explaining symptoms. I would highly recommend him.
