I have been a patient of Dr. Diehl's for over 10 years. He has followed my developing cataracts with care and accuracy, performing surgery to replace a lens. He stays on track during exams and does not visit. His exams are very thorough. I was awake during the surgery and felt very comfortable with his warm manner and excellent staff. I have recommended Dr. Diehl to friends and will continue to do so.

People have one opportunity to make a first impression. While I don't question his qualifications, his bedside manner is atrocious. The fact that this guy deals with people does make me question the quality of doctors that group health has on staff. Theres no nice way to say it. He's a jerk. Plain and simple.
