GReat lawyer.
I got hurt after another car crashed into mine (I was actually the passenger). Mr. Diehl sued the driver of the other car who caused the wreck and the insurane company of the driver. It was kinda stressful, but he made me feel comfortable and got a settlement that really helped get me back on track. I thought he , -Tom Diehl, was great and fought to get the settlement from the start. thanks tom for all of your help!
