Client testimonials

"Walter was compassionate yet realistic regarding my situation. He explained every step of the process in ways that I could understand, took nothing for granted, and wound up getting the charges dismissed."

"Walter represented me with an aggressive no-quit attitude. He took charge and never misrepresented what he was willing to do or could do for my situation. Walter was always very patient with all my questions and I felt like I could call with anything that was not clear to me."

"Walter was always very patient with all my questions and I felt like I could call with anything that was not clear to me."​

"·      Attorney Piel handled my case in a professional and expeditious manner. I was very satisfied with his representation of me and completely resolved my case." 

"I was involved in a car accident after I had been drinking. The police charged me with two felonies. Walt came to my house and drove all the way across two counties to sit at my kitchen table and hear my story about that night. He made no promises, but I could hear a very strong, solid, reliable, honest, trustworthy, experienced man sitting
in front of me speaking. I immediately retained his services.
That was the best decision I ever made."
