He tried homicides, serial crimes, DUI cases and nearly every type of felony, misdemeanor and traffic offense. He became intimately familiar with the perspectives, procedures and philosophies of the prosecution and law enforcement community.

An Attorney You Can Trust

“Phil fought for me and I will be forever grateful. I felt and still do, that he honestly cared about the outcome of my case and completely committed himself to winning. Phil treated me with respect and never seemed judgmental or pushy. Some lawyers are so set on doing things their way that you get the feeling that you are just a payday, not with Phil. I would recommend his services to anyone 100 percent.” ★★★★★
