    Jason is a formidable trial attorney who has earned a reputation for fighting for his clients. I have been fortunate over the years to witness him first hand in the courtroom.

  • Mark Alan Rohrbaugh

    Jason has demonstrated himself to be one of the "go go" criminal defense lawyers in this community. I have seen him affectively handle everything from simple traffic matters to high level felonies. I have complete confidence in his ability and would recommend him to anyone.
