I Googled DUI attorneys in my area, and numerous firms were provided by the search. As I was reviewing each one, I kept going back to Dischley Law Firm. There were several reasons they piqued my interest. First, Mr. Dischley was a Marine and Marines are fighters and are squared away. That gave me confidence in his ability.
