  • Jacob Thomas Erickson

    I endorse this lawyer. I have known Mr. Decker from before he was licensed to practice law when I worked with him at his former employer. Though young, Mr. Decker was able to obtain very favorable results for his clients. He specializes in family law and criminal defense and is a true court room attorney. He has actual court room experience that gives him more skill than many other attorneys his age. He has a personable demeanor that lets his clients know he is a real person and cares about their case.
