I am a Montana native born and raised in the Helena area.  I enjoy what the Montana outdoors has to offer and have raised my 5 children here too.  Hard work and perseverance have blessed my family and I.  

 My legal background includes work in family law and as a public defender in my early years before being elected County Attorney in 2003.  Part of my duties in Jefferson County included working as the public administrator where I worked on probate cases.  I also joined the Montana Army National Guard and served as a JAG until December 2013 retiring as a Captain.  I gained experience in drafting wills, counseling soldiers with legal questions, and defending soldiers that required military boards.  

Upon re-starting my private practice in 2015, I represent clients in Criminal Defense, Family Law, Family Services cases and Estates/Probates and Wills.

Excellent service
I would highly recommend Matt. He did an excellent job for me and in a very timely manner. My last experience with an attorney left a very sour taste in my mouth, so working with Matt was a breath of fresh air. I highly recommend him.

Great attorney - very versatile
Matt is a terrific attorney - very down-to-earth, easy to communicate with and does what he say he will do when he says he will do it. Not only does he have good legal judgement, he exercise a lot of common sense. He managed a child custody issue for my grandson - expertly, efficiently and fairly. Subsequently, he also managed a criminal case which he was able to resolve without a lengthy court a plea bargain that was a great deal for everyone. Although prepared for a court battle, it wasn't necessary. You won't be disappointed with Matt. His prices are reasonable and he is a nice guy!

Excellent Attorney
Matt is an outstanding Attorney. He represented me very well in a criminal court case that went to a full jury trial. We got a "Not Guilty" verdict in about an hour of Jury deliberation. After the verdict was read one Juror mentioned to me personally that I had a very good attorney. Matt is also very timely in responding to his clients. That to me is very important because especially in my situation it was extremely stressful. Matt Johnson literally saved my life and career as I know it. I highly recommend him to anyone seeking a good attorney.

Excellent Attorney
Matt is amazing at what he does! In my very stressful situation he was reassuring, easy to communicate with and knowledgeable about the law in my case. He responded back with answers or other options in a timely manner. I do not live in the county my case was filed in. Matt went above what was necessary to make sure I was kept informed with what was going on in my case. He made things work so I didn't have to take off lot of time from work and do a bunch of traveling. I wouldn't be where I am if it wasn't for his help. I would highly recommend him as an attorney for your case!
