Fantastic Attorney with Great Legal Skills and Dedication
I hired Attorney Matt Long after I was indicted on serious criminal charges. Matt worked tirelessly to review all the evidence and make the appropriate motions to win the case. After reviewing his motions, all the most serious felony counts of the indictment were dismissed. On the remaining felony counts, Matt was also able to have them dismissed in exchange for a plea to an offense that is treated as a misdemeanor with probation. I am grateful for all the time and effort he and his staff put into my case and for achieving an excellent result. I highly recommend Matt Long in the area of criminal law.

Matt Long Saved My Life
Matt professionally negotiated an unexpected path through complex extreme legal peril. He has been honest & direct from the moment I met him. I always felt Matt held a personal vested interest in my future legal & personal disposition. Matt's extensive experience within the legal system was applied with careful attention to the smallest of details. I had no one to trust & no where to turn when I called Matt. I quickly realized this was the best decision I could have possibly made. If you have a problem & you need a real Lawyer; Matt is your guy..

Mathew will get you through the tough time
I feel very lucky to have had Mathew represent me in court. He knows the Arizona court system and will let you know how things should go. He gave me his personal cell number and replied back to calls and text the same day, himself. I was surprised at the level of 1 on 1 communication we had. Mathew will explain the extent of the law to you so you have a clear understanding of the Arizona laws.. I only lived in AZ for 3 weeks before I had my issue. He is ethical and honest, exactly what anyone should be looking for in an attorney... Thanks Matt!

Only the Best and the Brightest with this man
My nephew is getting a deal when he is clearly guilty, and Mr. Long has explained the case to me as much as he can without breaching his attorney-client privilege. I am sending him an email and my sisters and I will sign affidavits to assist him in getting the best leniency for my nephew as possible under these tragic circumstances. I recommend Mr. Long to anyone in trouble with the law. I myself am a Paralegal, and he is an astute and quite passionate advocate for his clients, and in particular, I am talking about sex crimes involving children. He has an understanding of the psychopathology involved in each case and comes up with a theory himself based upon his interactions with the client. He challenged me and I spent 6 hours working in the wee hours to provide him assistance with getting the most out of this plea. Which HE brokered, and which only HE could broker, because of his reputation with the Court. I am very impressed with Mr. Long and his ability to touch his jurists with his passion and clarity. Thank you so much, Matt.

Excellent and professional
Mr. Long was very articulated and kind with helping me in my situation. He was clearly very knowledgable and because of this knowledge it was comforting. If you want an attorney that is on the ball extremely professional and speaks the truth but says it in a way you can understand.... Mr. Long is clearly your attorney if choice.

The best Arizona has to offer
Him and his lovely wife represented me as if I was family. Hiring Matthew to be my lawyer was the best decision I've made in quite sometime. I cannot explain in words what him and his wife mean to me. I strongly recommend Matthew Long.
