About Jason

Learn Jason’s areas of practice.

Jason has been resolving a wide variety of family law cases, from simple to demanding. He has over a decade of unique expertise in high-conflict custody cases, many of which involve allegations of physical, emotional, or sexual abuse. Jason began his legal career working for the City of Phoenix Prosecutor's Office, trying criminal cases before juries and judges. This is highly unusual in a field in which the vast majority of both criminal and civil cases end up being settled out of court. Jason's trial experience as a prosecutor helped him develop the calm confidence and argumentative skill you want in family law court. His clients appreciate his ability to execute focused case strategy, communicate persuasively, connect with judges, assert dominance, and think critically in the moment.

divorce case
Working with Jason has been a pleasant experience. My divorce case has been very difficult and involves a special needs child. I previously hired another attorney that caused me to waste so much time and money. Luckily, I was referred to Jason by a disability law firm that had great feedback by other clients. Finding the right attorney is scary. With Jason, I was able to find comfort and confidence in my case. Jason is very knowledgeable and empathetic to your situation. He truly cares for your well being and what is in the best interest for you and your child/children. Jason and his paralegal Jill work very closely with one another to make sure your case is being handled in a timely manner. Communication and transparency is amazing. In addition, You will never be charged for anything without your knowledge or taken advantage of. Jason always makes himself available for you and is very quick to respond. I would highly recommend this lawyer to anyone that is looking for services.

Highly Recommend!
I hired Jason in 2017 to prevent my ex-husband from relocating to another state with my daughter. We have joint custody, but he was going to move her without my consent. The case just ended in May of 2018. Because of Jason's excellent representation, not only is my daughter still in Arizona most of the time, but I get to see her according to the Stipulated Order. For years, I did not spend time my daughter as much as I was supposed to see her according to the Parenting Plan. Over the years, I have hired two attorneys and gotten part of the way through a divorce. They were not very good at representing me, the situation became extremely difficult, and I did not finish the divorce. Then I hired another attorney and completed the divorce, but he did not do a good job. Jason's words to me as he looked at my divorce decree were, "You didn't have an attorney. Did you?". Needless to say, without good representation, my ex-husband did not see the need to follow the Parenting Plan. It has been extraordinarily painful not to see my daughter as much as I was supposed to see her. There appears to be many attorneys who do not have the skills or the motivation to represent their clients well. Jason has what it takes to do a great job for you. He returns calls and emails in a timely manner, communicates well to plan a good strategy, is very assertive and tough when necessary, and explains possible results as well as the cost. He brings his "A" game and I cannot say enough good about him!

Jason did an excellent job with my case. He is an expert at what he does! He always kept me in the loop of communication and necessary information. He was very professional, respectful of time/cost, and very, very knowledgable and experienced in the matters of the law. I felt very supported in my case and very grateful that he was recommended to me. He is an excellent attorney! I have and will continue to recommend Jason for his expertise to everyone I know.

AVVO RATING 7.8 (Very Good)

Professional misconduct

This lawyer was disciplined by a state licensing authority in 2018.

Reprimand issued in AZ, 2018
updated on 08/26/2019

This means the attorney did something wrong, but the Bar did not suspend the lawyer. Typically in this case the lawyer's poor behavior is exposed to the public in hopes that he or she will not repeat the behavior.

Jason's comment: “I accepted a reprimand for failing to have a client sign a waiver for a potential conflict of interest. I should have had her sign the wavier, but I thought the Firm was helping her finish her divorce and she needed our help.”
