Brett has a great strength of Character along with a very articulated communication style. Brett immediately comprehended the nature, character and sensibility of my case and plan a meticulous strategy that allowed me to gained more positive points that I have ever did in 4 years of process with my previous attorney . Brett has a high level of expertise and a remarkable knowledge in Family Law ; This is only after a month that I have retained Brett to represent my case; that Brett with his level of knowledge and expertise in the management of my case that I was immediately reconnected with my daughter who was separated from me for over 6 months. Brett is the attorney of integrity and Honesty and moreover his human character make him completely reliable and accountable. With no hesitation I would highly recommend Brett for his unique skills and ability to manage divorce and separation cases.

Interviewed Eight and Went With Brett
I interviewed eight attorneys before deciding to go with Brett Thorsteinson. And I'm glad I went with him. Brett was particularly strong on the financial issues involved and demonstrated an ability to cut through a sea of facts and figures to know exactly what mattered and what didn't. I was also struck by his professional manner, capacity to objectively enter the fray to represent my interests, and genuine desire to see a just outcome in the face of a very unjust situation. In a profession where there are a number of crooks who will inflate themselves and run your bill up needlessly, Brett stands out as an attorney who is knowledgeable, ethical and no-nonsense. I would and will hire him again should I find myself in need.

highly recommend
Mr. Thorsteinson helped me get through a very difficult time in my life. I am thankful for the results we were able to achieve. He was knowledgable and explained in detail the different scenarios I could be faced with. Mr. Thorsteinson fought compassionately and aggressively for me when were forced to go to court. I would give Brett my highest recommendation.

Thorsteinson Law Group is experienced and committed
Brett is always two steps ahead and always kept me informed as we navigated the legal process. He continually advised me on my best course of action, and always responded to my questions as quickly as possible which set my mind at ease. It was clear the first time I spoke with Brett, he was concerned for my well-being, protecting my rights and getting me the best possible outcome.

This Attorney is On Point
Mr. Thorsteinson is on point!! He is a very talented gentleman. He is experienced in the legal field and knows all the aspects of family law. Not only is he professional but he has a genuine and sincere side to him. Going through any issues that require an attorney in family law could be a very difficult time for many people in their lives and Mr. Thorsteinson does a good job at comforting his clients but at the same time gives them a taste of reality and won't sugar coat any advice he gives. I completely recommend this attorney for any family law issues you may have.

I hired Brett to represent me in my divorce and he was awful. He blew through my retainer and more and did not improve my position in the case at all. He did not keep me informed or recommend every option available. It seemed like he just wanted to do whatever was easiest for him. Every time I spoke with him about the case it was like he was hearing things for the first time. Thank God my ex and I are on good terms because if I had left it up to Brett, I would have missed my custody mediation appointment. He didn't even tell me about it, but my ex did. DO NOT HIRE THIS LAWYER , you will not get good representation.
