    “Quality work and service!”

    I worked with Weily and his staff to develop my living trust. The process was very simple and Weily explained everything so I knew what the best route to go with my estate. Everything was done in a few weeks. I was provided and nice binder with tabs for easy reference. Quality work and service!

    “Weily Yang, who went above and beyond to ensure that we understood every step of the living trust process”

    Phenomenal experience with Mortensen & Reinheimer. Specifically, Attorney Weily Yang, who went above and beyond to ensure that we understood every step of the living trust process. He was a breadth of knowledge, very kind, and professional. I would highly recommend this business. There is absolutely no need to look any further. Lynette Burns (Executive Assistant) was very personable and courteous as well. She was also very adept at providing notary services. Additionally, we met President Robert Price who could not have been easy going and professional. He has quite the rubber ducky collection!

    “Very professional and knowledgeable”

    I worked with Weily Yang on creating and presenting a couple of seminars on special needs trusts and limited conservatorships to the local community. He was very professional and knowledgeable on the topics, did a great job presenting, and was patient in answering questions from families. Weily is obviously very well versed in this area and ensures that he is on top of the latest laws/case laws. I highly recommend him for any special needs trusts/limited conservatorship needs you may have!

    “I would refer them a million times over and over again.”
    After two years of working with this office practically on a daily basis, I think I am more than a credible person to review them. Wow did I get lucky to have Tamsen, Noah. Karlee, Steven, and Denitta to handle my difficult case for my mother's trust. You won't find anyone like Tamsen who takes great pride in her business. Making sure her client's needs are met at all times. At first, I was concerned that the case wasn't moving along quick enough. As time went on, I saw that they are really great chess players. Making mistakes with dumb moves is not in their vocabulary. My emails were always responded to ASAP, in which I love that. We finally were able to settle the case in mediation and let me tell you, Noah and Tamsen are incredibly sharp, well-spoken, professional and great at what they do. I am more than happy with Mortensen & Reinheimer, and I would refer them a million times over and over again.
