    “Thorough and kind”
    Mr Noah Herbold helped my elderly mother with a very complicated conservatorship law suit brought about by her son. He listened carefully to my mother and advised her accordingly. He was thorough and kind with her and represented her well in court.

    “He is a true professional and really cares about his clients.”

    Weily Yang, Esq. of Mortensen & Reinheimer has been such a supportive partner for our special education Community Advisory Committee in Irvine. We have hosted parent education webinars on “Special Needs Trusts and Limited Conservatorship” for our special education families in the past 2 years with Weily as the presenter and have had an overwhelming positive response from all the families that we invited him again this year. He was very thorough, knowledgeable and professional in his delivery and made it easy for families to understand a very complex process. He answered all of our questions and was available by email for any follow up questions. He also recently attended our Abilities Awareness event at our Resource Fair and assisted families with legal questions. We highly recommend eliciting the help from Weily for any legal needs. He is a true professional and really cares about his clients.

    “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.
