    “We offer the highest recommendation for any trust needs you may have.”

    Weily Yang and the entire staff there are nothing short of outstanding. Weily helped me and my siblings with the Trust transition for our elderly mother and also helped my wife and I with a long over-due revision of our personal trust. He was very patient and informative with the multitude of questions we all had and we could not have asked for anyone better. We offer the highest recommendation for any trust needs you may have.

    “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.

    “Peace of Mind”

    “Well done and thank you to everyone at Mortensen & Reinheimer, PC!”
    Mortensen & Reinheimer, PC is a great practice to turn to when addressing all the legals matters of family trusts. We had sought out Ms. Tamsen Reinheimer's expertise on another family trust matter and were so very pleased with her guidance and representation on that matter that we contracted her to update/restate our own family living trust. Not only was Ms. Reinheimer inviting and easy to speak with, she also provided a thorough and knowledgeable counsel on family trust laws as they related to our needs and desires for our restated trust and translated all of the legalese for us to easily understand. We are extremely pleased and satisfied with our final documents and will certainly turn to Ms. Reinheimer and the practice again for any future needs. All of the staff we encountered at the practice were kind and professional: Karlee, Lynette, Cathy and others were always friendly and attentive and responded to email communications promptly. Well done and thank you to everyone at Mortensen & Reinheimer, PC!

    “"Goes to the mat" for his Clients”

    This full service Trust law firm with Noah Herbold, Esq., helped us through a very complicated and difficult 2-stage Trust Settlement. This included letters, Filings and Court appearances. He is a Trust litigation attorney who really "goes to the mat" for his Clients. We have reached a satisfactory conclusion. He was recommended to me by another law firm, out of the area and we would not be where we are, today, without his help.
