    “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.

    “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!
