    “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!

    “Easy, quick, straightforward”
    Easy, quick, straightforward. Tamsen and her team made something difficult to do (estate planning with death in mind) extremely easy. I’d definitely recommend them for any estate planning needs.

    “"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.
