    “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.

    “"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.

    “Jim saved us a bunch of time, money and aggravation with his cool head, knowledge and skilled responses”
    I had to deal with a bunch of different law firms during a 4 year legal battle and lawsuit over a family trust as the trustee. I switched law firms 4 times because they just ran up costs and never solved anything.

    On our first meeting, Jim ( an owner ) first said "Is there a way we can discuss with the other parties how to settle this without more legal fees and courts? " I've never had an attorney start off with how can we reduce costs and settle quicker!

    The other side was past that point and with Jim we prepared to move forward with the court case but Jim flagged a bunch of their false claims and said we wouldn't back down.

    A couple weeks before the first court date they reached out and accepted what was offered 2 years before and we all signed off on an agreement and settlement.

    Jim saved us a bunch of time, money and aggravation with his cool head, knowledge and skilled responses.
