    “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.

    “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!
