    “The entire office staff have been a blessing to our family”
    We've been client of Tamsen Reinheimer for little over twelve years. Tamsen and the entire office staff have been a blessing to our family. The entire team not only are professional, but our family feels like being part of the team. I really cannot find the correct words to thank them all for their help in past and years to come. Many thanks!

    “Outstanding Service!”
    Tamsen Reinheimer gave my father the peace of mind he needed right before he passed. She came to our home to have him sign his Will/Trust. He passed five hours later. Tamsen has been supportive through the entire process. I have now retained her to update my Will/Trust. Karlee, her paralegal, is top-notch too. Everyone in the office is friendly and professional!

    “Patient, understanding, incredibly thorough”

    I had a delicate family matter following the death of my mother and I was concerned about the execution of my parents trust. Weily was fantastic to work with. Patient, understanding, incredibly thorough, and provided a perfect amount of communication. This firm is a great option. Thanks

    “I would refer them a million times over and over again.”
    After two years of working with this office practically on a daily basis, I think I am more than a credible person to review them. Wow did I get lucky to have Tamsen, Noah. Karlee, Steven, and Denitta to handle my difficult case for my mother's trust. You won't find anyone like Tamsen who takes great pride in her business. Making sure her client's needs are met at all times. At first, I was concerned that the case wasn't moving along quick enough. As time went on, I saw that they are really great chess players. Making mistakes with dumb moves is not in their vocabulary. My emails were always responded to ASAP, in which I love that. We finally were able to settle the case in mediation and let me tell you, Noah and Tamsen are incredibly sharp, well-spoken, professional and great at what they do. I am more than happy with Mortensen & Reinheimer, and I would refer them a million times over and over again.

    “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.
