    “I want to thank you both very much for all that you did.”
    I received your letter indicating the discharge of the Estate probate. I want to thank you both very much for all that you did to steer me through uncharted waters and your constant and professional handling of all the details that were required. I want you to know that I will offer a positive recommendation to your firm should I encounter any friend or associate that would need your services.

    “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!
