“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.

“He is a true professional and really cares about his clients.”

Weily Yang, Esq. of Mortensen & Reinheimer has been such a supportive partner for our special education Community Advisory Committee in Irvine. We have hosted parent education webinars on “Special Needs Trusts and Limited Conservatorship” for our special education families in the past 2 years with Weily as the presenter and have had an overwhelming positive response from all the families that we invited him again this year. He was very thorough, knowledgeable and professional in his delivery and made it easy for families to understand a very complex process. He answered all of our questions and was available by email for any follow up questions. He also recently attended our Abilities Awareness event at our Resource Fair and assisted families with legal questions. We highly recommend eliciting the help from Weily for any legal needs. He is a true professional and really cares about his clients.

“Extremely professional from start to finish”

We were referred to Tamsen Reinheimer to help us prepare our trust, and she and her staff were extremely professional from start to finish. Having a trust done properly is of upmost importance and you want to have someone prepare it that has the experience.

“What stood out most was their thoroughness—nothing was rushed, nothing overlooked”

I recently completed my estate planning—including my will and trust—with Mortensen & Reinheimer, PC, and I could not be more impressed with the entire experience! From the very first consultation to the final signing, every step felt smooth, thoughtful, and incredibly well-guided.

The team at their Irvine office on Michelle Drive was warm, attentive, and exceptionally knowledgeable. They took the time to understand my unique situation, explained complex concepts in a way that was easy to grasp, and made sure I felt confident and protected in every decision I made. Their professionalism was matched by genuine care, which made a process that can feel overwhelming surprisingly comfortable.

What stood out most was their thoroughness—nothing was rushed, nothing overlooked. They were proactive with communication, quick to respond to questions, and clearly committed to delivering an estate plan that was both comprehensive and tailored.

If you're looking for a trustworthy, highly skilled law firm to help you create or update your estate plan, Mortensen & Reinheimer, PC is an outstanding choice. I’m incredibly grateful for their guidance and truly feel at peace knowing everything is in order.

“Thorough and kind”

Mr Noah Herbold helped my elderly mother with a very complicated conservatorship law suit brought about by her son. He listened carefully to my mother and advised her accordingly. He was thorough and kind with her and represented her well in court.
