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.- Rob W.

Phenomenal experience with Mortensen & Reinheimer. Specifically, Attorney Weily Yang, who went above and beyond to ensure that we understood every step of the living trust process. He was a breadth of knowledge, very kind, and professional. I would highly recommend this business. There is absolutely no need to look any further. Lynette Burns (Executive Assistant) was very personable and courteous as well. She was also very adept at providing notary services. Additionally, we met President Robert Price who could not have been easy going and professional. He has quite the rubber ducky collection!

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.- Craig T.
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. -

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. -
Tamsen has the perfect blend of wonderful people skills, the ability to distill complex concepts into understandable language, and tremendous depth of knowledge. I have referred a number of my clients to her, and all have been extremely happy with the advice and resultant estate plans provided…- Annette F.
