“Jim saved us a bunch of time, money and aggravation with his cool head, knowledge and skilled responses”

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.

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.

“Weily Yang, who went above and beyond to ensure that we understood every step of the living trust process”

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!

He took the time to ensure we understood each step of the process and made what could have been an overwhelming experience feel manageable and supported. His deep involvement in the special needs community—especially through giving educational talks about special needs trusts—shows his true commitment to families like ours.

We highly recommend Weily Yang to anyone seeking trustworthy, knowledgeable, and compassionate legal guidance in this area.
