Chris Mahan is an amazing attorney. I have sent many, many friends and colleagues to him after he helped me with my divorce. I was so happy with the time and energy he put into my case, and I know he does the same for all of his clients. I would have paid much more than the rate he charged for his services. Worth every penny!

Mary M.

Beverly Hills, CA

We needed a trust for our elderly parents. We went to Les Grossman. Mr. Grossman charged us substantially less for the trust documents than other attorneys we consulted with. Mr. Grossman is also the most professional and knowledgeable attorney we ever met. A year later when we needed some modifications he helped us for free.

James C.

Chatsworth, CA

From ALL the attorneys we met with, Chris was the only one who really listened to our concerns and the only one who took his time giving us detailed answers. Working with him was amazing. He made everything clear for us, he is honest and truthful. We highly recommend him if you need a Divorce attorney.
