Liam has been great through the whole process from filling out my papers to letting me know what he needs. Calling me and texting me letting me know the progress of what's going on. If have questions, all I have to do is call him if he's not available he usually gets back to me the same day. He's been very sympathetic of what I've been through, losing my pets because of evacuating and just the whole evacuating process. I've been through some tough family times recently and Liam has been very sympathetic and tells me if I need anything he's always there just a phone call away. I would highly recommend McNichols and McNichols lawyers they have been awesome to me they are very informative about everything that's going on and keep me in the loop.

McNicholas law firm was helpful right from the beginning with the reality of the Dixie fire and helping with some xtra gas in our tanks and an informational meeting. They have always followed up on progress of litigation and timeline of case settlements even though it has been slow to assure they are working hard for clients. Thanks for helping us!

McNicholas & McNicholas, LLP was a lifesaver for us. They treated us with great kindness and understanding and listened very carefully to our input and our concerns. They took time to explain every step of the process of our lawsuit and to explain all of the ins and outs of what needed to be done. We were never left with any misunderstanding or wondering about what should or should not be done. We felt and we knew that we were in the best of hands. Another law firm was involved on our side of the suit and it was quickly obvious that they highly respected and highly regarded McNicholas & McNicholas and their opinions and help. We could not have chosen better.

If you had the great fortune of finding this law firm, please take a second to read my review of attorney Matthew McNicholas.

From the very beginning, I was very impressed with his professionalism and his interest in learning about me as a client. My particular situation was very complex and took several years to resolve.

Matthew McNicholas stayed by my side the entire time. I never felt as though I was alone. He never gave up on my case and he never gave up believing in me.

Matthew McNicholas restored my reputation and a settlement was reached beyond my expectations.

Sincerely,
William Cordero

I worked with the law firm McNicholas & McNicholas for my whistle blower and retaliation lawsuit against the Los Angeles police department. I was fortunate to have Courtney assigned as lead attorney for my case.
I could not have found a better attorney for my case. Courtney expertly guided me through the difficult and stressful process of filing a lawsuit. Through it all she was professional, honest and kept me prepared.
Courtney was never too busy to take my call or answer any of my many questions. I appreciated her attention to detail and allowing me to give input on our case. Courtney has a humility that is certainly rare amongst attorneys, and especially amongst the top attorneys like herself. But her demeanor changes when it’s time to take care of business. Courtney is well prepared and expects the opposing counsel to be prepared as well. She is tenacious and fought for me to be heard and compensated. Courtney is one of the best attorneys I have ever seen, but what really makes her special is she cares about her clients. I am truly grateful to have had her for counsel and I would not hesitate to use her again. I will gladly give Courtney whatever your highest rating is. Thank you Stuart Guidry

In November 2015 I consulted with McNicholas & McNicholas regarding a work place retaliation issue. After an extensive consultation the firm agreed to take on my case against the City of Los Angeles. I was completely satisfied with all the steps that were taken during the initial phases of this case. Courtney was assigned as the lead attorney for my case in September of 2016. I cannot say enough positive things about my interactions with Courtney. She is a true professional and extremely competitive at the same time. No matter what phase of the case we were in I had the utmost confidence that Courtney had my back and would represent me to the fullest. It was incredibly refreshing to know during these stressful times that your attorney was was equally passionate about all of the phases. The entire firm shares the same positive work ethic. Because of the outstanding work of McNicholas & McNicholas I prevailed and settled my case. I still maintain a great friendship with Courtney to this date due to the many things she taught me during the long process of this case. I have, and will continue to recommend this firm to all of the people I know in various professions. Thank You
