Mr.Mayen is extremely professional and what stood out for me was how he communicated to me throughout the case. He was able to get me a deal that helped me getting my case to be diverted into Pre trial diversion.

Mr. Mayen got the job done.

My court cases were prolonged years due to filing issues then Covid, yet Mayen kept super efficient notes as well as stayed on top of all possible outcomes for the cases. Mr. Mayen dealt with my temperament very well, he explained court processes over and over when asked and ultimately he a got us ...a not guilty sentence. 9/10 I would recommend!

Excellent results!

At the beginning of the case, I just wanted to give up, but then I got this lawyer and he stuck with me until the end and we won! He was great at explaining stuff and keeping me up to date on things. When the other side tried to push on things, this attorney was professional and smooth in convincin...g the judge the case had no merit, and I walked away not only with a win, but knowing I made the right decision with this attorney.

Rockstar lawyer!!!!

First off Gustavo Mayen went above and beyond with my case. I had some pretty serious charges and he was able to get me on CWAF. I was shook!!! Not only that but he was so great with following up and making sure I was getting the things done I needed done on my end. He has saved my life so much alrea...dy tremendously. He is so great!!! He made sure I understand my rights. We went over everything thoroughly, never felt rushed. He listened, he cared. Do yourself a favor and reach out to this man if you have any legal issues you need help with. Promise you will not be disappointed!!!!
