5 / 5 stars
Allan Castillo is more than just a lawyer. I hired Alan as my lawyer because I made a huge mistake and drove after drinking , resulting in an accident. Going through one of the hardest times of my life, I cant even imagine having anyone else defend me and would only recommend him to anyone else if they were ever in that situation. Alan not only worked relentlessly on getting me the best results in my case, but also helped with my sobriety, pointing me in the direction that would help me as a man. Having Alan as my lawyer was more like having a family member or best friend defending me. There was not one time during my case that I ever doubted his ability to get the best results. During my case Alan went through his own trials with a very serious illness that would have caused almost anyone to quit and put their health above others. Alan did not do that, after getting out of the hospital when he should have been home resting, he was back in the court room fighting for me. Alan is much more than a lawyer, he a remarkable man who has helped to get me a second chance at life. Alan is more of a role model not just for lawyers but for all of us, if we all fought as hard for each other as Alan did for me, in and out of the court room, this world would be a much better place. Thank You Alan for giving me a second chance in life.
