OUTSTANDING ATTORNEY

A fearless fighter that has your back 1000%. Hiring Corey Brennan as a defense attorney ws the best decision I've ever made. He is the BEST attorney in the state. You want an attorney who is confident, thorough, and unshakably composed. He didn't just know the law -he knew how to communicate it cle...arly to the judge and jury. In trial he was a force to be reckoned with. He knows his stuff and doesn't back down. He combines skill, strategy and compassion. We are so grateful that we hired him to represent our family member. We got a good outcome to some very serious charges. Thank you so much to Corey Brennan! Hands down the BEST attorney! 5 stars! Highly recommend!!

Great attourney

I cannot express enough how grateful I am for the exceptional legal representation provided by Mr. Brennan. From our initial consultation, it was clear that I was in the hands of a true expert in criminal defense. He demonstrated an impressive understanding of the law and took the time to thoroughly ...explain every step of the process, alleviating my anxiety during a challenging time. Corey was not only incredibly knowledgeable but also genuinely invested in my case. He meticulously reviewed all aspects of the evidence, built a robust defense strategy, and was always available to address my concerns. His communication style was clear and professional, making me feel informed and supported every step of the way. The results of his hard work and dedication were nothing short of outstanding. I truly believe that without his expertise and commitment, the outcome could have been very different. I highly recommend Mr. Brennan to anyone in need of a knowledgeable, compassionate, and effective criminal defense attorney. He not only delivered results but also restored my faith in the legal system. Thank you, Corey, for your exceptional service!

Amazing lawyer!

After having another attorney for 4 months that didn’t do anything he said he would do, I hired Corey. Corey took the bull by the horns and took care of my legal needs in a timely fashion. Very professional, motivated and a knowledgeable lawyer… would definitely recommend him for your legal needs.

Phenomenal Attorney

He is the best Criminal Defense I’ve come across. An absolute bull dog, well respected, and IS the best you can retain. He is extremely knowledgeable and will fight for you. Extremely professional while still correction corruption of the justice system. I’ve even retained him before to fix previous a...ttorneys errors.

Life saving attorney

Corey is hands down the best thing that could have happened to me in my difficult situation. I was arrested and charged with 3 counts. Public intoxication, carrying a firearm while intoxicated, and carrying a firearm where alcohol is consumed. I am a medical professional and a single parent, my abili...ty to work and take care of my daughter became seriously jeopardized because of these charges. Corey worked day and night for me and my defense, he spent countless hours advising me and working with my DA. I was not the easiest client to handle as I would panic about my situation. Corey always made himself available to talk me down and keep me focused. He continued to strive to provide the best possible outcome for me and my family and he delivered on his word. Had it not been for Corey I really believe my life would be ruined, however because of his hard work I was able to come to a conclusion in my cases, through dismissals and deferments that not only kept me free and maintained my freedoms, but also allowed me to continue working in the medical field. If you ever find yourself in a legal issue, Corey is the man to hire, hands down!
