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!

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.

Criminal Defense Attorney

I called Mr. Brennan in August of 2016 looking for an attorney for what I thought was going to be a situation that was surely going to affect the rest of my life. Mr. Brennan right from the start was re-assuring and as well I felt like he cared about genuinely helping me and not just trying to collec...t a pay check. From the start we created a plan to move forward and he gave me great advice. He constantly made sure I knew of upcoming events such as when the DA filed charges, and what I needed to do the instant that happened. He had recommended a excellent Bail Bonds company, as well as walked me through the book in process once charges were filed. Mr. Brennan made sure I always knew when and where my court dates were, and what had happened at those hearings. Through out the entire process which lasted over a period of 15 months he was right by my side with me the whole expierence. He exhausted every option that would benefit me as his client before it was all over, which mind was a dissmisal by the way. Throughout the entire experience I felt like Mr. Brennan was the best attorney I could of hired for this unexpected event and now that it's over Mr. Brennan constantly checks in with me and makes sure everything is going well. Cory Brennan who I consider a friend now, I would recommend him to anyone in anytime that needs help. I guarantee he will be there for you throughout the entire time.
