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!!

OKC’s best lawyer

My experience with Mr. Brennan representing me was nothing below excellent. I had never been in trouble before and I was very scared, nervous, and honestly just confused about the whole situation at first. Once I got Mr. Brennan involved it was like a weight being taken off of my chest! He handled ev...erything and walked me through everything that was going on Inside and outside of the courtroom. He reassured me consistently and never got tired of my questions! He truly took my case over and did an incredible job with it. In the future, I will 100% be coming to him for any advice or legal help because he simply cares for each of his clients. He truly wants you to feel good about what is going on and to take some of that “panic” feeling out of the equation! He will have your back the whole way.

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!

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.

Excellent!

I called Me. Brennan unsure of what my legal options were. He explained my options in detail with terms that I could understand. Hopefully I will never need an attorney again but if I do I will be calling him again!
