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.

One of the best in Oklahoma
Straightforward, knowledgeable, and experienced. He explained in detail what he could happen and what to expect. Things went exactly like he expected them to and always kept me informed. He was 100% worth my time, trust, and money.

Outstanding attorney
He goes above and beyond. He is patient with you and never looks down on you for what you have done. When he says he will do something he will. He blows the rest of the attorneys out of the water.

Mr. Brennan never got tired of answering my questions. He was welcoming, understanding, and persistent. Without him I would of been a confused paranoid mess. 10/10 lawyer.

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 attorneys errors.

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 everything 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.

The best attorney in OKC
You won’t find a better attorney. Corey knows the law like the back of his hand. He helped me so much, kelp me informed, & set my mind at ease. He has a very special presence in court, and knows how to handle himself in front of any judge. You could talk with other attorneys, but after meeting Corey, you’ll know he’s your guy. Thanks so much, Corey

Wonderful Attorney; would recommend in a heartbeat.
Our son was in a terrible situation facing 2 decades in prison. WE needed someone to fight for him. Corey believed in our son and without him, I don't believe the outcome would have been as positive, let alone, having potential reunification with family within grasp. Parents always want to do what's best for their children, and Corey helped us provide the type of support our son needed to overcome such devastating circumstances. We will be forever grateful for Corey's vigilance, advocacy, and encouragement throughout this whole ordeal. Thank you Corey. Our family is very appreciative of you and your proven ability to defend those in need.

One of the beat lawyers in Oklahoma.
Corey got me out of a sticky situation when I was dealing with a felony domestic case. I was so stress out cause I thought I would be serving time but he worked his magic and got me on a deferred sentence. He is a great attorney and I would recommend him to anyone.

Won’t let the DA bully you.
I called upon Mr Brennans help over case that surely was goin to lead me to jail time for up to 20 year over something I didn’t do. Through out the whole case me Brennan kept me updated and went above and beyond on my case. The DA kept trying to bully me into signing for jail time but Mr Brennan didn’t let that happen. After it was all said and done. Walked away with no jail time.

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 ability 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!

Professional-Hard Working and Thorough!
We reached out to Mr. Brennan as we found ourselves in a difficult position with our son who had been arrested in Oklahoma and we are from out of state. We reached out to Mr. Brennan on a Saturday and he returned our call that same day. He listened to the details we had at the time, and offered advice and what he could do based on what he knew. All I can say is that our son was facing a very challenging situation, with significant consequences. Mr. Brennan was very professional, to the point(no BS), and worked with our son on a specific mitigation plan, and provided him great counsel. This ordeal came to a positive outcome in December 2018 where my son received the best outcome possible. This was due to Mr. Brennan's hard work and dedication, along with ensuring due diligence was done as it related to evidence, lawful stop, and much more. We appreciate the work he did, and would highly recommend.

Not everything can be planned, when I needed help it needed it ASAP. I went through a list and Mr. Brennan was the one to answer the call. In fact he stayed in constant contact with me so I felt like I understood what the process was. It was also great he took time to help my husband understand.

Keen eye for the details and a constant professional
Always conducted business in a professional manner and was able to listen to everything that was happening to my family. He would take all the details and work on them and the smallest of things he would call out and question and I have no doubt that his attention to detail is a direct connection with the outcome of my case! Thank you Mr. Brennan

Tough and thorough
From the beginning of my case, Corey was hard working, thorough, and honest with me about all possibilities. His experience with a variety of cases, knowledge of the law, and experience in many different courtrooms gave him an excellent knowledge base for my particular situation. He was tough and reached the best solution for my case.

Erroneous VPO vacated
I am a small business owner who also does a lot of volunteer work who found myself being served a VPO by a vindictive business located next to my residence. I call Mr. Brennan and explained my situation to him. He immediately saw through paperwork that I was given that first I was not served with a proper notice of court date and because of this, she was given a default judgement. Me. Brennan went to work and proved that I was given improper information and we were given a new date to fight in court. Our court date came and he had done his homework on what was a pack of lies and proceeded to prove she was wrong with every accusation and the erroneous VPO was immediately vacated without our side even having to call a witness. Me. Brennan was born to be a trial lawyer! If ever you need an attorney, he should ALWAYS be your first phone call.

Best criminal defense attorney in OKC
Cory took my case on a probation violation that I didn’t even know I had till they picked me up. Cory researched everything, went to battle for me when the courts were inaccurate. He had me do some pre court classes and such in advance so that the outcome would be in my favor. Not one time did he judge me or look down on me. In the end, I did absolutely no time and he got me just 2 years of probation. I gained a friend and have recommended him to others. This is one attorney that I will never lose contact with. He will fight for you till the end.

Life saver
I had a very serious felony assault case trailed by multiple misdemeanor charges. I had no idea how I was gonna handle it or how bad the outcome would be. When Mr. Brennan took on my case he made me feel better about the outlook as well as gave me great advice. Financially I wasn't stable and feared how things would turn out and When things didn't look good for me he turned things around and got my felony assault dropped to a disturbing the peace misdemeanor on a deffered sentence and now I have a second chance to do great things. After my case was handled he helped me set up my payment with the court clerk as well as going to the DA office and setting up them. Not only did he save me from my own terrible actions but after everything was over he gave me some great life advice and motivation to do things differently. He always had positive and supportive things to say as well as make you laugh. I would HIGHLY suggest him for your case

Excellent attorney
My case was one that made me fear for my future as the accusations made toward me were extremely serious. Mr Brennan always reassured me that all would be well. Mr Brennan made me feel comfortable and gave me much needed hope. If i had any question, Mr Brennan always had an answer. Mr Brennan was more than willingly to travel the distance to handle my case. I highly recommend Mr Brennan to anyone.
