Thank you Luke, you are amazing.
Luke McConnell is an amazing human being and an excellent defense attorney. I cannot say enough about this man and his many facets of excellence. I was facing serious felony charges that were setting me up for a minimum of 10 years and upto 30 years in prison. Unfortunately, I had initially hired an attorney that proved to be extremely incompetent, and was not able to make any headway with the prosecuting deputy district attorney. When it seemed like the walls were closing in and that I was certain to be sentenced to jail, I managed to look up Luke online where I read great reviews about his practice. I was especially pleased to find out that one of Luke's areas of criminal defense practice specialized in mental health cases which happened to be the central theme in my criminal case ( I was suffering a complete mental breakdown when I committed the crimes). I immediately switched to Luke McConnell after he heard my case and was willing to represent me. Right away in working with Luke, I noticed how extremely diligent he was in listening to what I had to say, understanding all the nuances and complexities of the case, as well as having extreme empathy and compassion for what I was going through. He truly stepped in at a time where I was extremely stressed out and practically incapable of doing anything for myself. In working with me and representing my case, he shouldered all of the burden and provided great counsel and emotional support to help me get through. Luke was methodical, well organized, and had a clear plan of how he wanted to approach the deputy district attorney and construct my defense. Luke did an amazing job and guided me every step along the way as we went from one hearing to the next in my case, each time making favorable progress in my defense. Luke was always ahead of the curve and able to anticipate all the moves made by the prosecution. In the end he was able to construct my mental health related defense and was able to provide the prosecution with the adequate documentation so as to have my charges reduce to misdemeanors. Because of Luke and his amazing defense attorney skills, I was able to avoid going to jail. I ended up receiving out of state probation as part of a plea deal with the DAs office. I would also like to add how electronically savvy Luke is- he is readily available via email and is very responsive. He quickly calls you back when you reach out to him at his office. His ease of availability puts the mind at ease. He electronically submitted supporting defense documentation to the judge ahead of my sentencing hearing so as to provide me with the opportunity to allow the judge to review favorable material without interference from the prosecution. Like I said in the beginning, Luke is an exceptional human being who is highly intelligent and has a great big heart. Even though my case is settled, we still remain in touch and he still checks in on me from time to time to make sure I am progressing well. Luke, thank you for everything you have done for my family and I- I do not have to words to express my gratitude and cannot thank you enough. I believe I have gotten a second chance at life because of you. Thank you.

Good Quality, Best Value, Professional, Responsive
I was extremely fortunate to be referred to Luke McConnell by another attorney. After our initial conversation I was reluctant to retain him since he had never filed a motion for early termination of supervised release. Finding an attorney that sincerely has your best interest at heart is extremely difficult. However, choosing Luke was the best decision I have ever made. He worked tirelessly on my behalf, stayed in constant contact by phone and email, and my motion was exceptionally represented. I genuinely believe his hard work and research was a determining factor in my motion being granted. I would highly recommend Luke for anyone's legal needs. Lee

Great lawyer for complex issues
Luke helped me navigate the complexities of my car accident case. He had to deal with multiple insurance companies and medical facilities, including legal jurisdictions. We appreciated his expertise and persistence.

He took the case when no one else would and won.
My dad was in jail for a minor parole violation and was obviously about to be sent back to prison. I begged Mr. McConnell to help us and he took the case. He asked for a continuance, had us get letters from everyone we could think of vouching for my dad's character, honesty, etc and then got the parole board to see that my father was a real person and that decision to send him back would not be appropriate in this case. Thanks to Luke, they released him.

Luke is an honest & hardworking attorney
Sure appreciated Luke's temperament from start to finish with our case. We were dealing with an absolute unrealistic opposing legal team. Luke 'ALWAYS' remained collected, professional and really knew when to put it into 4WD and win the case. This was a case where kids were involved and Luke was very compassionate and understanding. I would highly recommended Luke. He sure is a 'Rockstar' of an attorney. If you are looking for an 'HONEST' attorney that is well respected in the legal community, Luke is the guy!

Luke Mcconnell was fearless and really came through for my defense!
The law office of Luke Mcconnell was nothing but a blessing to me and my family. His attention to detail and his quick attack on the facts was the deciding factor in getting all my charges dismissed. Great attorney who really cares.

Case dismissed
Luke is a highly intelligent and skilled lawyer. It was my first time ever being involved in a criminal case and from beginning to end he made sure my case was a priority. He made sure I was comfortable with how things would proceed and completely honest about the possible outcomes. I was in the loop the entire time and never felt like my suggestions were not taken into consideration. He stayed on top of the case with the District Attorney's office to get things resolved as quickly as possible. He filed all the necessary documents so when we did sit in front of the judge for my first appearance one of the charges was dismissed before we left the courtroom. He overwhelmed the Assistant DA with the Regulatory Laws specific to my case, which resulted in the dismissal of the other charges. He fought fast and efficiently to end the situation with the best possible outcome. There was never a point throughout the entire ordeal where I doubted his abilities.

Professional and highly recommended
Luke has been a blessing for both my family and I. With an unfortunate bump in the road, Luke has been a shining star throughout a difficult experience. Not only has he put forth multiple hours with his attention to detail, but he fought for my rights in the court of law to ensure my future for both my family and I. Words cannot show enough gratitude for what Luke has done for me and I would recommend him to anyone looking for excellent representation. I look forward to using you again in the future Luke!

Won't be caught of guard
Luke McConnell joined the existing defense attorney, in my son's high profile criminal case, after proceedings had begun. Any concerns I had about that were quickly put to rest as he was able to come up to speed on the case very quickly and represented the case like he had been there from the start. Even when things were thrown his way in court that he had not be properly advised of by the prosecution, he still managed to counter those surprises quickly and effectively. With only a few moments to review the content, he was able to proceed as if he had be given weeks to prepare. His direct and cross examination techniques are very professional and effective. He is a very "matter of fact" attorney and will not waste your time. He shows compassion and relates to his clients on a personal level. When he see's that there is something wrong in the justice system, he gets involved to seek change, beyond his regular practice. I have no doubt he will succeed in improving the criminal justice system.

Sharing our experience
We had the pleasure of working with Luke who represented my husband in a complex criminal case. From day one, he was very professional, communicative and compassionate to our situation. He explained everything in detail and answered all questions completely. He turned around any calls or emails in less than 24 hrs and always kept us updated on the status of the case. He was very understanding of our family situation and demonstrated compassion making him 'humanlike' and not making us feel like we were just another case. He fought for our best interest and was very persistent with his negotiations to ensure we received the best outcome. We were completely satisfied with his work. I would recommend Luke to friends or relatives and would use him again if needed.
