Very professional, and extremely helpful. Definitely worth to at least take a free consultation because they genuinely care about people. Especially all the college kids that have no idea about law!

A Truly Exceptional Attorney - Forever Grateful for Jefferson Simmons. I cannot express enough gratitude for Jefferson Simmons and the incredible work he did on my DUI case. I came to him during one of the worst moments of my life, terrified and overwhelmed, and he immediately put me at ease. From the very first meeting, his calm confidence, professionalism, and compassion made me feel like I finally had someone in my corner who genuinely cared about my future. Jefferson is unbelievably educated, knowledgeable, and strategic. He walked me through every step of the process with clarity and patience, and his communication was exceptional - I never felt confused, rushed, or left in the dark. He always took the time to explain what was happening and what to expect, which made an incredibly stressful situation so much more manageable. Because of his hard work and expertise, the outcome of my case was far better than I ever imagined. He literally saved me from serving months in jail. I will never forget what he accomplished for me and how he treated me throughout the entire process. If you are looking for an attorney who is not only brilliant at what he does, but also compassionate, steady, and truly dedicated to his clients, look no further than Jefferson Simmons. Choosing him was the best decision I made, and I recommend him with complete confidence and gratitude.

I can't thank my defense attorney enough for the outstanding job he did on my case. From day one, he was honest, professional, and completely dedicated to fighting for the best possible outcome. His expertise and attention to detail were unmatched-and because of all his hard work all my charges were dismissed. Thank you

I highly recommend using this company. Jefferson knows what he is doing. We used Jefferson on a case where I was accused and got a ticket for 3 violations. That involved 3 accidents. He was able to fight and get the charges dropped. He has a passion for what he does and it helps us that do not know the lawyer side of things. His prices are fair for what he needs to do. Thank you Jefferson

He set our minds at easy. And knows what he is doing. My wife was charged with a hit n run, leaving the scene, and criminal speeding. The only reason she got ticketed was because the other person in the accident was a unmarked off duty fire fighter. I called Simmons on a Saturday he answered and accepted my case. He has been working my wife's case for over a year and has successfully got it dismissed. He has taking care of everything we didn't even have to step foot in the court room. He answered every call and ever text message and always reassured me. He knows the law in and out, I would hire him again. I appreciate everything you have done. I highly highly recommend you give him a call.

I had an issue with a possible charge. I was recommend to Jefferson Simmons by a civil lawyer since it turned out to be a criminal case. I wasn't sure where to go and he noticed that. Even though it wasn't something they would be able to help, he still pointed me in the right direction and guided me on my next steps. Going out of their way to help someone regardless if they can help speaks a lot on who they are. If for some reason I need help in the future I wouldn't hesitate!

I had an auto accident January 23, 2022. I was never in the position of needing an accident attorney. A lady had turned left in front of me totaling my car and injuring us 3 ladies inside. I trusted my Estate Attorney and they gave me a referral to Long & Simmons. I am glad I asked for help finding a dependable, honest and easy to deal with practice. It did take over a year to get everything handled and cleared with the other insurance companies, they don't want to let go of their money. Matt Long was very patient with me and my questions and concerns. He explained everything so that I could understand what was going on. If you ever are in need of legal representation do not hesitate to get a hold of Long & Simmons.
