About Jason

Learn Jason’s areas of practice.

Hi Folks, and thank you for taking a look at my profile.  I've been practicing personal injury and employment litigation since I graduated from law school. I only represent individuals and have never represented big insurance companies or employers.  I love what I do and I love helping others when times get tough.  I give all my clients my cell phone number and I'm available 24/7 for them.  If you have a legal problem feel free to give me a call.  If I can't help you I will put you in touch with the best lawyer I know on the subject.  Thanks.

Car accident case
From the beginning of this case (back in May of 2015) I was able to get advice from Jason up to now. I was in a car accident and was not at fault. Once I was able to talk to Jason, he was able to help me out immediately and took action towards my case. Throughout the whole year of paper work, phone calls, signing papers, etc. I was patient enough until the end. Once the case was over, I was able to get my sharing with getting a better car and able to pay for my medical bills. I recommend this attorny to anyone!!

I was dreading the arduous and bureaucratic process of filing a lawsuit, but Jason and his staff were so professional and efficient, they helped the procedure go very smoothly. Jason has extensive experience in private practice, which gives him a thorough understanding of the entire judicial process. From your first conversation with Jason, you immediately become aware of his integrity and commitment, and moreover, the passion he exudes for his work. Any concern I raised was immediately addressed. Phone calls were answered in a timely manner. Information I requested about the process was promptly forwarded. And there was never a complaint from his staff. They were always courteous and attentive, making me feel that my case was the only one being handled by the firm, when in reality I was likely one of hundreds of clients. . It is that which distinguishes Jason's firm from the rest and he genuinely cares about his clients, which is further evidence of his dedication and wonderful service.

Superior Representation by Jason A. Charpentier
Upon having experience in the St. Louis County Court system, I was fortunate to acquire the representation of Jason Charpentier, on a very complicated case. With ultimate confidence, I would recommend Jason, as an Attorney with superior abilities to handle and instinctively & successfully assess a case. He carefully evaluated the criteria & issues promptly in deciding initially to be retained, & with great care, confidentiality, knowledge & precision continued to study & consider all the issues in preparing & representing the case with the end result being successful. Jason's law firm & legal staff were very professional & expeditious, and pleasant to deal with, in what could have been a very stressful situation. I was always kept informed, and any time I called to inquire on any issues, I was given specific information of what to expect, and time frame of when I would receive answers to my questions. I never had any doubt whether my case was continually being worked on, always felt it was priority, by the communication with Jason and his staff. I observed in the office, when I had appointments that all clients were treated with the same respect and expeditious manner. In the future, I will continue to rely on representation or advice if needed, & without doubt direct any recommendations to others, to Jason A. Charpentier, with upmost confidence in his abilities & superior capabilities which he exhibits as a #1 Attorney in St. Louis!!!

Exceeded my expectations
Jason was great. He was realistic about my case and surprised me with the amount of the settlement. Never had a problem getting in touch with him. He even talked to me while he was on vacation. I would recommend him to anyone for a serious injury or employment case.

Best lawyer I've ever had, hands down.
I've never really needed legal aid in my life, but when I went through a devastating time, Jason and his legal aids were right there to help me. This has been a really hard a trying time for my family, and Jason has done nothing but be there for us on a legal side, as well as a friend side. He does more than just help, he goes the extra mile to make sure that I am getting everything that I need out of my lawsuit. You can't help the people in the world, or what happens to you, but I know that Jason will always be my go to person if I ever need legal help. Best lawyer, as well as a great person who has his clients best interests at heart.

Jason was fantastic!
Jason was fantastic. He gave me his cell number when the case started and I never had a problem getting in touch with him. He was up front with me about his opinion of my case and delivered as promised. I would recommend him to anyone.

Trusted, Knowledgeable Attorney, you can count on... to WIN!
My experience with Jason & his team at Growe Eisen Karlen, was phenomenal. He handled a very complicated Employment/Personal Injury case for me. He "held my hand" through out the entire process. He made sure that any question or concern I had through out the process, was answered. He guided the way before, during, & after any legal proceeding. He not only Won & Settled my case... but did so, with out ever stepping foot into a court room. I recommend his services & Firm, to everyone with any legal needs.
