Attorney Jamison Allen

Trial attorney Jamison Allen is best known for obtaining a $3,000,000 verdict for an injured 93-year-old plaintiff in August 2022. Two mediators had evaluated the case in mid six-figures, but Jamison’s client was determined to seek full justice. The verdict has been used by elderly plaintiffs across Indiana to increase settlement offers because now insurance companies know that even Hoosier plaintiffs over 90 years old can obtain 7-figure verdicts. Jamison was the lead attorney in the case from start to finish. In addition, Jamison is also in an exclusive group of plaintiff injury attorneys who have prevailed in an Indiana Supreme Court case. He proudly second-chaired and drafted significant portions of the appellate briefs in Clark v. Mattar, 148 N.E.3d. 220 (Ind. 2020), the case confirming that a potential juror who rejects the concept of non-economic damages should be removed for cause.

Attorney Allen helps injured Hoosiers hold insurance companies and corporations responsible. Attorney Allen’s skills were sharpened with knowledge he gained as an insurance company attorney, and he knows how to protect his clients from the insurance companies’ strategies. He has litigated jury trials across Indiana and represented clients before the Indiana Court of Appeals and the Indiana Supreme Court.

Born and raised in Indiana, he graduated from Indiana State University with a double-major in social studies education and theater, as well as a minor in history. Jamison then obtained his J.D. from the University of Illinois College of Law in 2002. Jamison is active in many community organizations with his wife and three daughters.

– Donita M., September 2022

“After our accident we knew that we needed an injury attorney, but we had no idea where to turn.  The pushy car salesman attorneys that we saw on television were the last thing that we wanted to deal with at that time.  I turned to my lawyer friends for suggestions and Jamison was the first recommendation I received.

Jamison has been consistently professional, straightforward and transparent when dealing with our case.  He kept us updated throughout the entire process and was always a text or call away if we had a question. In particular, explaining in layman terms the legal jargon of documents. Charity was also quick to respond if we had questions or needed consultation.

Having Jamison on our team really did help to make the best out of an unfortunate situation.”

– Marcella M., August 2022

“Marc Lopez Law firm has exceptional people working there. Attorney Jamison  Allan and Charity worked diligently on my case. They were great with follow thru and returning phone calls and emails quickly. I was very pleased with them and the outcome of my case.”
