  • Darren James Quinn

    I endorse this lawyer. Mr. Garrison and I represented separate defendants in a very complex securities law matter. The trial in federal court was almost a month. Prior to and during that trial I had the opportunity to work closely with Mr. Garrison. I have participated in dozens of trials, and his trial preparation and trial skills are outstanding. The jury entered a verdict in favor of Mr. Garrison's client. On another complex matter, Mr. Garrison obtained key arbitration rulings. Thereafter I substituted in and was able to use Mr. Garrisons's rulings as a stepping stone to obtain a very large settlement.
