Justin has been very supportive and on point with my legal issues. He's taken the time to understand my needs and requirements and put them into action. He's super responsive – normally hear from him that same day or even sooner when I reach out to him. He's down to earth and easy to talk to. I also think he's one of the smartest lawyers in practice. He's been extremely fair in all of this as well. I highly recommend him and the entire Coon and Cole law firm


Mr. Aronson represented both my business and me personally. He was always expertly prepared and ready for each event. He is extremely knowledgeable of the law. His preparation and counsel led to a good outcome. Highly recommend.
