Jason Sheasby Justice ImageA typical day for Jason Sheasby can vary widely. Many of his cases are on the East Coast, so he must get up early in order to communicate with them and get a head start on his work. Jason is a morning person, so he enjoys working in the quiet hours before his family gets up. Every morning Jason helps his two daughters get ready for school, and then he returns to his work. Besides communicating with clients, he conducts research, writes, and meets with industry experts—all of which help him put together a strong case for each client.

With every case, Jason believes that it’s essential to put aside any set presumptions. Jason’s goal is to let the knowledge take him wherever is necessary, which is difficult to accomplish with a closed attitude. Each client, as well as each case, is different, so the approach to each situation should be different. Jason’s open attitude has helped him learn a lot over the years. Plus it keeps the work exciting and fun.

When Jason is not working he enjoys cooking, spending time with his family, and walking his dog.
