Expert in Brain Injury Litigation!
Words cannot begin to express how appreciative we are to Mr. Casper. He has become like family to us. Not only has he worked diligently to get the results we had hoped for, he also genuinely cares for our family. Mr. Casper was fully prepared for litigation. He spent countless hours researching and preparing for the lengthy trial process that we all had to endure. More importantly, he made sure that our family was prepared! Mr. Casper is well versed in brain injury and is in tune with the needs of our brain injured son and our family. We would recommend Mr. Casper and his firm to anyone who needs his assistance! He is intelligent, well mannered, very thoughtful and accomplished more for us than we expected!

Employment Case
“Ari Casper is not only an amazing attorney, he is also an honest, caring, and compassionate person. He represented me in a case involving an employment situation and he went above and beyond to help me in this very difficult, emotional time. For that I will be forever grateful. He is very dedicated to his work, clients and his cases, He was always available when I needed to speak to him, he got me better then what I had expected for results, he listens to you when you speak so your not repeating yourself over and over when you meet. I find people don't' listen now a days to what your saying, he listens ,he cares. he sees you as a human being and isn't just an ambulance chaser. I couldn't have asked for a better attorney. I am so grateful to you. You did an amazing job Ari and I highly recommend you and wouldn't think twice to call if I needed you again. Thank you so much!!!
