Client Reviews

Bisnar Chase Review - Natalie

I’m so impressed with this law firm. I lost my mother because of a seat defect when she was rear-ended in an auto accident and Bisnar Chase stepped up and took our case. The staff is wonderful and Brian Chase took his time explaining everything via phone with me. I’m honored to have the best of the best working on our family’s behalf, trying to get justice for my Mom, because of a negligent car company still manufacturing faulty seats. I look forward to working with this firm and am hopeful for a positive outcome. Thank you so much, Brian Chase. I know you will work your hardest on this case. God Bless you.

Great people in this office, everyone was really helpful explaining everything. I was referred by my aunt for my car accident in October and the case went pretty fast. No problems and very professional. I was kept in the loop thru the whole process and was able to get a better settlement than my insurance company said I would. I can’t really compare them to other law firms because it was the first time I had to use an attorney, but my bad experience with the car accident was handled as well as I could have hoped.
