I was involved in a MVA 5 ½ years ago. I had no clue what to do after the fact because of my injuries. Someone had referred me to Frank and Lesly to see if they could help me. And I am so greatfull I did. They took everything over, were able to get me all in home support, rehab etc. I would not be where I am today if it wasn’t for them. They were always there to answer my questions, time and time again when I couldn’t understand what was happening. Kathy always answering my emails to help me through all the process. They were always upfront and honest about what to expect, and what they could do to help me. If you are looking for an amazing legal team you have found it with them! – C.M.

Worked with Frank and Lesly and their team for almost 6 years. They made us feel we where their only clients with the level of service and compassion they provided. If we had any questions we always got our answers that promptly. Their ability to work with someone with a invisible disability and adapting to the persons needs was amazing. Totally recommend this law firm – D.C.

When I first approached the law firm I was a complete and utter mess physically. I truly had no control over events in my life. THE REGULAR activities of daily living WERE overwhelming. Frank and Rebecca provided reassurance and security. Knowing they were only a phone call away gave me confidence and a relieved feeling because I knew I had their support and was able to focus solely on rehabilitation. As my health improved during rehabilitation, they provided me with more insight into my case. That insight gave me strength and formed the foundation of my settlement. Years later, I see it was truly a team approach. They listened. They understood that the accident did not just affect me but also my family as a whole. I believe the best compliment one can give is a referral. – R.B.
