Client Reviews

Lexi P. – December 2023

Elk & Elk took great care of my grandmother after her life-altering car crash. John O’Neil went above and beyond to help my grandparents understand the process and they were able to fully trust his expertise. John’s staff also provided extra help in accounting for my grandparents’ lack of technology and understanding – which was invaluable. The case resolved faster than we could have imagined, our family is very grateful to Elk & Elk for their support.
