“John fought for me like I was his own family member…”

“John Leader and his office manager Yvonne are outstanding in their profession! My case took years (8) to complete and John fought for me like I was his own family member (and won!). John made sure I was prepared to face the opposition and he supported me every step of the way. Yvonne was receptive to my every need and went out of her way to communicate information meticulously between the three of us. I would trust this team with my life, they are that good.”

“They asked the questions I didn’t know needed to be asked…”

“Leader Law Firm was exactly what I needed after my auto accident. They asked the questions I didn’t know needed to be asked and walked me through the entire process, fighting for me every step of the way. John and James made sure the healing process came first and that I was getting all of the care I needed. Though the process took over a year, they checked in with me regularly. I am very satisfied with my experience!”
