    I endorse this lawyer. Mark is hardworking, dedicated, tenacious, ethical, and will put in the needed time to do a job right. I respect Mark and find him thorough, thoughtful, good with clients, fair, and can be a bull dog when needed. I have given mark several referrals with complete confidence and worked on two cases with him. I find him to be cooperative and a team player.
