Client Reviews

"Mr. Lukehart is simply THE BEST! I have a child with special needs and we have struggled with issues surrounding his care nearly the entire nine years of his little life. I was lost and had many questions, and frankly just tired of packing up and moving instead of facing the unlawful discrimination. Mr. Lukehart provided me with an immediate response and gave me comfort that there are good people out there willing to go that extra mile. Mr. Lukehart is all you will ever need in an attorney. Thank you for supporting us!"
