Hired Attorney Mark G. Griffin

After tirelessly trying to resolve a complex real estate issue on my own for 19+ days, I retained Luke’s services and he had the matter fully resolved within literally one hour which far exceeded any of my expectations. We would not have been able to close on our family’s dream home for our four young children and aging parents without his expertise, professionalism, and compassion. Luke's depth of legal knowledge was matched with genuine kindness and determination. He made what felt like an impossible situation completely manageable. I cannot recommend him highly enough. He is an outstanding attorney and a true problem-solver.
