I truly appreciate the faith and confidence my clients place in me as well as the diligence of my partners and staff in ensuring the success that is expected of us. I am also especially appreciative of the support my friends and family have shown me in all that I have undertaken since I first ventured out on my own all those years ago. But most especially, I cannot express enough my eternal gratitude for the lessons my Father taught me through his life and example as small business and service station owner at the foot of Signal Mountain. Clifford Coffelt showed me what it means to not only be a good business man but more particularly what it means to be a good man and how that usually makes the difference between simply being competent vs being truly successful in what you undertake in life.”
