Mark's desire to make a difference extends to his role as a Wish Granter, his work with Junior Achievement, his support of Children's Mercy Hospital, Big Brother's Big Sister's, and the MMF Foundation to name but a few.  He is blessed with three incredible children, Lauren, Mollieanne, and Mason.  He shares his vision and passion for making a difference in the world with his loving and supportive wife Felisha.  He believes the greatest influences in his life were the values instilled in him being raised in a small town in Kansas by a gentleman teacher and coach from Alabama (his father) and the sweetest First Grade teacher ever (his mother).
