Geoff Guilfoy

“People are the heart and spirit of all that counts.” 
- Max DePree, author and founder of Herman Miller Office Furniture

“Leadership is about people and the intimate, intricate relationships between them.” 
- Chuck Ferguson, Indomitable Spirit: Life Changing Lessons in Leadership

“Being a leader changes everything. Before you are a leader, success is all about you. Nothing you do anymore as an individual matters except how you nurture and support your team and help its members increase their self-confidence. Put another way: Your success as a leader will come not from what you do but from the reflected glory of your team.”
 -Jack Welch, former CEO of General Electric
