I was born with an insatiable desire to learn and share what I learn with others. This has led me down many paths some more fruitful than others. Even before I officially started coaching in 1994, I was already on the fast track with personal and professional development. I invested in myself and studied with thought leaders, coaches, therapist, shamans, sages, and mystics. Although, I learned somethings that were useful I always felt like there was something missing.
