Client Testimonial

“Gregg coached me for 4 months when I was navigating a massive transition in my career. I am so grateful to have worked with him as my coach. Gregg has a way of being that allowed me to be vulnerable in our coaching sessions and explore what was possible. In between coaching sessions, he would always connect with me in some way that supported my continued growth and showed me that he cared about me as a person. I would work with Gregg as my coach again!”
