“I have been competing in Snowboard Cross for 20+ years and have been exposed to many different forms of training, both physical and mental. After working with Denise, I felt more comfortable with my emotions because I could understand what they were doing to my body, and determine if was positive or negative. Understanding how I was reacting to my emotions, allowed me to anticipate the impact they could have on my body and learn how to make them work in my favor.
