“I’ve been training with David for almost a year. He is excellent at programming routines that challenge me while taking into consideration my feedback. His holistic approach to training, mobility, and mental preparation has pushed me to climb at a higher level while avoiding injury.In addition, I’ve watched David coach large group classes, and he gives plenty of individual focus to those who need variations or have questions while leading high-intensity, energizing classesI would recommend David and CliffHanger Academy to anybody seeking to educate and push themselves in their fitness and mindset. David is incredibly knowledgable about mind-body performance in sports and work, and great at sharing his passion with clients.

“I met David through a charity organization and was instantly drawn to his drive,energy, and desire to help humanity become the best version of themselves! I’ve trained with David in Muay Thai and rock climbing and was astonished by the parallels he draws using these sports. I was amazed how ‘letting go from the top of those rocks’ released some ‘real life fears of really trusting myself and the people around me’ or “punching and kicking Muay Thai moves” actually released tension built up from daily stress while also providing an intense workout.’ My training sessions included leadership coaching and educating me how to overcome my personal obstacles outside of the gym. The only questions I have now are ‘Have you signed up yet?’ and ‘What are you waiting for?’ Just go for it!”

“Working with David transcends the gym. His guidance begins in the heart and infiltrates the mind. In turn, this momentum invigorates the body. By way of this approach, David has adapted his approach to strength and endurance to accommodate my struggles with a chronic illness. By combining an insistence on the breath, faith, and his ability to listen and observe my needs, David has helped to transform my identity from one of degeneration and sickness to one of power and progress. He sticks with me through thick and thin and challenges me in ways that prompt growth. It is through this dedication and compassion that David’s positive energy and guidance holds a presence in all aspects of my life.”
