About the Founders

David and Lex started Physiology First in 2019 to take a stand in the face of rising youth anxiety rates.  As co-hosts of the live talk show, The Weekly Brain Freeze, they share the science of the mind, body, and brain on the airwaves on a weekly basis. David and Lex co-own a performance training center, The Distance Project, in Freeport, Maine where they train athletes from 5 years old to 85 years old. Both David and Lex are avid athletes and passionate learners about all things health, fitness, and physiology. In 2018 they founded a consulting business, Breathe to Perform, specializing on bringing breath education to companies, organizations, schools, and teams. David is the author of the book Breathe to Perform: Simple Exercises to Reduce Stress, Improve Energy, and Peak Athletic Performance. Lex is a PhD student getting her doctorate in Physical Therapy and planning a second doctorate degree in neuroscience. Through partnerships in science, medicine, and education David and Lex are on a shared mission to change the way that we learn about our bodies by putting physiology based learning at the foundation of education.
