Steven Burroughs Jr Founder, Aeon Wellness Club

Working with Daniel has been extremely impactful in the development of our performance and longevity services. He not only guided us through the selection and acquisition of our metabolic testing equipment, but also provided comprehensive staff training to ensure our team delivers accurate, consistent, and meaningful assessments. For over five years, he has been a trusted educator and mentor—helping deepen our understanding of the metabolic systems, how to properly assess each, and how to design training strategies that drive real improvement. Today, he continues that legacy by working closely with our lead metabolic technician, elevating the standard of metabolic education and application inside our facility. Professional, knowledgeable, and genuinely inspiring--- he brings clarity to complex science and turns it into actionable systems that benefit both coaches and members. His influence is embedded in the foundation of how we approach metabolic optimization, and we are grateful to have him as a long-term partner in our mission.

Debbie Potts The WHOLESTIC Method Program Fat Loss

I first learned about Daniel Crumback in a Metabolic Analysis Expert certification online course and right away I knew I could trust his recommendations based on scientific evidence and his own research. Daniel has become one of my mentors as a metabolic analysis expert as I continue to learn and grow as "holistic" coach to endurance athletes and aging athletes. I continue to learn something knew on each of our mentor coaching calls and podcast recordings. Daniel is someone I trust and depend on when I need another opinion or trying to solve a problem with my own business, "The WHOLESTIC Method" investigative coaching, fitness testing and assessments.

Josef Pace Director of Rehabilitation Physio Point / Da Vinci Health

I got to know Daniel through my drive to integrate Exercise Physiology Testing in my Physiotherapy Practice in Malta. Exercise Physiology Testing is one thing, interpreting the data is another. My experience of working with Daniel has proven my understanding of the highly specialized nature of this work. I consider Daniel to be an expert in the field. His knowledge of Physiotherapy, Rehabilitation, Strength and Conditioning coupled with Exercise Physiology result interpretation makes him what I call an investigative forensic expert in human exercise physiology testing and result interpretation. Daniel can literally extract all the information necessary from the numbers and resulting graphs without having any previous knowledge or information about the case. In short, I found what I have been looking for to offer my clients that additional extra to ensure true holistic treatment, rehabilitation and sports performance enhancement.

Blaise Dubois The Running Clinic President

By teaching with Daniel at The Running Clinic, I was able to see his exceptional qualities as a communicator as well as his infinite knowledge of the science of training and musculoskeletal health. Teaching with him was pure joy. His humanity and positivism are qualities that have led me to stay in touch with him through all the years when distance and our occupations have kept us apart.
