“I had the fortunate opportunity to work with Sean Casey at the Athlete’s Performance Institute. While coaching, Sean demonstrated a strong work ethic and a desire for perfection. Sean’s knowledge of multiple training methods helped prepare me for that season. His greatest concern was making his athletes better each day.”

“Sean was a positive influence on our student-athletes and the Strength and Conditioning Department at UW-Madison. He is a bright, innovative thinker and always looking for ways to improve the performance of the clients he works with, regardless of their starting skill level.”

“Sean Casey is a true example of passion, consistency, and excellence. I had the pleasure of first meeting Sean in 2016 when I was a swimmer preparing for the collegiate D1 level. Sean at that time was our strength and conditioning coach as well as our dietician. Understanding the gift that he was to me and the team only grows as the years go on. His unique ability to connect with all ages, backgrounds, and skillsets to support each individual and team’s journey towards the next level is undoubtedly his greatest strength. The athletic and kinesthetic understanding of specific needs of athletes is really world class. Then, combining his greater than 15 years of experience in the dietary/health industry really completes the picture. He was always very clear. If you’re not putting the right fuel in the engine, you will never find out what you are truly capable of. He has been a resource to me far far past my time as an athlete and I am sure that each endeavor he choses to pursue will yield results in the highest degree.”

“I first knew Sean Casey from the excellent articles he posted on the internet. He clearly knew what he was talking about, both with regard to training and to nutrition. His research was always sound and the fact that he always quoted his sources, further increased my esteem. When I needed advice on my nutrition, Sean was the obvious choice. Still, I had some doubts if even he could help me. I am a middle-aged, competing weightlifter from Europe, who suffers from a digestive disorder; not exactly your typical college aged athlete.”

“Sean exceeded my expectations. He studied my training schedule, food intake, medications and came up with a dietary program that exactly fitted my needs. He taught me the principles of what to eat and when. My meals now fuel my workouts and my supplements no longer conflict with my medications. To make things easier, Sean even took the trouble to convert everything to metrics for me. Since I’ve started to work with Sean, I am fitter and stronger than I ever was and haven’t gained any weight despite eating more food.”

“I am very lucky to have worked with Sean. If you’re serious about your performance, I can recommend no one better.”

“Sean Casey serves Ethic Sports Performance as our Director of Sports Nutrition. His expertise in nutrition, supplementation and holistic health is second to none. Having a pedigree in strength & conditioning also gives him a big picture view of performance at large. He is a brilliant yet pragmatic resource for our community and I am equally proud to call him a trusted colleague and friend.”
