Feedback from clients I’ve worked with over the years

I’ve known Sean for many years now and he’s a very hard working guy. He’s a great trainer and really knows what he’s doing. I’d highly recommend any of my Olympic teammates and friends to him.

Sean kept me motivated while adapting exercises around my limitations. I lost substantial weight, became stronger and more flexible, and—more importantly—completely changed the way I think about health and fitness.

Few things in life turn out as publicized. One of those few is training with Sean. Sean listened to my goals, tailored training sessions to address those goals, and motivated me to train with intensity. As a result, I was physically prepared for ascents of Mt. Baker’s North Ridge, Forbidden’s West Ridge, and other trips. And he’s a great guy!

I started working with Sean when I broke my foot – making me a competitive runner that couldn’t run. He worked with me to craft a program that maintained my strength and set me up well to return to running once my foot healed. Even after I was back on the road, I continued to work with Sean, learning how to use props like medicine balls and hurdles to improve my running. My work with Sean directly paid off, and I do not hesitate in recommending him highly.

Sean O’Brien is an exceptional athlete turned trainer who understands the needs and demands of a professional, but has the knowledge, desire, and passion to work with individuals of all levels, ages, and abilities. He is creative, meticulous, and delivers an attainable, yet highly challenging workout. Sean has an excellent understanding of the human body and is committed to educating his clients while simultaneously motivating them through each individual exercise. He has traveled across the globe and brings a wealth of knowledge of different practices into his client’s routines. He mentored me both physically and emotionally through injury and I returned to the track faster than when I left. He is the most dedicated, attentive, and devoted trainer I’ve ever worked with.
