Tom Hill has been in the fitness industry since 1998. His intense dedication to fitness began at a young age. Tom was given a gift that allowed him to succeed in athletics and fitness. At a young age, Tom became recognized as a 3 time New Jersey state wrestling champion. Tom was also recognized for his baseball talents at state and national levels. Dedicated to making the most of his ability, he knew training and nutrition would be the biggest supporter for his success. After noticing the difference fitness has on his success and life, Tom wanted to use his gift and knowledge to help others achieve their fitness goals.

Over the past 15 years, Tom has trained and studied under many highly trained coaches in various areas of expertise. Having the opportunity to train and study under these coaches gave Tom the skills necessary to succeed and be an effective gym owner and coach himself. Tom has a strong background in speed and agility training, powerlifting, Olympic style lifting, kettlebells, gymnastics, and sports specific training, as well as, sports specific nutrition. Tom’s experience includes having worked with Professional UFC fighters, World Champion Jiu-Jitsu competitors, Professional football and baseball players, American Rugby athletes, and high school wrestling and baseball teams. Tom’s experience has provided him expertise in athletic training and preparation. Tom’s approach to CrossFit is different from that of most CrossFit gym owners.

Tom’s athletic theory is based upon a different, more advanced philosophy. It is based upon years of research and training various athletes, including his experience as a catcher on the Kansas City Royals. Tom’s model concentrates on enhanced athletic performance. He believes performance is not measured by skills practiced in sports, but by the development of physical elements such as speed, strength, agility, quickness, balance, and power. After experiencing first hand the results of a balanced Strength and Conditioning program, combined with Mobility, and Nutrition, he strongly believes that these three components are the key to success. If one of these three components is missing the results a person is looking to achieve can be greatly affected and in the long run can lead to imbalances and injury. Tom has taken this belief and transformed it into the cornerstone of CrossFit ATR.

At CrossFit ATR every client that walks through the door is provided with the knowledge of the proper movement patterns of each lift, an in depth breakdown of the mobility and range of motion issues based on their skills and ability, along with the knowledge to correct those issues.

Providing our client’s with this knowledge significantly increases our client’s ability to achieve their goals. Tom’s common quote says it all, “You tell me your goal. I’ll show you the path. Together we can accomplish anything”.

Sean Ryan

CrossFit Coach

A native to San Diego he was born and raised in east county and went to San Diego State to get his bachelors in psychology specifically in behavioral health. Through high school and college Sean always had an interest in physical movement specifically powerlifting and bodybuilding that changed with a severe car accident that limited his ability to perform the activities that he loved and as a result he began practicing yoga. Through yoga and mobility exercises he was able to regain his strength and range of motion from his previous injuries and shortly thereafter got his certification as a yoga instructor. at the same time Sean became a yoga instructor he also found CrossFit and was immediately hooked. After two years of being a student of CrossFit Sean began crossing over his yoga and mobility techniques on to his CrossFit students using techniques he had learned through yoga teacher training and mobility exercises to improve their range of motion and posture to make them better and safer CrossFit athletes. From the beginning student who has never even performed an air squat to an advanced athlete, becoming more flexible, mobile, and stable and in better alignment will improve any athletes’ performance and dramatically reduce the chances of having an injury because of improper positioning in a lift or movement. This is Sean’s main concern and also his passion when working with athletes.
