JP Rinylo, Coach

JP is a loving father, devoted husband, and an advocate of all things healthy and fun.

Since graduating from college in ’03, he has long questioned what it means to be healthy and fit.  Through many attempts at following mainstream diets, fad supplements and popular workout programs, he has tried to attain the “look” of healthy. Having pursued all of the “quick fix” methods to getting fit and healthy, he had always failed miserably. Like many others who followed that similar path, he found minimal results and little satisfaction.

Then, a few years ago, a friend of his told him to check out a website, www.crossfit.com… and the rest is history.

The early part of his journey to finding true fitness brought him to CrossFit OTG in August, 2010. It has since led him to losing more than 20lbs,  finding a single digit body fat %, and achieving a level of fitness he didn’t think possible.

The newest leg of his journey led him to pursue a CrossFit Level 1 Certification two years ago.  Since then, he has been growing both as a person and a Coach. His approach is both technical and motivational and his knowledge encompasses each of the CrossFit movements, principles and skills. From introducing a new athlete to how their body moves, to helping a seasoned fire-breather dial in their form – he loves sharing the sport of fitness.


Sean McAvinue, Coach

Sean’s athletic background is heavily rooted in team sports during his youth which led to competing at a national level in college tennis. After his time in organized athletics came to a close, Sean’s fitness fell by the wayside as he had few training partners and nothing specific to train for. Initially “mud runs” and training for these endurance events re-sparked his interest in fitness. This new fire for fitness and a trip to Florida to visit his brother Ryan (a CrossFitter for 3 years) finally pushed Sean to give CrossFit a shot.

    Less than a year into CrossFit Sean earned his CrossFit L-1. He has since acquired an CF Olympic Lifting Cert, attended CF Coaches Prep Course, Attitude Nation Oly Cert and a Specialty clinic run by Olympic athletes in Gymnastics and Olympic Lifting. He is always pursuing additional certifications/information and is constantly educating himself on all things Health/Fitness related.  He is now currently heading up our Personal Program Design (PPD) Program
