TJ hails from New Jersey. Those who know him best would say that the Jersey in him makes for some of the most appealing aspects of his character, including a powerhouse work ethic and an ability to relate effortlessly to people from all walks of life. A lifelong athlete who took time to grow into his large physical frame and excel at sports, TJ has always had a foot in the fitness realm. After college, he taught PE at a school in his hometown. While he liked the job, he decided there was more to explore; he moved west, landing in Marin County in 1992. After many years as a personal trainer, TJ opened his own gym in San Rafael in 2002, shortly before the birth of his first daughter. At that time, it was a place where he and other personal trainers could work with clients without the hassles of larger, less personal facilities.

While TJ loved his work as a personal trainer, by 2007 he found himself itching to expand his knowledge and recharge his training batteries. This happened when he found CrossFit, an exercise program involving functional body movements executed at high intensity and with great variety. TJ took to CrossFit immediately, immersing himself in the science and theory of the program while introducing his clients to their application. TJ, himself, began training with the CrossFit program and quickly saw and felt results that he had never experienced in all of his years of exercising. He shed body fat, increased his strength, lowered his running times, and, perhaps most importantly, got rid of chronic knee problems and high cholesterol levels. TJ combined CrossFit with aspects of other strength-and-conditioning and nutrition programs he holds dear, a holistic approach he still uses today and one that is manfested in all of TJ's Gyms.

Like that of many small business owners, TJ’s success can be attributed to a number of factors. However, those closest to him emphasize the same interpersonal qualities that allowed him to retain his first clients over 25 years ago. Although TJ holds certifications in various aspects of fitness training, he finds that it is his independent learning that has been most applicable to the success of his gyms. A driven researcher, TJ's goal is to constantly delve into smart science behind fitness, health, medicine, nutrition, psychology, in order to adapt and innovate for the benefit of his members. His passion is helping people set goals, stay accountable, and lead better lives. He meets individually with everyone who walks through the doors of the gyms, a practice reflecting his deep desire to connect with each of his members and help them succeed in their fitness and lifestyle goals.

TJ feels fortunate to mentor and work with other fitness professionals who love their jobs and bring their own personalities and interests to his gym. He is most proud of the amazing community of people he and Allison have been fortunate enough to bring together at TJ’s Gym. While life is sometimes stressful and always very busy, TJ is inspired by the athletes in his classes, her personal coaching clients, and the daily opportunities he has to help people live longer, more fulfilling lives.

Susan Headshot.jpg



Susan walked into TJ’s Gym at the original Corte Madera location in the early Spring of 2011. She was inspired to experience CrossFit, after witnessing the total transformation of two close friends who were moms at her kids’ school. After one summer at TJ’s Gym, these moms had transformed themselves into people confidently wearing skinny jeans and backless dresses – something Susan wanted for herself badly. They also carried themselves with confidence and spoke of their newfound strength and confidence, which was even more impressive. Having attempted many different ways to “get thin” and fit through poor diets, cleanses, group exercise classes, and memberships at swanky gyms, Susan hadn’t found anything that worked, until she found TJ's Gym and CrossFit.

Susan is no stranger to training, competing, and coaching. A former NCAA Division 1 volleyball player at St. Mary’s College in Moraga, CA, Susan later played for an International traveling team through her post-college years. She began her career in the fitness industry in the mid-90s as a personal trainer in San Francisco but put it on hold to pursue other endeavors, including staying at home with her young children. In CrossFit, Susan finally found her “thing.” Inspired by the physical work in the gym and the emphasis on nutrition, she dug in deep and even had her own food blog for some time. Susan has extensive knowledge about nutrition and cooking and is always good for a tip or two!

Susan is thrilled to be helping members to achieve their health and fitness goals and change their lives for the better!

In college, she played NCAA Division 1 tennis at Colorado State University in Fort Collins, Colorado, her home state.

Veronika happened upon CrossFit™ in June 2012, towards the end of her college tennis career. It was a perfect transition for her, as she was looking for something to keep her in shape and allow for a competitive outlet. Veronika has put that competitive fire to work in CrossFit™, competing on a Regionals team in 2014 and 2015 with her previous gym in Colorado, and in 2016 and 2017 with TJ's Gym. She gravitates most to gymnastics movements, given her history in the sport, and she is a great resource for TJ's Gym athletes wanting to develop their skills in this aspect of their fitness.

Prior to beginning work full-time at TJ’s gym, Veronika worked full-time at Puori, a supplement company, and she has significant knowledge in the area of supplementation and nutrition.

Zoe Coach.jpg

zoe ades


Zoe is a Marin County native who is passionate about all things fitness and health. She grew up loving athletics, playing softball and basketball at Marin Catholic ('08). Softball was her main focus, and she played competitively until her lack of strength training and overuse led to a substantial shoulder injury. She had big plans to play softball for UC Davis, but the shoulder injury ended her softball prematurely. The injury was a huge blow to her identity, and she struggled to find something to replicate the athletic community she missed so much. She loved working out and feeling fit, but daily trips to the gym quickly felt redundant and uninspiring.

In 2012, a friend brought Zoe to her first CrossFit class in Davis, and she was hooked. She immediately felt the benefits of the lifestyle and community fostered by the workouts. And it was a bonus that solid nutrition and a happy life were encouraged! Her shoulder injury responded quite well to the strength training involved, and Zoe knew that she was on track for her future. Zoe landed at TJ's Gym in the summer of 2014. Soon after, she received her Level 1 CrossFit certification and began training to compete as part of the TJ's Gym team. Zoe loves that she is challenged every day, and she is continually inspired by the significant and positive changes that can happen when clients join the gym.

Outside of the gym, Zoe enjoys exploring the outdoors with her dog, Tucker, and completing insane physical challenges like the GoRuck.

Zoe is passionate about her current path and her goal is to help people create happiness through fitness and health.
