For Angelo, coaching is his life’s work. He has faced hardship when it came to his own health and fitness. He managed to turn his life around, and continues to make progress. Towards the start of his fitness journey, Angelo dedicated himself to losing weight. He went on to lose 100 lbs in 7 months with CrossFit and proper nutrition. During this time, he found a passion for motivating others to pursue their fitness goals, and aspired to become a trainer. He quickly found that the environment of the hard-sell and peddling supplements was not the approach he wanted to take, but instead, wanted to provide a valuable, sustainable service — in the same way that he worked toward his personal fitness goals. Fast forward, and today he is proud to call O’Hare CrossFit his home, where anyone who is looking for a change, and willing to put in the work is welcomed into a supportive community.

Becca Chilczenkowski


Becca was an athlete throughout her youth, playing soccer and basketball then going on to receive All American Honors in soccer in college. After her collegiate career came to an end, there was an element missing in her life that fulfilled her competitive side until she found CrossFit. She knew it was something she wanted to be better at and gave it everything she had from the first day. CrossFit made such an impact in her life that she hopes to provide others with the same positive, life-fulfilling experience she had. Becca loves food and has a passion for nutrition. Through CrossFit and nutrition coaching, she hopes to provide her athletes with the opportunity to feel their very best.

Susie Castro


Susie was never an athlete in any sense of the word. Preferring to play it safe throughout her school years she discovered running as a form of exercise and an outlet for stress as an adult. After countless years and many races, she grew bored of the monotony that came from running and at the insistence of her brother decided to give O’Hare CrossFit a try. Since then she has never looked back and has gained strength she never thought possible and discovered resilience within herself. She is now excited to be able to help athletes as a coach so they can find the power within themselves.

Zack Jankiewicz


Zack was an athlete ever since his days of tee-ball. Growing up he played all types of sports, but eventually found his love for football and made it his sport in high school. Through football, Zack was introduced to weightlifting and took a liking to it quickly. After getting caught in a rut in college with the same old bodybuilding and weightlifting, Zack found CrossFit one summer and was hooked immediately.

Watching videos of CrossFit, he never thought he would be able to do some of the high-skill gymnastic movements, but three and a half years later, he is. Continually improving and looking for new ways to get better, you can find Zack in the gym most days working out himself if he isn’t coaching. CrossFit opened his eyes to a type of fitness that can last a lifetime knowing there is always ways to improve. The lifetime of improvement through CrossFit is one of the reasons he got into coaching because it allows him to help people stay active and live a healthy life no matter what age you may be.
