  • Angelo Sisco

    Owner, Head Coach

    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

    Head Coach, Nutrition Coach

    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.

  • Zach Riberdy

    Coach

    Zach comes from a family of coaches with a high-level of success and passion. Although Zach played many sports, including Division II basketball and baseball in college, he didn’t feel the connection to those sports as his grandfather, father, and uncle did. When he found CrossFit in 2013, he was instantly drawn to the power, agility and grace the Games level athletes possessed. As a coach, he desires that type of athleticism for the members of O’Hare CrossFit, and for himself as an athlete. Coaching is a give and take relationship for Zach, he draws the same motivation from the community as he hopes to provide.

  • Ernesto Martinez

    Coach

    Ernesto started CrossFit when a few of his friends introduced him to O’Hare CrossFit. Although he played sports all his life, he was never consistent when it came to working out in the traditional way. CrossFit changed how he looked at fitness and working out. Today, he is passionate about helping others achieve what they believe to be the impossible.

    Certifications:

    • CrossFit L-1
  • Matt Tierney

    Coach

    Matt was a collegiate football player, and has dabbled in amateur MMA and boxing. In his training, Matt wasn’t excited about the typical gym routines. He tried CrossFit after watching a few videos and from that first bewildering workout, he was hooked. Today, Matt dedicates his time to the sport of CrossFit as and athlete and a coach. What he really enjoys about coaching is introducing newbies who are hesitant to try something new and different by making their first workouts fun and exciting — but he’s sure to make the workouts tough in the way it makes people come back for more.

  • Susie Castro

    Coach

    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 discover the power within themselves.
