Being in the fitness industry for the past 18 years, Serena’s training beliefs have always been based on total body, real life movements. Serena was first certified by the NSCA (National Strength and Conditioning Academy) in 2001, when she began her career in personal training. After being introduced to CrossFit functional movements in 2011, she was intrigued and soon after, she was training in Crossfit exclusively, both for herself and for her personal training clients. Serena completed her Crossfit Level 1 Trainer Course in August 2012, continuing to spread the love of the sport to all of her athletes, and inspiring others to join her with her training. Serena then completed the Olympic Weightlifting Trainer’s Course at Foundry CrossFit in 2013, the Level 2 Coaches Prep Course a more advanced Crossfit certification, in the fall of 2014, and completed Crossfit Gymnastics Certification in September 2016 at Crossfit Costa Mesa. She started dreaming about opening her own Crossfit box in 2011, right after she began doing Crossfit, and soon after, she made that dream come true with Stellar Crossfit. Serena does all of the programming for Stellar, and is honored and humbled to have trained up all of the Crossfit coaches in Big Bear through Stellar.
