Our founder

Chris Guerrero

“I LOVE the process. I love helping people see the light when it comes to the most efficient way to get healthy, and giving them the proper tools to steer their own ship. It’s the least I can do for all the fulfillment they give me.” Chris is a passionate athlete and coach who is inspired by hard work and discipline driven by passion. He aims to help his athletes improve their lives with diet, exercise, and stress management. Chris leads by example and approaches all situations, positive and negative, as an opportunity for growth. Since discovering CrossFit in 2008, he has competed at the CrossFit Games Northeast Regionals in 2010, 2011, 2012, 2013, and 2014. Along with his athletic accomplishments, Chris also opened Westchester Fit (formerly CrossFit Westchester) within a year of starting his personal CrossFit journey, taking a huge risk and leaving behind a lucrative career in banking. Today, he considers it an honor and privilege to be able to work with the hundreds of athletes that have put their trust in him to help them on their path to becoming their best selves.

Sandra McDonald coach at Westchester Fit

Sandra McDonald

Head Coach

“I love watching the progress. I love seeing people walk in the door, some unsure of what they got themselves into, and watching them surprise themselves day in and day out… If you put in the work, you reap the benefits. It’s awesome to watch.” Sandra started with CrossFit Westchester in 2010 as an athlete, and over the years has put in the work and dedication it takes to go from member to coach and leader. She is a firm believer that pursuing what interests you, what you love, showing up and getting better is what shapes your life. For her, this applies to not only her athletes but also her personal fitness and career, as she left the corporate world to take the full-time role as head coach at CrossFit Westchester White Plains. Sandra’s goal is to help people work towards meeting their full potential in and out of the gym.

Coach Co Owner Westchester Fit

“All the really exciting things in life require more courage than we currently have, a deep breath and a GIANT leap.” Mike is an accomplished athlete with a passion for working with kids and families. He enjoys getting to know the athletes, learning about their motivations and goals, and seeing them achieve more than they ever thought possible. Mike’s own life was transformed with CrossFit and CrossFit Westchester. After being a top ranked NYS Varsity swimmer, he found himself in the corporate world, out of shape, underweight and unhealthy. Since 2010, he has turned his health and fitness around by adding 30 pounds of muscle, performing better than ever, and becoming a top ranked Worldwide Beauty Fitness & Fashion Male Fitness Model.

Teaching is Steven’s main profession and he enjoys being able to carry his knowledge, experience, and passion over to the fitness and coaching aspect of his life.

Tiana Gonzalez coach at Westchester Fit

Tiana Gonzalez

Coach

“The roadblock IS the journey and you are capable of so much more than you realize. I would love to help you tap into that unknown area within yourself to discover the greatness within.” Tiana loves to work with people and is passionate about coaching athletes at CrossFit Westchester. Her love for all things related to helping people in fitness, health and wellness is what motivated her to walk away from a 6-figure salary income and promising career in 2013. For the past 22 years, Tiana has been in love with weight training and body composition change. She has transformed her own physique over the years to compete in the IFBB as a Professional Figure Athlete and passes on all that she has learned through many personal trials and tribulations to her clients. Her motto is “Never Give Up” and her tenacious attitude towards her own personal goals translates into her work with athletes of all levels. CrossFit Westchester is her 2nd home.

Karen Fraga coach at Westchester Fit

Karen Fraga

Coach

Karen started her CrossFit journey in 2014 when her older sister encouraged her to join. After seeing her sister lose weight and get strong, it was a no brainer. Karen quickly became hooked and started going to classes five days per week.
Karen loves helping others become the best version of themselves, in and out of the gym. She is currently working on a nutrition certification and hopes to help gym members with healthy eating in the future. If Karen is not eating a delicious steak, trying to perfect her Olympic lifts, or pushing/pulling a sled, you can find her in her backyard playing with her three rescue pit bulls, Emma, Lola, and Murph.
