Stephanie Sharp Stephanie Sharp comes to Crossfit Marin with a passion for coaching that is unwavering. She grew up competing in regional gymnastics and dance competitions and discovered weightlifting at 15 years old. By 16, she was the only female in her school to pass the Marine Corps fitness test at the male-prescribed fitness level. She couldn't have known it then, but CrossFit was her destiny. After spending years in the corporate world, Stephanie decided to try working in the field of her passion and became a personal trainer. When Stephanie became exposed to CrossFit, she was hooked and knew that CrossFit was the only way to provide her clients with the type of holistic fitness that they needed and deserved. When she isn't training private clients or punishing the minions of CrossFit Marin, she is volunteering with Big Brothers Big Sisters of Marin and spending precious time with her friends and family.

Sarah Farrell Sarah has been a personal trainer since 1997. Her initial intent was to train people as an interim job until she decided what she really wanted to do. She very quickly discovered that training people is exactly what she wanted to do. She has long term clients that have been working with her for a decade. Her training goes beyond just fitness. She has helped people discover not only physical strength, but personal strengths. She has helped many people transform not only their bodies but their vision, beliefs, preconceptions... about themselves. She has several clients with maintained weight loss of over 50 lbs, and one with over 100 lbs. This all through true long term transformation, not short term quick fixes. Her focus continues to be on truly helping people become healthier, more active people leading to a more enjoyable life. "I love when I see someone's confidence develop and when the ability to take on a challenge in a workout extends into the rest of their life. My goal as a trainer is to help people learn to believe in themselves and to find out how strong, capable, and resilient they truly are." - Sarah Farrell Level 1 CrossFit Certification CrossFit Nutrition Certification Contact Sarah
