“Working with Heather has changed my life. She has helped me transform my body, improve my relationship with food, and learn about the world of mindfulness and breath work. I highly recommend Heather to everyone I meet.”

“I first met Heather in San Francisco when she was one of the Bay Area’s first kickboxing instructors. Her classes were challenging but overflowing with energy and fun. Fast forward many years later and she is getting me in shape again with her SQUAD classes — losing unwanted weight and restoring my muscle mass, confidence and strength… and we have a great time while doing it. She has a natural talent as an athlete and fitness instructor. Her knowledge, energy, enthusiasm and dedication to her students is what makes her the #1 trainer and instructor in Northern California.”

“The first thing to know about Heather is that she is truly one of a kind. She delivers an incredibly rare combination of deep fitness knowledge, dynamic and highly effective full-body workouts, and a positive, uplifting spirit that remains grounded and so very motivating. "Push through this last one, or listen to your body and take a breather!" It is a judgement-free space, and Heather is truly masterful at leading a group class with a nurturing intensity. In fact, I've never enjoyed group fitness until I discovered Heather's practice. It is so apparent from day one that, above all, Heather cares about cultivating a supportive community. I cannot recommend Heather enough–join the squad!
