The Team

Dean-Grafos
Co-Founder

Dean is a Southern California boy, born and raised in North Hollywood, CA.

At the University of California, Santa Barbara, he was on the rowing team, and often rode informally with the Cycling team on their 50-mile plus training sessions. Dean discovered the Lagree Method in 2008, and became instantly addicted. In 2009, Dean began opening studios with his wife, Lisa. Bringing the gift of health to so many people is incredibly satisfying. When he is not teaching classes between San Diego and San Francisco, Dean loves travel adventures and spending time with his beautiful wife and daughter.

Lisa-Grafos
Co-Founder

Lisa was born and raised in Northern Canada, moved to Southern California as a teenager, and has never looked back. She absolutely loves the laid-back California lifestyle. After suffering with severe back problems for many years that included back surgery in her mid-20s, in 2008 Lisa discovered Lagree Fitness. After 6 weeks of regular attendance, her decade-old back problems disappeared! She was an immediate convert. She and her husband Dean decided to bring the incredible benefits of Lagree Fitness to San Diego. They opened their first studio in 2009, and thus CORE40 was born. In Lisa’s view, nothing is more true than the company’s slogan – Health is wealth.® When she is not working, Lisa enjoys traveling, hiking Torrey Pines, and spending time with her husband and 3-year old daughter, Viviana.

Tara is a bay area native but has roots all over the world (her parents live in Thailand!). She fell in love with Lagree fitness while she was living in Santa Barbara during college. When she discovered the Core40 studio in Soma, she was overjoyed to get back at it. Tara works in advertising, which brings crazy hours and stressful deadlines. She uses fitness as a stress release and it allows her to strengthen her body, since sitting at a desk for long hours leaves her body feeling drained. She is also a self-deemed health nut when it comes to nutrition. She felt a huge positive change when she switched to eating only whole/clean food and cutting out anything processed. Tara feels very lucky to be living in San Francisco, which gives her the opportunity to shop local and organic all year round. In her free time, Tara loves to run – she finished her first half marathon last year and has since been addicted! She also enjoys hiking, swimming, and traveling anywhere that involves scuba diving because she loves the ocean. She promises a challenging, upbeat, and diverse 40-minute class!

Her goal for all clients is to instill body awareness and a love/gratitude for one’s self. She constantly reminds clients that how you carry yourself on the machine, mentally/physically, is performed off of the machine, as well.
