The Team


Dean is a Southern California boy, born and raised in North Hollywood, CA. Dean has always been a fitness enthusiast, from weight training and boxing to yoga and cycling – he has pretty much tried it all. 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.

Co-Founder & CEO

Lisa was born and raised in Northern Canada, moved to California as a teenager, and has never looked back. In 2008, after suffering with severe back issues for many years that included disk surgery, Lisa and her husband Dean discovered a revolutionary new exercise method called Lagree Fitness. After 6 weeks of regular attendance as clients, Lisa’s decade-long struggle with back problems disappeared! She was an immediate convert. She and her husband Dean decided to bring the incredible health benefits of Lagree Fitness first to San Diego, and then to San Francisco, 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, nature, writing, and precious family time with her husband and young daughter, Viviana.

Favorite CORE40 Exercises: French Twist (for the challenge) and Escalator Lunge (for balance and the glutes)

Core40 Instructor

Stephanie moved to San Francisco 4 years ago from Hawaii. Trained in various dance methods, Stephanie brings her love of music and movement to the bike. Stephanie fell in love with spin after her first few classes and knew right away she wanted to make the leap from rider to instructor. For Stephanie, being active on an off the bike is about being confident and being able to take that with you when you leave the studio

Core40 Instructor

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!


Rose is originally from Nebraska (go, Huskers!), but has been an SF native for 8 years now and loves it. By day she is a tech nerd, and by night (and weekends) she loves to be active. She has tried almost every form of workout, from yoga, barre, swimming, running, etc. She discovered Lagree Fitness 4 years ago, and became addicted, as it helped tremendously with her core strength and running. She can’t wait to see you all in her class!

Favorite CORE40 exercise: Flying Spider Kicks (because you use your whole body, and when you do it right, it seems to defy gravity and shows off how strong CORE40 makes you)

Core40 Instructor

Melody has worked in the medical field for the past ten years. A true believer that health is your wealth, she made it a priority to exercise regularly. Melody fell in love with Lagree Fitness the day she experienced her first class. Instantly addicted, she knew she wanted more. She drove an hour away weekly to a studio that taught the method. After two years of practicing, she not only watch her body change, but Lagree Fitness also strengthened her neck and back. No longer needing weekly chiropractic treatments for her lower backaches, she became a true believer of the method. Melody was overly elated when she discovered that CORE40 had arrived in San Francisco. She really enjoys spending her free time teaching the method she loves best! She is also an avid lover of hiking, snowboarding, indoor rock climbing, group fitness classes, and roller blading. Yes, she still roller blades!

Favorite CORE40 exercise: Mega Plank-to-Pike (so intense!)

Core40 Instructor

Caitlin is originally from Los Angeles and has lived in San Francisco for nearly two years. She loves walking adventures, hanging out with her family and traveling. Caitlin fell in love with Lagree fitness after the birth of her first son. It is the best workout she’s ever tried since her days as a ballet dancer.

Her favorite things about teaching are seeing people get strong quickly, loud music, and correcting form!

Caitlin’s fave moves are bear and reverse catfish

Core40 Instructor

Stephanie was born and raised in Miami, Florida. She moved to the Bay Area in 2009 where she received her Master’s in Counseling. Growing up, she was involved in all different types of sports including but not limited to Gymnastics, Soccer, Track, and Cross-Country. She found her true love of fitness when she took her first indoor cycling class in 2007.

Stephanie is so excited to be part of the CORE40 team. You can expect lots of sprints, sweating, and smiling when taking her cycling class. When she is not in the studio teaching, you can find her whipping up new recipes in the kitchen, doing anything outdoors, and watching good movies with her husband!

CORE40 Instructor Jessie Li

Jessie grew up in the Bay Area, went to school in Chicago and worked in LA before returning back to SF. She was honestly never into health or fitness until ClassPass, where she discovered CORE40 and the Lagree method. She quickly became addicted to the workout after noticing how effective it was and how the workouts continued to be challenging many, many months later. Outside of teaching Lagree and her full-time job at the typical SF tech company, she also practices yoga and does aerial silks, and loves exploring new restaurants, traveling and outdoor adventures.

CORE40 Instructor June Luo

After growing up all her life in Milwaukee, Wisconsin, June went out to the East coast for college (Go Penn!) but ultimately decided that California was the place to be. She moved to San Francisco in 2014 and has been loving it ever since. She’s really glad she chose Nob Hill as her home since that is what helped her discover Core40 from the very beginning as an avid lover of the Lagree method, intern, and now instructor! While not working in Inventory Planning at Gap during the day, June loves taking both the spin and reformer classes at Core40, runs through the city, wine tastings, hiking, and trying new brunch spots (but really basically anything to do with food)! She is super excited to start teaching classes at Core40 and help spread the burn!

CORE40 Instructor Lisa Tompkins

Lisa is a native New Yorker who made her way to the Bay Area in 2012. She attended the University of Nevada, Las Vegas, where she studied hospitality management. From Vegas she moved to Orange County and then over to Santa Fe, NM before she ended up in The Bay. She is a true freedom and fitness junkie. After leaving her desk job back in 2014, Lisa found her passion to teach. She became a cycling instructor right away and knew she wanted more. After taking classes at CORE40 for almost 2 years she knew it was time to start teaching the method she became so passionate about. When she is not in the studio you can find Lisa working out by Lake Merritt, working on her wellness blog, or planning her next adventure.

CORE40 Instructor Tiffany Vo

Tiffany found herself in the fitness industry after she failed to convince her anatomy teacher that medical school was her next step. Her professor made her take a career test where Tiffany came up with fitness instructing as one of the occupations, and the rest is history.

When the chance to teach at CORE40 came along, Tiffany quickly jumped onto the opportunity. “I knew I wanted to teach here after the first exercise, wheelbarrow. My muscles were shaking all over and I loved it!”

Tiffany loves combining her science education, dance/yoga background, and positive character to give her clients the best class possible. 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.

Feel free to join Tiffany in a dance, yoga, barre, bootcamp, or even CORE40 class. She loves taking class with clients. Exploring and eating all of the wonderful food that San Francisco has to offer, or listening to live music at a local venue are also valid options.
