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.

She graduated from USD with a Bachelors of Psychology and is currently getting her Masters of Nursing from USF. She loves to be active and always on the go.

CORE40 Supertrainer Leticia

Leticia is a San Francisco native with a background of ballet. She’s always had a passion for health and fitness and is currently studying nutrition. She fell in love with the Lagree method back in 2014 when she took her first full body class and never felt her muscles working so hard. The feeling of that instant effectiveness in her muscles followed by satisfying results got her hooked! With 2 years of commitment to Lagree, she’s never felt stronger, and she’s ready to give that experience to her clients.

Kimberlee is a lifetime martial artist, holding a first-degree black belt. During her college years she tried to enter the Hollywood stunt scene but unfortunately was held back when she tore her ACL and meniscus. After the surgery, her knee was never the same and she learned to live with the pain while remaining active.
When she discovered CORE40, she was blown away by the intensity of the workout while being left PAIN FREE in her knee (not to mention her abs reached a new level of definition). She truly believes it is a life changing workout and is eager to instruct CORE40 students and help them overcome injuries and reach their goals.
Outside of of the studio, Kimberlee and her (Italian) husband own an Italian handbag company, love traveling, scuba diving, cycling and cooking.

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.

Charlene is a southern California native that moved to San Francisco a few years ago. As a child, Charlene was immersed in athletics so it was only natural that she gravitated towards fitness as an adult. As an avid runner, Charlene didn’t understand the impacts of group fitness until she discovered the Lagree method. The slow controlled movements and isometric holds targeted muscles in the body she didn’t even know existed and within minutes of her first class her muscles where shaking. She instantly became addicted and loves how the workout is continuously challenging. Her love for group fitness and Lagree motivated her to become a certified indoor cycling and Lagree fitness instructor.

Dani was born and raised in Miami, FL and moved to San Francisco two years ago. She discovered Lagree four years ago while attending college at Brandeis University in Boston and immediately fell in love with the workout.
As a soccer player and athlete her whole life, Dani saw Lagree as the perfect balance of a toning and strengthening workout she was always looking for. Every time she travels to a new city she takes classes at Lagree studios, so it was no surprise that as soon as she moved to SF she found her home at CORE40 and pursued her passion of becoming an instructor.
You might see her taking different fitness classes around the city and her regular workouts consist of spinning, Lagree, and running!

Favorite move- Mega chest press

Ekaterina (Katya) grew up and went to college in San Luis Obispo, California. Right after graduating from Cal Poly, she moved to San Francisco for law school and stuck around after passing the bar. Katya discovered Lagree through Classpass, and it was love-hate at first sight! The excitement of getting the form right, along with the an amazing full-body workout, kept her coming back time-after-time.
After about a year and a half of being a CORE40 client, Katya transitioned into SuperTrainer-trainee. She eventually bit the bullet and began teaching. Not only was it a perfect way of stepping outside her comfort zone, but also an amazing way to help clients transform themselves. There is nothing quite like seeing clients’ excitement at perfecting a move and getting that muscle shake!
Steve has been very active in sports all all his life. He went to college on a Diving scholarship to University of Maryland, and qualified for NCAA’s. When he finished his career as a diver, after graduating college, he needed something to help him stay in shape. He tried lifting, running, yoga, crossfit, etc. and either he didn’t like the workout, or he was not getting the results he wanted.
His partner, also a Lagree instructor, took him to his first class and he was hooked immediately! They even completed 100 classes in 100 days.
His favorite parts of teaching at CORE40 are the high intensity workouts, upbeat music, and creating big energy. He makes each class challenging, fun, and with a focus on form and pace. He loves watching people push themselves to the “shakey shakey.”
Some of his favorite moves are Plank to Pike, Spider Kick, French Twist, and Escalator Lunge.
When he’s not teaching, take a look around because he’s probably in class next to you!

Come sweat with Emilie.
Even a few years after college, Emilie could probably count on two hands the number of times she had worked out in her life. Once she took her first class on the Megaformer, Emilie’s commitment to fitness changed quickly… She became instantly addicted to the intensity of the moves, and she took Lagree classes almost every day before becoming an instructor!
Emilie brings the love, challenge, music and positivity and the challenge to each and every class!

Carla discovered and immediately fell in love with Lagree over 3 years ago. After spending a few years as a student and seeing the changes that happened both physically and mentally, she decided to take her experience and help others find the gratification and results CORE40 offers.
