Hi! My name is Cassie Phillips. I am a wife, mom, and fitness lover! I am a certified personal trainer and have a degree in Respiratory Therapy. I value clean eating, exercise and moving, people and relationships, and balance to enjoy all of these awesome gifts. When it comes to your workouts, I believe you should find something you enjoy, include some energetic and positive people, and do it often! I love leading fitness in a group setting and promise to deliver the very best in class programming, energy, music, and results.


Leanne is a Bay Area native who values a holistic approach to wellness, and strongly believes in the importance of integrating mind-body practices and exercise. She has been a member of Shape Up! since 2013 which fostered her passion for fitness and motivated her to e  arn ACE-certification in personal training. Leanne's other passion is in providing mental health services to marginalized populations. She graduated from Cal Poly, SLO in 2005 and earned her PhD in clinical psychology from Palo Alto University in 2012, with emphases in neuropsychology and forensic psychology.

Sabrina Elizabeth Brown is a Pediatric Nurse by night and fitness instructor by day! She started her fitness journey three years ago right here in Pleasanton. She joined a gym when she was a very unhappy, unconfident graduate student who weighed in at 247 pounds. Dance fitness including Zumba and U-Jam helped her to live a healthier lifestyle and she found herself 119.2 pounds lighter. Sabrina wants to continue to inspire men, women and children to never give up, follow their passions and to be happy, healthy people. Apart from dance fitness, Sabrina loves to run (ten marathons complete, including Boston and counting!), lift heavy things, eat chocolate (what girl doesn't?) and try new adventurous things (did somebody say ziplining through the Amazon?) Dance brings out a joy in you that she does not believe any other fitness activity brings! So come take some time and rock out with her on the dance floor and leave with lots of sweat and lots of smiles!
