About Us

After earning her Master of Arts degree in Exercise and Sport Science from the University of Sydney, Nellie has spent more than 20 years developing and teaching Pilates programs for clients with specific medical needs, including chronic back pain, spinal stenosis, hip and knee replacements, and more.

Her experience includes six years as the Pilates Department Manager for Fitness and Wellness Services in New Jersey, as well as owning and operating her own Pilates studio in Sydney, Australia. Six years ago, Nellie opened MIXX Fitness in California, where she continues to bring her experience, care, and personalized approach to helping clients move better, feel stronger, and achieve their goals.

Jen stepped away from her career as a Speech Language Pathologist working in special education in order to raise her three children. Now that her youngest is in his last year of high school, she is ready to start something new. She has always valued an exercise routine, but it wasn't until she discovered Pilates three years ago at MIXX studio that she truly enjoyed it. After watching her mom suffer at the end of life with several medical issues and physical limitations, she is committed to keeping active. Pilates is the perfect exercise to help with core strength, balance and flexibility which are all key for healthy aging. She looks forward to sharing her enthusiasm with students of all ages and abilities.

Sue came to Pilates later in life and was drawn to how it made movement feel more intuitive and accessible. Having navigated her own shoulder and neck injuries, she helps clients build strength, improve mobility, and better understand their bodies. She believes exercise should be effective, sustainable, and fun, and strives to make movement approachable for every body. Sue trained with Nellie Brook, completed comprehensive Pilates teacher training at the College of San Mateo, and is a certified 500 hour yoga teacher.

Shiri's Pilates journey began seven years ago while recovering from an injury. She was instantly captivated by the magic of the practice. Its precision, intentionality, and the seamless way it strengthens both the body and the soul.

As a dedicated member of the MIXX community for more than five years, Shiri underwent a complete lifestyle transformation. Her fascination with anatomy and movement inspired her to transition from a student to an instructor, where she now applies her professional background as a multidisciplinary designer to crafting creative and thoughtful class sequences. Shiri views movement through a lens of aesthetics and flow, with a special affinity for the Chair and exercises that challenge strength and balance.

Outside the studio, she continues to integrate beauty and creativity into all aspects of life and enjoys long daily walks with her dog, Molly. She looks forward to sharing her passion and enthusiasm with the MIXX community.

Jean discovered Pilates over a decade ago while recovering from a back injury and it completely transformed her relationship with her body. By building strength from the inside out, especially through deep core work, she was able to heal and return to an active life. That experience sparked a passion for Pilates as a powerful system for recovery and resilience. She is dedicated to helping others feel strong, supported, and confident in their bodies, no matter where they're starting from.
