Danielle mitchell

Owner & Instructor

Danielle holds undergraduate and graduate degrees from Rutgers University School of Criminal Justice. After working a corporate desk job for many years she began to feel the wear and tear in her body. This led her to Pilates in 2011 where she fell madly in love with the discipline and soon thereafter completed her classical Pilates certification in Santa Monica, CA. She is a third generation instructor who has experience with all ages, injuries and athletic abilities.


Danielle also holds a Pre & Post Natal Pilates Specialist Certification through Fusion Pilates. Having this additional certification is essential when instructing prenatal, postnatal and menopausal women. Not many instructors in LA hold this very vital certification, or have her personal experience in this field.    

Whether she is teaching a private or duet session, she is known for balancing her cheerful, energetic encouragement with butt-kicking workouts, all the while keeping it fun. On a daily basis Danielle is inspired by the changes she sees in front of her as she watches people build strength and make health a priority. Danielle will always guarantee "a sweat and a laugh"!

When she is not in the studio Danielle enjoys spending time with her husband and toddler son doing all things LA.

Devon Simon

Afternoon & Evening Instructor

Born and raised in the Bay Area, Devon began doing classical Pilates with her mom as a teen. She would later move to Los Angeles to pursue a career in costumes for TV & Film. After years of being a set costumer for extended hours, Devon revisited Pilates as a way to relieve her body and mind of the stress and exhaustion from her job. She fell in love with Pilates all over again and went on to become classically certified through the Pilates Institute of Southern California, completing over 800 hours of training and practice. She hopes to help others experiencing stress or exhaustion to reconnect with their body and mind. When she is not teaching Pilates, she loves to spend time with her family and two dogs.

Allie Derosa

Evening & Weekend Instructor

Born and raised in New Jersey, Allie began her Pilates journey as a client at CoreSpark after moving to Los Angeles four years ago. Under Danielle's guidance, she reconnected with her body and fell in love with how strong and capable the practice of Pilates made her feel, both physically and mentally. With a desire to combine her 12 years of experience in public education as a teacher, assistant principal, and leadership coach with her passion for Pilates, she went on to pursue a comprehensive Pilates certification from Love For Pilates in Santa Monica. She is thrilled to be back at CoreSpark as an instructor to help others find strength, connection, and joy while moving their bodies.
