Satoko Izumi-Espinosa, Instructor

Satoko is originally from Kyoto, Japan. She began practicing Pilates seven years ago to treat severe lower back pain and spinal problems that developed following the birth of her second child.

Satoko noticed the positive benefits that Pilates provided by transforming her body, mind and life and, in the process, gained strength, flexibility, freedom from pain and greater energy. From that point on, Pilates became her passion and she went on to complete the Body Arts and Science International (BASI) Teacher Training Program.

Since 2010, Satoko has enjoyed sharing her knowledge with others and strives to afford the same benefits to her clients by giving them hands-on approaches to Pilates. She develops training programs for new clients based on their unique needs. 

Satoko continues her study of Pilates, and the human body, through daily practice and research, and by attending seminars and workshops. She is bilingual and is fluent in English and Japanese.


Dorthy Waterman, Instructor

Dorothy Waterman has been a health and fitness professional since 1991.  A lifelong athlete and dancer, she finds herself most comfortable engaging in many forms of healthy activities including dance, weight lifting, biking, swimming, running and group exercise.

Dorothy has certifications in personal fitness training, Zumba, group exercise, senior fitness, Pilates, restorative yoga, and laughter yoga.  She trains individuals ranging in age from 40 to 95 in healthy body movement and leads group exercise classes from Zumba to Pilates to water aerobics.

 In her pursuit of personal growth and healing, Dorothy has discovered that the healing power of laughter can be nearly as effective a mood elevator as a 5k run. Plus it’s a lot easier on the joints. 


Abby Hanson, Instructor

Abby Hanson has been studying yoga and pilates for twenty years.  Her inspiration is to age gracefully and live free from pain.  Abby is classically trained in the Pilates method, but likes to combine modern Pilates movements in her teaching just to keep things interesting and fun.  

Abby recently began teaching yamuna body rolling.  YBR is ball rolling therapy that combines the release of massage with the strengthening and toning of exercise, providing an effortless workout and a deep stretch.  The balls apply traction that frees up connective tissue, reeducates muscle, stimulates bone, and leads to fully releasing negative holding patterns in the body. 

YBR is the perfect compliment to Pilates exercise.  If you are interested please look for future classes at Pilates of Pasadena or contact Abby for private YBR instruction today.

Toni Maddocks, Instructor

Toni's first interaction with Pilates occurred on the campus of UC Santa Cruz with a friend's suggestion that she take a mat class through the school's kinesiology program. With a background in dance, she found that the method's fluidity and focus on breath and muscle control was a wonderful complement to her fitness routine.

She studied for two years at the College of San Mateo under Balanced Body faculty member Sarah Artha-Negara’s instruction to receive her comprehensive Pilates training certification and has taught for the past two years at studios and gyms around the San Francisco peninsula. Originally from the Bay Area, Toni moved to the Los Angeles/Pasadena area to further pursue her passion in acting and filmmaking, while continuing to stay active through Pilates.

Her goal is to give each client a fun and challenging workout tailored specifically to their needs and fitness background. When not in the studio, you can find Toni in acting classes, camping with friends, singing karaoke, or reading recipe books (searching for that ever-elusive perfect chocolate chip cookie recipe).
