Shelley Ballestrazze – Owner/Pilates Instructor

Growing up in Boulder, CO, Shelley was very active in sports but struggled constantly with injuries and chronic lower back pain.  As the most injured player on her high school basketball team, she now knows the importance of regular stretching and a flexibility program.  She tried Pilates in early 2001 as a means to cure her repeated running injuries and to alleviate muscle tightness.  After steady practice, she discovered she was able to live pain-free and became an advocate for the Pilates Method.  She worked in the corporate world for 20 years and prior to becoming a Pilates instructor, she finished up her corporate career as a computer technician and software trainer.

Going through a very rigorous and comprehensive 650-hour initial training program, she earned her Pilates certification in 2003 through Body Kinetics, under the tutelage of Master Instructor, Carol Appel . After completing her training and internship at Body Kinetics in Mill Valley, CA, she opened her first studio in 2005, Pilates of Marin. Her clientele quickly grew and in 2008, she expanded, doubling the size of her previous studio.  In 2009, she relocated to Oregon and in 2010, decided to sell Pilates of Marin to a trusted friend and colleague.  She opened NW Core Balance in Tualatin (Portland), Oregon in 2011.

As a breast cancer survivor, Shelley has worked extensively with individuals post-cancer treatment.  Undergoing two surgeries and radiation therapy treatment has truly helped Shelley to understand the physical needs of all cancer survivors.

When not teaching Pilates, Shelley enjoys mountain biking, running, snowshoeing, and spending time with her husband and two dogs.

Amy Holstein – Pilates Instructor

Amy has always had a passion for health and fitness. As a serious yoga practitioner, Amy tried Pilates in 2006 as an adjunct to her yoga practice. Pilates appealed to her sense of structure and she loved the deep strengthening and physical transformation she felt in her own body. Since completing her Instructor certification in 2010, she has enjoyed teaching creative, challenging and effective workouts, designed to meet the needs of students of all levels and abilities. She believes Pilates is an amazing way to strengthen and align the body, avoid injury and build a stable foundation for other forms of exercise and activities. When not in the studio, she enjoys hiking with her dogs, horseback riding, yoga and exploring life with her two kids and husband.

Kacie – Pilates Instructor

Kacie is passionate about understanding how the human body functions best. She began her Pilates practice to manage her own scoliosis and instantly loved how her practice developed her confidence, sense of self and stability. These changes influenced her to reassess her life and leave her corporate career to focus on becoming a Pilates instructor and helping others on their paths to wellness. Kacie was STOTT Pilates certified in October 2013 and has never regretted her decision to make Pilates her life’s work.

When she’s not on the mat Kacie enjoys exploring the Pacific Northwest with her dog Theo, playing disc golf, reading and studying biomechanics. Her greatest joy is watching her clients transform from a place of pain, discomfort and sedentary life to a place of mobility, stability and wellness. You’ll love her radiant positive energy and engaging smile.

Britt Newcomer – Pilates Instructor

Britt has been a student of Pilates since age 7.  As a ballet dancer, she used Pilates to condition her body and improve her movement patterns.  While she no longer dances, she continues to be passionate about Pilates as an exercise form for all body types and fitness levels.  After spending 12 years owning a manufacturing business, she has decided to pursue teaching Pilates as a career.  She loves creating workouts that are safe, fun, and beneficial, and hopes that clients come away from her classes feeling as excited about Pilates as she does.

When not in the studio, Britt can be found with her husband and two kids – camping, sewing, cooking, and solving the occasional calculus problem.
