Nadia Rodriguez

Owner, Bodytonic Pilates
Certified Pilates Instructor

Nadia’s first experience with Pilates began in 1990, using mat exercises to cross condition for her dance training, and in 1995 using pilates equipment to rehabilitate dance related injuries. For her instructor training she studied under Jane Erskine, owner of one of the first Pilates studios in Seattle and daughter of famed ballerina and first director of the Pacific Northwest Ballet, Janet Reed. Nadia completed her instructor training in 2002 at the Pacific Northwest School of Pilates and is a registered instructor with the Pilates Method Alliance, an independent organization dedicated to protecting the public by establishing certification standards for Pilates professionals. She has developed a loyal following from her work teaching in Pilates & yoga studios, physical therapy clinics, & in personal home gyms. Nadia’s practice involves working with professional athletes to those recovering from injuries and the application of both classical and contemporary Pilates techniques.  Her philosophy prioritizes her client’s goals and desires while teaching them how to produce somatic longevity, efficiency, and balance.

In addition to Pilates, Nadia has over 30 years of professional experience in the movement field including gyrotonics, yoga, gymnastics, and both classical & modern dance. Prior to becoming a Pilates instructor she trained and danced professionally in both Seattle and NYC where she was a trainee with the Martha Graham Dance Company. Nadia holds a B.S in Physical Activity & Health from Eastern Oregon University and a certificate in Women’s Exercise Training and Wellness from Washington State University.

Lenzie Gulin

Certified Pilates Instructor

I was born and raised in Curitiba, Brazil. From a young age I was a dance and fitness enthusiast, and upon moving to the USA in 2000 I quickly discovered Pilates and became an avid practitioner.

My college degree is in Architecture and Design. That training helped me to develop and launch a line of women’s fitness apparel in 2003 called FITLEE. The line was focused on the Pilates and Yoga communities and in promoting the brand I was able to meet and work with instructors from diverse lineages and approaches to the Pilates Method.

In 2005 I met Rebecca Leone and she started me along the path to a deeper understanding of Pilates and movement biomechanics. I have since taken a number of her workshops and cadaver lab classes and consider Rebecca to be my key reference and Pilates mentor.

In 2013, having practiced and worked around Pilates for more than a decade, I decided to pursue it as a career. Going through Rebecca Leone’s Comprehensive Teacher Training Program has directed my approach to the work with a strong focus on spine safety.

I love helping people understand the mechanics of proper alignment and muscular engagement and how it all relates to our everyday activities and general physical and mental health.


Sarah Poulsen

Certified Pilates Instructor

Sarah has a passion for health, wellness and happiness and loves to share her passions with others. Along with a bachelors degree in health and behavioral sciences from the University of Utah, Sarah is a Stott certified Pilates instructor and has experience teaching aerobics, barre, dance and HIIT classes. Her dance background is what originally drew Sarah to Pilates (and NYC), helping keep her muscles and joints healthy for the physical stresses of dancing. But she truly believes pilates is good for anyone and everyone! Her class really focuses on the importance of alignment and working your muscles correctly, through breathing, control, contracting, elongating and stretching. You will feel well balanced and refreshed after her mat pilates.

Healed from her injury and having a deeper understanding of proper biomechanics, Erin continued to use Pilates as cross training in dance. Erin received her Pilates certification in New York City at the Kane School for Core Integration and was a trainer in both New York City and San Francisco. Erin’s experience as a dance educator includes being a dance specialist at the Bronx Charter School for the Arts, Director of Education Outreach for RIOULT, a professional modern dance company, and a teaching artist for numerous dance companies. Erin was a project consultant for Johnson & Johnson’s Gateway to Healthy Communities Project in Philadelphia and New York City and a teaching artist and Family Services Manager at Luna Dance Institute in Berkeley, CA. Through all of her work with children, families and adults, encouraging and promoting health, happiness and wellness is at the core of her efforts.
