Growing up in Australia Natalie was part mermaid living in the water. After coming to America though there was no exercise that particularly appealed to her to do.

In 2001 Natalie’s roommate had found Pilates and insisted that she try it out and thus Natalie attended her first Mat class with Mark. Unconvinced that she would ever achieve any of the exercises it was not until Natalie’s Boyfriend now Husband deployed to Iraq the first time that she immersed herself in Pilates when not at work in the hospitality Industry.

In 2008 Natalie attended Marks Mat and Machine classes determined to help others find the enjoyment she had through Pilates. In the middle of training Natalie had her first child and found that Pilates helped with many of the aches and pains of pregnancy and delivery. Unfortunately she had not understood at the time the demands of a new family and work and thus need to take a break from her training.
After the birth of her second child Natalie left the demands of the hospitality industry to finish her training and found the enjoyment that first drew her to the exercise along with many benefits of Pilates after children.

Erin became a certified level Pilates Instructor in July 2007 through Jen Campbell’s Articulate Eye Pilates teacher training program at the American Dance Institute. Erin is also a certified level practitioner of GYROTONIC® and GYROKINESIS® and has studied to teach with the method’s creator, Juliu Horvath and Master Trainers, Hsiao-Fang Lee and Tracy Monaco. Erin first discovered Pilates in a dance class at Penn State University while pursuing her degree in Arts Administration. She then encountered Pilates again while working at the American Dance Institute in Rockville, MD and began her intense practice of the Pilates method. Erin’s love for the Pilates method grew from the unique body awareness and deep strength it cultivated within her. Every  movement, even simply walking up stairs, became a new and more powerful experience. Her discovery of the liberating movements of GYROTONIC® and GYROKINESIS® reminds her of what it felt like to swim or dance as a child. Erin’s goal for each lesson is to empower her clients with insight that improves how they move and feel outside the studio. She approaches time with her clients with an appreciation for how Pilates and the GYROTONIC EXPANSION SYSTEM® can be modified to provide beneficial results for any age or ability, from young ballerinas and athletes to inspiring people in their 90’s. Her clients often comment on her attention to detail and her gentle but challenging teaching style.

Sustaining an athletic injury that required surgery as a teenager taught me a lot about the importance of a quality rehabilitation program. I was motivated to learn all that I could to contribute to my own recovery. In the process I was fortunate to discover a career that I am passionate about. My goal has always been to help people to help themselves. After 34 years, I am still excited to learn all that I can from and about each patient in order to tailor individualized treatment programs. I believe in creating strong relationships with the traditional medical community, holistic medicine practitioners, and wellness professionals for a truly integrative approach to rehabilitation. Understanding the importance of self-care in the healing process, I endeavor to help my patients develop more awareness of the mind-body connection to recover from injury and optimize their health.

After graduating from the Philadelphia College of Pharmacy and Science with a B.S. in Health Science and Master of Physical Therapy degree, I served as an officer in the United States Army working in the U.S. and Germany. Throughout my years of practice and ongoing continuing education in physical therapy, athletic training, and Pilates, I developed a strong manual therapy approach and a variety of techniques to care for my patients. I have worked with a diverse patient population including those with orthopedic, neurological, and oncological conditions. Having a special interest in treatment of the spine, post operative breast cancer rehabilitation, and pre and postnatal orthopedic conditions, I’ve found incorporating Pilates based rehabilitation to be an effective tool in recovery.  As a competitive rower, I enjoy working with rowers of all ages and abilities, but I particularly enjoy working with Masters rowers.

After completing a fellowship in Sports Medicine, I became a NATA certified athletic trainer. I am a Certified Pilates Teacher through the Pilates Method Alliance and served as an adjunct faculty member at George Washington University in the School of Exercise Science.
