Jeni Jesse

Jeni Jesse, Certified Teacher

Jeni began studying the Pilates method in San Francisco as a client more than 10 years ago and quickly realized the benefits of this work, she became a bit of an addict. After two long and highly educational years of The Pilates Center of Boulder teacher training program she received her certification in May 2014. While working on this certification she also completed the Kathy Grant Heritage Training in Colorado. This training complemented the Pilates Center studies and has helped round out more of what this work can do for a body.

The Pilates method is useful in helping to transform the body, inside and out, aiding in strength, alignment, oxygenation, posture, and digestion just to name a few of the benefits.

Jackson

Jackson Grantham, Certified Teacher

I began training in Martial Arts in 2008, and completed my Brazilian Jiu Jitsu black belt certification through the world renowned Ralph Gracie by 2013. However, in 2010 my martial arts practice came to a halt after I suffered a neck injury that required surgery, which led me to the beginning of my Pilates journey. After three years of a dedicated Pilates practice, I was hooked, and decided to enroll in the Pilates Education Lab Teacher Training program. I've now been teaching Pilates since 2014 and the experience has been beyond rewarding. Fitness has always been a positive part of my life and I've enjoyed continuously learning more about the body through each movement system I've studied. The best part about teaching Pilates is that I love helping my clients learn how to embrace healthier changes in their bodies.

Lisa Prewitt

Lise Prewitt began taking movement lessons as soon as she could walk. She was introduced to movement imagery and anatomy as a child through Idiokinesis.. This was the beginning of a strong background in understanding the body and for creating a great body awareness. She majored in biology and chemistry while continuing to study and perform modern dance.She began integrating movement and the biological understanding of the body with the study of Ideokinesis, Laban/Bartenieff and Body-Mind Centering.

Jayne Reichert

Jayne Reichert, Trainee

Jayne has spent the last 25 years either behind the stove in a professional kitchen, at the farmer’s market shopping, catering someone’s life celebration or standing in front of a roomful of people, teaching them how to cook. It’s been an amazing journey! Last year as a birthday present to herself, she took the year off and headed south of the boarder to surf, cook, eat and hit the “reset” button. That time was very reflective and filled with thoughts about what to do next. Whatever it was, she needed to be as passionate about it as she was about cooking and teaching. Working out and being physically fit has always been very important to her and the idea of being a personal trainer crossed her mind once or twice, but there was something missing in that. It didn’t feel as engaging to her.

Her first Pilates class was at least 22 years ago at the Club One in the Fillmore. She still remembers how absolutely electrifying it was, literally from the top of her head all the way down through the tips of her toes. It was intoxicating, but at the time not very realistic for a culinary student. Fast forward 20 years, a career spent on her feet and a minor surfing accident (the board went one way and her knee went another) and well guess where she ended up, yep in Pilates. She originally turned to Pilates as a way to rehabilitate her knee without surgery or loss of time at work and it was very effective. So, as she sat on that beach in Mexico and toyed with ideas about what to do next, the idea of Pilates and training to become an instructor kept returning to her. The idea of not just movement but the whole mind body breath connection and the concept of returning to movement or rather finding freedom in movement by connecting all the parts. It is definitely a humbling experience, as your weaknesses are identified very quickly and there’s nowhere to hide. It’s challenging. That challenge energizes and inspires her and that is what she’d like to share and pass on to others as she continues on this journey to fine tune her own practice.


Fernanda Repsold

Fernanda Repsold, Senior Teacher

Fernanda Repsold was first introduced to Pilates in 2002 as a suggested form of rehabilitation for a foot injury she incurred while training for triathlons.  In the process, she found that Pilates not only helped towards her successful recovery, but also helped unleash her passion for simple and complex patterns of movement throughout the whole body. As an athlete at heart, and an avid practitioner of yoga and gyrotonics, Fernanda believes Pilates is the binding ingredient that keeps the body strong, balanced, and free of injury.  Fernanda enjoys working with people from all walks of life, and is especially interested in applying Pilates as a means of stimulating the body's natural ability to heal.  Her style of teaching fosters a collaborative process of discovery, combining form and function, while always looking to the whole body to create a supple and uniformly developed structure.

Sidney Tarlow

Sidney Tarlow, Apprentice

My addiction to Pilates began when my body decided to stage a coup d'etat. I have always been a very active body, but once I hit fifty, no matter what the attempt at a workout, I inevitably sustained an injury. I become obsessed with problem solving this immense obstacle. I decided maybe a DVD or two trying different disciplines might end my misery. Much to my delight, I came across a Pilates DVD which changed my life, quite literally. I finally found a safe and joyful way to move again, in a way that I had never felt before. This was nirvana as far as I was concerned. I was so thrilled with this new found freedom that I decided to find a studio where I would endeavor to actually take a class. After extensive research, I came across "Internal Fire Pilates". I began taking community mat classes with one of the multi talented members of the staff, and that was it; I was officially addicted! Soon thereafter I realized this was my path. My aim is to connect with folks who feel stuck. I want to teach them how to move through things metaphorically and literally.

I am now an apprentice at this amazing studio, and have completely fallen head over heals for the staff, my beautiful clients and my own body. It's like those dreams when you're flying. By the way, I'm having allot more of those these days!
