Janessa Clark (Founder, Owner & Head Instructor) is a German-born New Yorker based between New York City and Stockholm. She holds an MA (Honors with Distinction) in Performance Practices and Research from London's Royal Central School of Speech and Drama in addition to a BFA (magna cum laude) in Choreography from Arizona State University's Herberger Institute for Design and the Arts. Janessa developed a passion for Pilates in 2001 in New York City while pursuing her career as a professional dancer and choreographer. She found that Pilates was the only system of movement that kept her painful lower back injuries under control. Janessa also began to notice a significant improvement in her overall strength, flexibility, and control while performing.

In 2005, Janessa became a certified Pilates Mat instructor through Steele Pilates/Teri Lee Steele (The Kane School Lineage) in New York City. Janessa was also a supervisor for the Steele Pilates Mat Certification Program from 2006-2011 and completed her Steele Pilates Cadillac/Reformer Certification in 2011 before moving to London. While living in London, Janessa went on to formally create the Pilates by Janessa brand so that she could interweave all aspects of her practice under one name and offer deeper training, through a variety of formats, to her global clientele. Janessa holds a comprehensive certification through BASI Pilates® and is a Pilates Method Alliance (PMA) member.

Always eager for knowledge, Janessa has completed courses for Pilates with Stability Balls, Foam Rollers and Small Props, Pre/Post-Natal Pilates, Back/Hip Pathologies, Pilates for Scoliosis, and Pilates for Special & Aging Populations. She also holds two Barre Fitness Certifications. Most recently Janessa has become a Core Consultant through the Bloom Method in Boulder, Colorado.

In 2014, the Pilates by Janessa brand become so popular that Janessa was able to finally realize her long-term goal of opening a Pilates studio in Stockholm. Since opening the studio Janessa has developed robust programming featuring open classes, private training, pre/postnatal courses, boot camps, retreats and detoxes. In 2015, the studio launched into teacher education by offering the first-ever BASI Pilates® Mat Teacher Training Program in Sweden. The studio is now the official Teacher Training Center in Sweden for BASI Pilates® International.  Janessa and the Pilates by Janessa brand continue to develop by welcoming in new instructors, maintaining a presence at international conferences, and branching out into international workshop education. Janessa is also a birth doula in training.

Carolyn Cesta (Pilates Instructor) is a Stockholm loving Canadian who took her first Pilates class 8 years ago and never looked back.  Practicing Pilates has made her feel stronger and more balanced in everyday life - while cycling around town, while doing her favourite outdoor activities including cross-country skiing, and even while sitting at a desk for 8 hours a day as a doctoral student at the Karolinska Institute.  As a newly certified BASI Pilates Instructor, she is eager to help others gain from the benefits of Pilates and excited to join the team at the Pilates by Janessa studio. 


Tim Kasper (Pilates Instructor) spent over 30 years globe trotting as a performer and student of movement an d theater. While traveling he simultaneously explored various therapeutic movement modalities that promised to help balance the body, refine and enhance expression, and improve access to the natural mechanism of the human body; basically searching  or“technique”. One day, after living and working in NY for 10 years, he realized that he had finally found a satisfying and reliable approach to singing, acting and dancing. He was suddenly working with one intention for all three disciplines and his teaching became infused with a clearer point of view than he had ever had.  The magic he was prescribed was Pilates.  The seed was planted and thus began his fascination with the Core Principles of Joseph Pilates’ universal, practical, and anatomically sound Method.

Maud Orain (Pilates Instructor) was trained at the International Physical Theater School Lassaâd at Bruxelles.  Working as a physical actress there, she was trained as a Mat Classical Pilates Instructor by Kelly McKinnon at CorpusStudio in Bruxelles and taught there from 2011 to 2013 before moving to Turkey and then Sweden.  She is now completing her apparatus training. She practices Tango and the 5 Rhythms dance,in Stockholm.
