Roshan Amendra

Roshan Amendra, also known as “Rosh”, is the owner and director of A.B.S. Training Centre. Since the age of six, Rosh trained to the highest level possible in gymnastics, competing with Team Canada for over 10 years.  He has also performed on many stages internationally as an acrobat, break dancer, tumbler, choreographer, director, stilt walker, aerialist, and stuntman. Some have said that seeing Rosh in action is like simultaneously riding a rollercoaster and watching fireworks with his precise movement and versatile skill set on the ground and in the air!  However, as impressive as that is, the tricks and list of credentials are not what feeds his passion. What matters most to Rosh, is the foundational training that supports the strength, biomechanics and fluidity of movement — not only for gymnastics — but for any sport or movement discipline.

With the combined knowledge of Rosh’s former coaches and fellow athletes, Rosh has developed and system that not only gains results for skills but also acts as a training system to prevent and rehabilitate all types of injuries.  An overlooked and key component for the longevity of movement.  Certified as a coach, Rosh has a zen-like teaching style and philosophy.  A keen observer of the nuances of body mechanics, Rosh focuses his attention on the unique and distinctive movement patterns of each student. Some of those patterns are helpful, but often the student will demonstrate habits that actually hinder progress. Furthermore, Rosh probes how the student thinks, which reveals underlying issues. In a sense, the mind/body can conspire to keep the student from improving. But when you know, trust and apply the technique — everything works!

Rosh says he does not train and condition muscles. He trains and conditions the nervous system. By making incremental changes in the way the muscles fire, gradually the brain rewires to develop more beautiful, healthy and efficient patterns.  Virtually all of his students — and parents — testify to fascinating changes in their body mechanics. Flexibility has increased. Strength is reliable. And, most importantly, their approach and execution are transformed.
Rosh says, “I don’t care how tall or short you are. I don’t care if you have physical issues or even if you have lost a limb. I don’t care if you have Autism or ADD or ADHD. What I do care about is that you bring your passion, your deep desire to learn, your discipline, your dedication — because I can work with those and I can guarantee that together we will change your world.”

Deryn Sherk

Deryn’s interest in human movement developed from her involvement in competitive cheerleading and training in gymnastics and circus. This led her to pursue an Honours Bachelor of Applied Science in Kinesiology from the University of Guelph and a Diploma in Fitness and Health Promotion from Humber College. While completing her education, she gained extensive knowledge in human anatomy, physiology, biomechanics, biophysics and exercise technique and prescription. With a desire to further her knowledge of sports injuries and athlete development, she is currently completing a Master of Science in Sports Science and Rehabilitation from Logan University. Deryn’s education has provided her with the ability to understand the psychology of athletes during training, how their bodies react and adapt to various training stimuli and how to properly develop athletes over a long-term period.

In addition to school, Deryn has trained under Rosh for many years, advancing her understanding of tumbling, handstands and aerial circus. She has also obtained gymnastics coaching certifications from the National Coaching Certification Program, as well as received training on athlete development from high-performance training facilities such as EXOS and the U.S. Olympic Training Center.

Deryn combines the science-based knowledge from her schooling with practical experiences learned through her own training to provide high quality coaching to every athlete that works with her. Knowing very well the importance of a strong foundation and correct psychological approach to training, she is guaranteed to help all athletes develop the strength, mobility, movement patterns and mindset to reach their peak athletic potential.


Katelyn Ettinger

Katelyn Ettinger was born and raised in the beautiful Annapolis Valley of Nova Scotia, Canada. Her story begins as a young 6 year old competitive gymnast training and competing in Artistic Gymnastics, as well as Trampoline and Power Tumbling. At age 14, Katelyn began training in dance to support her gymnastics training. Soon after, she began competitive dance training in a variety of disciplines and even began teaching at her local dance studio, while also coaching gymnastics at her home gym. After graduating from High School, Katelyn went on to earn her Bachelors Degree at Saint Mary’s University from 2009-2013. During that time she attended dance conventions in Halifax, Toronto and New York City while continuing to teach competitive dance and choreographing for the Varsity Dance Team. Katelyn’s choreography has been showcased at a variety of competitions and events throughout Canada and the United States, including The Dance Worlds at Disney in Orlando, Florida.

Recently, Katelyn has choreographed for the Juno nominated kids pop band Marlowe & The MiX featuring Raina Harten, Ethan Young (CTV’s The Launch) and Johnny Orlando, as their concert choreographer. Their song, WE Change the World, was recently performed at WE Day Toronto 2017 and WE Day Ottawa 2018. Katelyn has also choreographed for Toronto Dance Project, the National Music Camp of Canada, and programs for empowering young girls and at-risk youth. Katelyn teaches full time from September to June for Canadian Dance Company and Randolph Academy of Performing Arts, specializing in Acrobatics and Tumbling. When she is not in the studio, Katelyn can be found teaching at Dance Attack Acro conventions (British Columbia, Halifax and Ontario), Student Expo, Toronto Dance Teacher Expo and for the Performing Arts Educators of Canada. In the summer months, she teaches Acro workshops in multiple studios throughout Ontario, and travels coast to coast teaching intensives throughout Canada. She has her National Coaching Certification for Gymnastics (NCCP), her Acro Dance certification in Acrobatic Arts (AAC) and her professional flexibility certification with Alixa Flexibility (AF). Katelyn is often recognized for teaching dancers advanced tumbling skills/skill variations as well as drills for setting a solid foundation in young acrobats.

Meaghan McGill

My passion for coaching and training stems from a personal background in sports as a previous gymnast and current dancer. Through many hours of training as a gymnast, I was able to build a strong foundation in strength, flexibility and technique which followed me into my dance career. As a previous studio dancer, I trained and competed in almost every style, but decided to pursue my passion for hip hop. Since then I have had the opportunity to compete internationally at world hip hop championships in countries such as Denmark, Italy and Scotland.  In 2017, I received a diploma with honors from Humber College in Fitness and Health Promotion. This led me to continue my studies at the University of Guelph-Humber where I have recently graduated with honors, receiving a BASc in Kinesiology. Throughout my studies, I have taken courses that furthered my understanding of the human body in areas such as exercise physiology, functional anatomy, biomechanics, injury management/prevention, fitness assessment, and athletic coaching. I have also taken courses focusing on sports psychology, motor learning/neural control and behavior change. This education has allowed me to apply a more scientific approach to my coaching.  My previous experience coaching gymnastics and teaching dance allowed me to share my own training experiences and knowledge with other athletes. I was able to better understand the movement mechanics required and noticed common strengths and weaknesses within each movement. Since completing my placement at ABS and continuing to coach afterward, I have had the experience to enhance my knowledge and coaching abilities through high-quality training. I not only know how to identify strengths and weaknesses in biomechanics that could lead to injury, but I also understand how to fix these weaknesses by applying a scientific approach to training. My goal is to not only help students excel in their training but to also help educate them and guide them towards understanding their own bodies and movements; why certain approaches don’t work and why other approaches do and how to push their bodies and minds to new horizons in a safe and fun manner.
