In this video, Chelsea (our AI virtual assistant) will tell you more about the company.
Chelsea Gymnastics Academy was founded by its Director and owner, Dr Stefan Kolimechkov in 2022. Chelsea Gymnastics Academy is the successor of Stefan's sole trade gymnastics coaching business called STK SPORT (operating in London between 2013 and 2022). Chelsea Gymnastics Academy brings gymnastics to the community in homes and studios in the Royal Borough of Kensington and Chelsea, London. Our Head Office is registered at Niddry Lodge in Kensington, London. Group Classes are run at St Philip's Church, W8 6QH. Personal sessions are run at The Kensington Studio (W8 6JP), The Revival Studio in Hammersmith (W6 0JN), and in client's homes.
We are listed on the Companies House register, the Information Commissioner’s Office (ICO) register, and we are registered with HMRC.
We provide bespoke personal gymnastics sessions and group general gymnastics classes. We are a club member of British Gymnastics (The National Governing Body for gymnastics in the UK), a CIMSPA employer partner (CIMSPA is the professional development body for the UK’s sport and physical activity sector).
We were a REPs business partner (originally, REPs was the Register of Exercise Professionals in the UK), but we (and many Personal Trainers in the UK) were scammed by them in a deplorable subscription scam in September 2023. Be aware of this brand, now called REPs International!
