I'm only writing a review because I'm a regular and valued customer and I know that if these amazing instructors became even more in demand, they would always find time for me; otherwise, I'd be keeping them secret :-) These are very special instructors. I've worked with Kat a little bit but work with Rania regularly and I know many people who speak very highly of Serkan. They REALLY understand how your body works, what its capable of, what it needs to heal and to stretch and strengthen. They are hugely respectful of your needs and work hard to get the best out of you. Pilates has changed my life and Rania is a very important part of that story. I'd follow her anywhere.
