Kosta DoulfisTrainer
I’ve been swimming for over 19 years and spent several years in competitive swimming at the top level, including participation in three international tournaments.
I’ve been teaching swimming for years — began with diploma-level lessons for children and now focusing mainly on teaching and sharing my knowledge to improve competitive strokes.
I adjust my coaching to every level, from beginners to advanced swimmers, and I enjoy using my experience to help others grow in the water.
