Avantha started teaching swimming in London in 2006, while completing his BSc in Sports Coaching at the University of East London. Over seven years at Greenwich Leisure Centres, he trained under the UK's ASA Level 1 and 2 swim teaching standard and earned his National Pool Lifeguard Qualification — the same rigorous framework used in British schools.
After graduating, he spent two years as a Level 3 certified personal trainer in London before returning home with a single idea: what world-class swim teaching looks like in the UK, every child back home deserves too.
He and Dinethri built Stingrays together — from a single pool in Kandy to 2,100+ swimmers learning every week across 11+ cities, a proprietary Level 1–4 coach training pathway, and partnerships with Trinity College Kandy, Hillwood, Mowbray, and dozens of apartment communities and clubs.
