A swim school built by coaches.
Not consultants.

Meet Avantha & Dinethri.

A London beginning.

Avantha started teaching swimming in London in 2006, at Greenwich Leisure Centres' Arches Leisure Centre. He was finishing his BSc in Sports Coaching at the University of East London while coaching children and adults through the UK's National Plan for Teaching Swimming — the gold-standard learn-to-swim curriculum used in British schools.

He trained under the UK's ASA Level 1 and Level 2 swim teaching certifications, earned his National Pool Lifeguard Qualification (NPLQ), and spent seven years teaching everyone from two-year-old aqua-tots to adult triathletes. After graduating he worked two more years as a Level 3 Active IQ certified personal trainer in London's Greenwich borough.

Home, with a mission.

In 2013 Avantha came home to Sri Lanka. He didn't return to a job — he returned to a problem: most Sri Lankan children, like most Indian children, never learned to swim. The programs that existed were either expensive private coaching or chaotic school pool time. Nothing in between. Nothing structured. Nothing scalable.

He and Dinethri started with one pool in Kandy. By 2015 they had incorporated. By 2020 they were running programs across multiple cities and in partnership with Trinity College Kandy, Hillwood College, Mowbray College, and a growing roster of apartment communities and clubs.

Where they are today.

Today Stingrays teaches 2,100+ swimmers every week across 11+ cities, making it the largest private swim school network in Sri Lanka. Every instructor is trained through the proprietary Stingrays Level 1–4 pathway — a progression that builds careers, not just a workforce.
