Found David Lim

He's running a swim school - Swimfast. Quite an appropriate name I guess. Fully geared to their objective.

Taken off the site:

Swimfast is headed by David Lim, 2 time Olympian and 19 time South East Asian Games Gold Medallist. Head Coach for the 1995, 2000 World Championships, 1993, 1999 and 2001 SEA Games and 2002 ASIAN Games. Received the Public Service Star Award in recognition of his athletic achievements.

He was a 3 time Singapore Sports Council Sportsman of the Year.

Good job.
