Elvin and Esther Foong are full-time itinerant families and kids' ministers, and the founders of The Treasure Box Singapore, a products and services company that aims to help families grow closer to God and to each other. They have been married for 15 years, and are proud parents to Nathan (12) and Phoebe (10). Elvin and Esther believe that every parent's first ministry is to their home - and their first disciples are their own kids.
