Grace Church has been the home of worship, growth and learning for my wife Shehani, son Sheran and I over the last 12 years. We have been abundantly blessed by various ministries of Grace Church. Glorifying Him through praise and worship has been my humble and primary calling, which I engage with passion. I strive to be an example of the love that God bestows on us. Whether it is on the sports field refereeing soccer games or leading worship, my goal is to serve. I work as a Financial Analyst for Ernst and Young in Los Angeles.
