Sank grew up in a Buddhist family in Khon Kaen, Thailand. He studied education at Khon Kaen University and as a student got involved with Campus Outreach. In his sophomore year, he came to Christ and was discipled over the next two years.

Sank chose to come on as LEAD staff because he has a desire to grow in His walk with Christ and he desires to use his gifts in teaching and evangelism to help the ministry of Covenant Church of Khon Kaen.
