Winnie and Alma are serving among the Matigsalug Tribe in Marilog District, Davao City. They are currently engaged in pioneering ministry, establishing relationships and laying the foundation for a local ministry among the Matigsalug people. They have started regular Bible studies and prayer meetings with one family and some of their relatives, seeking to build a strong foundation for the Gospel in the community.

Their missionary journey began in Benguet, where they were first assigned to reach the Kankanaey Tribe. After seven years of ministry there, God called them to minister among a certain people group in Mindanao in partnership with another organization. When they eventually left the area, they were able to leave behind several believers, while the organization they had partnered with sent a full-time worker to continue the ministry there. They later spent three years reaching another people group in another country in Southeast Asia.

Winnie is originally from Cebu City, while Alma is from Davao City. They have three children: Serwinclod Adriel (Aiel), Jeuel Jabele (Aya), and Mishael Kaey.
