Elected through the Barangay and Sangguniang Kabataan Elections, Thelmo Opiz Reyes is serving the current four-year term established under Republic Act No. 12232, which extended the barangay official's term from three years to four.

A Philippine barangay's Sangguniang Barangay is composed of one Punong Barangay, seven Sangguniang Barangay Members (kagawads), a Sangguniang Kabataan (SK) Chairperson representing the youth sector, a Barangay Secretary, and a Barangay Treasurer. Together, these officials administer the smallest unit of Philippine local government and deliver frontline services — from barangay clearance issuance to peace and order, from public health assistance to the barangay's share of the Internal Revenue Allotment.
