He graduated from De La Salle University with a degree in history and political science.
Political career
His early political career began in the Kabataang Barangay (KB) where he became the president of the provincial KB federation of Pangasinan, chairman of the regional KB federation of Ilocos Region, and member of the KB National Council.[2] From 1980 to 1985, he was a member of the Pangasinan Provincial Board.[1]
Estrella returned to the House of Representatives as the representative of the 6th district of Pangasinan in 2001 and served until 2010. During the 12th Congress, he was the chairman of the House Special Committee on the North Luzon Growth Quadrangle.[1] In 2013, he became the party-list representative of Abono succeeding his brother Robert Raymond Estrella. He was among the 23 representatives linked to the pork barrel scam by a Philippine Daily Inquirer exposé in 2013.[6] The National Bureau of Investigation subsequently named Estrella and his brother in its 2015 report to the Ombudsman among those allegedly involved in malversation, direct bribery, and other graft and corrupt practices.[7] That same year, he was served numerous notices of disallowances from the Commission on Audit with regards to the use of his Priority Development Assistance Fund to implement livelihood projects worth ₱64million in Pangasinan coursed through questionable non-governmental organizations. He was later excluded from liability by the commission in 2018 due to a court decision which declared his signatures in the documents facilitating the transactions to be forgeries.[8]
Estrella married Sandra S. Romero on June 7, 1985, at the age of 24. The couple produced four children: Maria Sergia Susana, Conrado Andrew IV, Albert and Gilbert.[10]
