The APY Choir bids Mr. Carlo Serrano goodbye as he resigns from his position as conductor. Mr. Serrano passes on the baton to Mr. Mark Abesia. Mr. Abesia takes on the reigns officially on 28 July 2013.

Mr. Serrano is a Composition Major in the University of the Philippines College of Music. He has selflessly served the group in these various capacities during this period. Mr. Carlo Serrano has been with the group since 2010. He has led the choir through the Panunuluyan Musical Play (2009), Juveleum Youth Festival (2011), the participation of the choir in the Sari-Sari UA&P Chorale Festival (2013), and most importantly during the various church services at the parish. Carlo pushed for musical education for deeper musical appreciation and interpretation of the members, to the point that he even would tutor the members one by one.
