Nicknamed "The Fortune Cookie" (a pun on his name and ethnicity) during his playing days, he was notable for his trademark turnaround fadeaway jump shot.

Co first played in the PBA on April 22, 1975, scoring 34 points and leading Crispa to a 113-102 win over CFC, the team's first victory after starting the season with three straight defeats.

During his PBA stint, he played for the two-time grand slam champion Crispa Redmanizers from 1975 to 1984, with him as one of the team's top scorers.

Co ventured into television and films after his playing days were over, first as a co-host for the noontime show Student Canteen over at RPN (now RPTV), and started alongside action stars like Phillip Salvador in films such as Delima Gang in 1989.

He made a career mostly out of playing supporting roles in films and television series.
