He is a two-time Olympian (2000 and 2004), and currently holds a Guamanian record in the 100-meter butterfly (5505). O'Keeffe made his official debut, as Guam's only swimmer, at the 2000 Summer Olympics in Sydney, where he competed in the men's 100 m butterfly. Swimming in heat two, he posted a lifetime best of 56.05 to take a fourth seed and forty-fifth overall by a hundredth of a second (001) behind Algeria's Mehdi Addadi.
At the 2004 Summer Olympics in Athens, O'Keeffe qualified again for the 100 m butterfly, by receiving a Universality place from FINA, in an invitation time of 56.96. He challenged seven other swimmers on the second heat, including fellow two-time Olympians Conrad Francis of Sri Lanka and Nicholas Rees of the Bahamas. He edged out Aruba's Davy Bisslik to take a seventh spot by 0.46 of a second in 57.39.
O'Keeffe failed to advance into the semifinals, as he placed fifty-fifth overall in the preliminaries. O'Keeffe currently lives in Guam, where he works partly as a sports development officer for the Guam National Olympic Committee, and a president of the Greater Pacific Aquatics.
O'Keefe was also a former member of coach Ron Ballatore's UCLA Bruins swimming and diving team at the University of California, Los Angeles, before returning to Guam in 1995.
