Pearl City Aquatics, Inc . was founded by Head Coach Ken Suenaga in 1968. They first held practice at the Momilani Recreation Center with only 14 swimmers. After a year at the Momilani Recreation Center, they moved to the Pearl City District Park Pool. In 1975, PCA grew to approximately 106 swimmers and 5 coaches, who practiced at three different pools – Pearl City District Park Pool, Manana Neighborhood Park Pool, and Momilani Recreation Center Pool.  One of the highlights of that same year was PCA winning the high point team trophy at the First Annual Soichi Sakamoto Invitational Swim Meet on Maui.

In 2003, Head Coach Ken Suenaga's dreams of having an aquatics center worthy of Olympic and international competition on Oahu was realized with the opening of the Veterans' Memorial Aquatics Center (VMAC) in the Patsy T. Mink Central Oahu Regional Park.  The club now utilizes both VMAC as well as Waikele Community Park Pool and Shigeo Ushiro Manana Neighborhood Park pool.  (See Facilities)
