Jim Polster is excited and proud to join the ACT Volleyball Club for the upcoming season. Before ACT, Jim joined the University of the Pacific's Volleyball Program as a volunteer assistant coach in 2013. He took over as a full-time assistant coach in the spring of 2016.

In his five years with the Tigers, he was tasked with working with Pacific's defensive players and primary passers. 

With Polster's help, Pacific put together one of its finest defensive seasons in program history in 2014 as the Tigers finished the year ranked No. 10 in the nation in opponent hitting percentage by allowing a measly .145 average against. Of 31 opponents on the year, the Tigers held 11 to sub-.100 hitting and five to .000 or worse. 

Joining Team USA in 2001, Polster was a part of the American's victories at the NORCECA Continental Championship and Americas' Cup in 2007 as well as taking home a silver medal at the Pan American Games and a bronze at the FIVB World League. He was a two-time Olympic Alternate for the games in Athens and Beijing.

While at Long Beach State, Jim earned second-team All-America honors by the American Volleyball Coaches Association (AVCA) in 2001 as well as being named to the All-Mountain Pacific Sports Federation third team as a senior. Polster earned All-MPSF honors in all four years of action for the 49ers as one of the top outside hitters in the top conference in the nation.

Aside from his time playing for Long Beach State and USA Volleyball, Jim played 10 years internationally in Italy, Russia, Greece and Puerto Rico.
