Beginning his sixth season (no season was held in 2020 due to Covid-19) as the head coach, Dean Grosfeld has led the Falcons to four postseason bowl wins. After the 2020 season was cancelled, Grosfeld and the Falcons came back in 2021 and went 6-5 on the year, which included a 32-14 win over San Diego Mesa College in the Western State Bowl. They followed that up with an 8-3 campaign in 2022, culminated by a 35-28 Western State Bowl win over Long Beach City College. Previously, they ended the 2019 season with a thrilling 46-39 win over Ventura College in the Joe Kapp Real Estate Beach Bowl, while 2018 saw the Falcons post a 21-9 win over Golden West College in the Southern California Bowl.

Grosfeld, a local product from St. John Bosco High School, was a wide receiver that played in the CIF Championship game at Angel Stadium in his sophomore season. He moved to quarterback his junior season and was named his team's captain and threw for 460 yards against Long Beach Poly. He earned All-Del Rey League honors while receiving his team's Coaches Award and was their captain.

After high school, Grosfeld came to Cerritos, where he set the school's single-season passing record at 1,917 yards (since broken). Playing on the 1991 Mission Conference Championship team, Grosfeld was named All-Mission Conference as well as earning the team's Captain Award and Offensive BYA of the Year Award. After Cerritos, Grosfeld earned a scholarship to Utah State University, where he was their captain and guided his team to the the Big West Championship and won the Silver Bowl.
