Ferrigno replaces Bert Bertero, who stepped down in January to focus on teaching history at the school. Bertero coached the Panthers for three years, guiding them to a 15-15 record.
In addition to his three stints at Cal (1980-81, 1996-99 and 2006-07), Ferrigno has also coached at Oregon, USC, Oregon State, Western Michigan, Pacific and San Francisco State.
He last worked on the high school level in 1977 as an assistant at St. Ignatius-San Francisco.
"It was just a good opportunity for me and my family," Ferrigno said Thursday. "I really agree with a lot of the things that are going on at St. Mary's."
Ferrigno was an All-American as a wide receiver at San Francisco State and signed as a free agent with the Denver Broncos. He is a member of the San Francisco State Athletic Hall of Fame, the San Francisco Prep Hall of Fame and the Riordan High School Athletic Hall of Fame.
Ferrigno will teach physical education in addition to his coaching duties. He coached at Cal three separate times and left the Bears in January.
Lowell replaces Darin Owens, who coached the Broncos for one year. Owens left Northgate for a coaching job out of state
Lowell coached with Owens for three years at Martin Luther King-Riverside in addition to the one year at Northgate. Before that, he assisted at West Valley-Hemet, and this will be his first varsity head coaching job. Lowell is 29 years old.
"We felt like we got started on the right page last year," Lowell said. "We got the kids to buy into the program and to buy into the offense and defense and the things we're doing. We're going to try to keep the momentum and enthusiasm going."
Lowell has worked predominantly on the defense but he said he will continue to use the double-wing, double-tight-end offensive attack that Owens installed last season.
"(The players) found some success with it last year," Lowell said of the run-based offense. "They believe in it and they feel it's something they can win games with."
Last year, the Broncos snapped a 13-game losing streak dating back to 2005 when they defeated Tamalpais 63-0 to begin the season.
SIGNING: After making the most of his only season of high school football, De La Salle defensive back Travis Carrie has accepted a scholarship offer to attend Ohio University in the fall.
"I went there for a visit and just felt very comfortable," Carrie said on Thursday. "It's a place where there won't be a lot of distractions and I can focus on school and football."
Carrie, who was sidelined with a heart condition during his first three years of high school, became an impact player for the Spartans this past season. He finished the year with 41 tackles, two forced fumbles and two interceptions. He was arguably the MVP of the Spartans' victory in the California Interscholastic Federation Division I championship, scoring a pair of touchdowns on offense and making an acrobatic interception that set up a third touchdown.
Ohio is part of the Mid-American Conference and went 6-6 last season.
