Hired March 10, 2023, Rob Grosso begins his first season as an offensive quality control coach for Green Bay, where he will work primarily with the tight ends. Grosso comes to the Packers after serving as a defensive quality control coach for the Arizona Cardinals for four seasons (2019-22), where he assisted with the defensive backs.

In 2022, Grosso (GROW-so) was part of a defensive staff that helped Arizona rank No. 2 in the league in yards allowed per completion (10.10), the top single-season mark by the Cardinals since the 1970 AFL-NFL merger. Arizona allowed only 40 completions of 20-plus yards on the season, tied for No. 3 in the league. S Budda Baker earned his fourth straight Pro Bowl selection, the only safety in the NFL to be named to the Pro Bowl in each of the last four seasons (2019-22). In 2021, the Cardinals ranked No. 7 in the NFL in takeaways (27) and No. 8 in offensive points allowed (349), and S Jalen Thompson was one of only three defensive backs in the league to post 100-plus tackles (team-high 120), three-plus INTs (three) and five-plus passes defensed (seven).

In 2020, Grosso was part of a staff that helped the Cardinals rank No. 10 in the NFL in passing defense (226.4 ypg) as CBs Patrick Peterson and Dre Kirkpatrick both posted three INTs. Second-year CB Byron Murphy Jr. registered two sacks and two fumble recoveries, one of only two CBs in the NFL in 2020 to post multiple sacks and multiple fumble recoveries as he became the first Cardinals CB in team history (since 1982) to accomplish that feat in a season.

Grosso came to Arizona after spending the 2018 season with the Denver Broncos as the assistant to the head coach under Vance Joseph. Grosso also assisted with the team's outside linebackers and special teams. For the first time in team history, the Broncos featured two players with 12-plus sacks as OLBs Von Miller (14½) and Bradley Chubb (12) both hit that mark. Grosso was elevated to that position after serving as an operations intern with the Broncos in 2017.

Grosso worked with the Arizona Rattlers of the Indoor Football League during the 2017 season as a coaching/player personnel intern. He got his start in the NFL with Denver as a training camp operations intern (2015-16) before working as a volunteer assistant scout with the Saskatchewan Rough Riders (2016-17) and as a scout for Sports Info Solutions in 2016. His first coaching experience came at his alma mater, John Carroll University, in 2014-15 when he served as a student coaching/recruiting assistant.

Grosso played wide receiver at John Carroll for three seasons (2011-13) and earned his bachelor's degree in business administration and management from the school in 2015. He attended Bishop Timon-St. Jude High School in Buffalo, N.Y., where he played football and lacrosse.

Grosso was born on Sept. 22, 1993, in Buffalo, N.Y., and grew up in Lackawanna, N.Y.
