Ryan Diedrick

Ryan Diedrick joined the San Diego football coaching staff in June 2025 as a wide receivers coach and passing game coordinator. He will enter his first season with the Toreros this fall.

A native of Sammamish, Washington, Diedrick came to San Diego from the Colorado School of Mines, where he worked as a wide receivers coach in 2017, 2018, and 2021 before being elevated to pass game coordinator and wide receivers coach for the 2022, 2023, and 2024 seasons. In 2019, Diedrick was the wide receivers coach at Northern Colorado University. 

While in Colorado, his Orediggers ranked in the top five nationally in total offense on four occasions, including being the country’s most productive Division II team in both 2018 and 2022. His teams ranked in the top-5 in team passing efficiency offense in Division II four times (No. 2 in 2022, No. 3 in 2023, No. 4 in 2018, and No. 5 in 2021), and he orchestrated a top-10 passing offense in Division II four times (No. 1 in 2018, No. 2 in 2022, and No. 6 in 2023). 

Mines posted a stellar 47-9 (.839) record during his tenure, a stint that included four Rocky Mountain Athletic Conference Championships (2018, 2021, 2022, and 2023), three straight NCAA Super Region IV titles (2021, 2022, and 2023), back-to-back NCAA Division II National Runner-Up finishes (2022 and 2023), and one season that ended as an NCAA Division II National Semifinalist (2021).

While in Colorado, he mentored some of the Orediggers’ all-time best players, including all-time statistical leaders and All-Americans Brody Oliver and Max McLeod, and All-Americans Josh Johnston and Flynn Schiele. Under Diedrick, four Oredigger receivers produced seven 1,000-yard seasons; Oliver in 2018, Johnston and McLeod in 2022, and McLeod and Flynn Schiele in both 2023 and 2024. In 2024, Mines became just the second school in college football history to have three consecutive seasons with a 1,000-yard receiving duo. All told, the top three all-time touchdown reception producers in Mines history have been coached by Diedrick. In 2023, Diedrick helped McLeod lead the nation in receiving yards as he broke the Mines records for both receptions (115) and yards (1,656) in a season, earning consensus first-team All-America honors. 

Diedrick first came to Mines from Indiana State, where he served as an offensive analyst, video coordinator, and in an offensive quality control position in 2016. He coached wide receivers at Mines in 2017 and 2018 before Northern Colorado in 2019. A 2016 graduate of Willamette University, Diedrick served as a student assistant as a senior after retiring during his junior year from playing as a quarterback and wide receiver. He was also a recruiting intern at Willamette.

Four players that Diedrick has coached have gone on to play professional football, including Robert Tonyan Jr., who has spent time on the Green Bay Packers’, Chicago Bears’, and Minnesota Vikings’ active rosters.

Diedrick earned his degree in economics from Willamette and has a master's in mineral and energy economics from Colorado School of Mines. 

He is joined in San Diego by his wife, Paige, and daughter, Rose.
