Dan Williams enters his seventh season with the Chiefs in 2025, and his third season as assistant quarterbacks coach after serving as the offensive quality control/assistant quarterbacks coach for two seasons. Williams served one season as an offensive assistant in 2022. Williams spent his first two seasons with the Chiefs as the assistant to the head coach (2020-21) and spent the 2019 season as a coaching intern. Williams has now been a part of three Super Bowl wins (LIV, LVII and LVIII) in five years, including back-to-back championships (LVII and LVIII), and three-straight appearances (LVII, LVIII and LIX).
Williams continued to assist the quarterback's unit in 2024 led by QB Patrick Mahomes. Mahomes spearheaded the offense throwing for 3,928 yards on 392 completions, giving him a .675 completion percentage, a career high, which helped guide the Chiefs to a franchise best 15-2 regular season record. With the help of Williams and the offense, the Chiefs made their third-straight Super Bowl appearance (LVII, LVIII and LIX) which is also the team's fifth Super Bowl appearance in six years.
In 2023, Williams worked closely with Quarterback's Coach David Girardi and the rest of the quarterback room. Williams worked closely with QB Chris Oladokun throughout the season and assisted QB Patick Mahomes to earn his third Super Bowl MVP (LIV, LVII and LVIII) after defeating the 49ers 25-22 in overtime in Super Bowl LVIII. Mahomes had another standout year throwing for 4,183 yards on 401 completions with 27 touchdowns.
Williams worked closely with the quarterbacks in 2022 in his sole season as an offensive assistant. With Williams' assistance, QB Patrick Mahomes and the Chiefs offense produced a historic season en route to their second Super Bowl victory in four years (LIV, LVII). Mahomes and the offense led the league in many categories: passing yards (5,250), passing touchdowns (41), passing TD percentage (6.3%), passing first downs (272) and pass plays of 25+ yards (49). Mahomes completed 435 of his 648 passes and his 67.1 completion percentage was the highest of his career so far. The sixth-year quarterback set franchise records for passing yards (5,250) and single-season passing first downs (272) in 2022. Mahomes' 2022 performance earned him his second NFL MVP and Super Bowl MVP after the Chiefs took down the Eagles 38-35 in Super Bowl LVII.
In 2019, Williams worked closely with the quarterbacks and tight ends, gaining experience as a coaching intern of Super Bowl LIV Champion Chiefs before moving to his role as assistant to the head coach. During his time as assistant to the head coach, Williams worked directly with Head Coach Andy Reid in organizing the day-to-day operations of the team. His responsibilities included overseeing player and staff communications with the head coach and managing the football calendar, which includes the offseason program, mini-camp and in-season schedules.
The Sicklerville, N.J., native spent four seasons (2015-18) at Stevenson University where he served as the starting quarterback and team captain. Williams left the Mustangs as the school's all-time leader in career completions (482), attempts (755), completion percentage (64%), passing yards (6,812) and passing touchdowns (57).
