Mike McCarthy’s first coaching staff is officially complete.

The Pittsburgh Steelers on Thursday announced a 26-person staff with 20 assistant coaches, four strength and conditioning personnel and a chief of staff. Many of the hires were previously announced by the team, but one late addition was tight ends coach Robert Kugler, a North Allegheny graduate.

He joins a Steelers offensive staff led by coordinator Brian Angelichio that includes Tom Arth (quarterbacks), James Campen (offensive line), Ramon Chinyoung Sr. (running backs), Adam Henry (wide receivers), Frank Cignetti Jr. (senior offensive assistant), Jahri Evans (assistant offensive line), Tim Berbenich (game management/quarterbacks) and Eric Simonelli (offensive quality control).

Defensive coordinator Patrick Graham is joined by Joe Whitt Jr. (assistant head coach/secondary), Jason Simmons (defensive pass game coordinator/defensive backs), Domata Peko (defensive line), C.J. Ah You (outside linebackers), Scott McCurley (inside linebackers), Shawn Howe (defensive assistant) and Pat Reilly (defensive assistant).

Special teams coordinator Danny Crossman is joined by Derius Swinton II (senior special teams assistant).

Mark Lovat is the team’s head strength and conditioning coach. Lovat is joined by Grant Thorne (director of performance integration/sports science), Justus Galac (strength and conditioning assistant) and Abe Munayer (strength and conditioning assistant).

Steve Scarnecchia is the chief of staff, a newly created position under McCarthy.
