The Bears on Tuesday announced that new head coach Matt Nagy has finalized his staff.
The offense will be led by coordinator Mark Helfrich and position coaches Dave Ragone (quarterbacks), Charles London (running backs), Mike Furrey (receivers), Kevin Gilbride (tight ends) and Harry Hiestand (line). Ragone is the lone offensive position coach to be retained from John Fox's staff.
Other staff members on offense include Donovan Raiola (assistant line), Mike Snyder (quality control), Brian Ginn (quality control) and Shane Toub (assistant), the son of former Bears special teams coordinator Dave Toub.
In addition, veteran coach Brad Childress will serve as a senior offensive consultant.
The defensive staff returns intact from last season, led by coordinator Vic Fangio and position coaches Jay Rodgers (line), Brandon Staley (outside linebackers), Glenn Pires (inside linebackers) and Ed Donatell (defensive backs). Roy Anderson (assistant defensive backs) and Sean Desai (quality control) also return, while Bill Shuey (quality control) has joined the staff.
The special teams will be operated by coordinator Chris Tabor and assistant Brock Olivo.
Jason Loscalzo has been hired as head strength and conditioning coach. He served in the same position at Washington State the past six seasons.
Andre Tucker has also joined the Bears as head athletic trainer. He spent the last eight seasons as assistant athletic trainer with the Cleveland Browns.
Here's more information about some of the additions:
Mark Helfrich (offensive coordinator)
Helfrich led Oregon—known for its explosive record-setting offense—to a 37-16 record in four seasons as coach from 2013-16, including a 24-12 mark in the Pac-12.
In 2014, Helfrich guided Oregon to a school-record 13 wins, a Pac-12 championship, a Rose Bowl victory in the inaugural College Football Playoff semifinal and an appearance in the CFP national championship game. As a result, Helfrich was a finalist for the Eddie Robinson and Maxwell Football Club Coach of the Year awards.
Also that season, quarterback Marcus Mariota became the first Oregon player to win the Heisman Trophy. A few months later, Mariota was selected by the Tennessee Titans with the second overall pick in the 2015 NFL Draft.

Helfrich became Oregon's head coach after spending four seasons as the school's offensive coordinator and quarterbacks coach under Chip Kelly from 2009-12.
During that span, the Ducks played in four straight BCS bowl games and won three consecutive Pac-12 championships. Under Kelly and Helfrich, Oregon's offense averaged 44.7 points and 283.4 yards rushing while putting up more than 500 yards of total offense per game.
Charles London (running backs)
London has spent nine seasons in the NFL, including the last four as the running backs coach for the Houston Texans. He returns to Chicago after serving as an offensive assistant with the Bears under head coach Lovie Smith from 2007-09.
In Houston, London coached a proficient ground game that helped propel the Texans to back-to-back AFC South championships in 2015-16 and three straight winning seasons for the first time in franchise history.
Mike Furrey (receivers)
Furrey played seven NFL seasons as a receiver and safety with the Rams (2003-05), Lions (2006-08) and Browns (2009). The Northern Iowa product appeared in 94 games with 41 starts, catching 221 passes for 2,298 yards and seven touchdowns and recording four interceptions and 10 pass breakups.
Furrey spent the past seven seasons coaching at the collegiate level as head coach at Kentucky Christian (2011-12), receivers coach at Marshall (2013-15) and head coach at Limestone College in Gaffney, S.C. (2016-17).
Kevin Gilbride (tight ends)
Gilbride spent the last eight seasons with the New York Giants, including the last four as their tight ends coach.
In New York, he demonstrated a knack to develop young players. Last season, Evan Engram led all NFL rookie tight ends in receptions (64) and yards (722) and tied for first in touchdown catches (six). Engram also led the Giants in receptions and touchdown catches and finished second in receiving yards.
Harry Hiestand (offensive line)
Hiestand returns to the Bears for a second tour of duty. He first served in that capacity for five seasons from 2005-09 under Smith, helping the Bears win back-to-back NFC North titles and reach Super Bowl XLI in 2006.
During that time, Hiestand played a key role in sending center Olin Kreutz (2005 and 2006) and guard Ruben Brown (2006) to the Pro Bowl. Kreutz was also named first-team All-Pro in 2006, the first Bears offensive lineman to accomplish that feat in 17 years.
Hiestand has spent the last 29 seasons as an offensive line coach, mainly at the collegiate level, including the last six years at Notre Dame. His other stops have included Cincinnati (1989-93), Missouri (1994-96), Illinois (1997-2004) and Tennessee (2010-11).
Brad Childress (senior offensive consultant)
Childress has spent 19 seasons as an NFL coach, including a stint as head coach of the Minnesota Vikings from 2006-10. Childress worked with Nagy the past five seasons with the Kansas City Chiefs.
Chris Tabor (special teams coordinator)
Tabor returns for a second stint with the Bears after serving as assistant special teams coach under Toub on Smith's staff from 2008-10.
Tabor spent the last seven seasons as the Browns special teams coordinator. During his tenure, Cleveland ranked sixth in the NFL in kickoff return average against (21.8), seventh in punt return average (9.9), ninth in total kick return yards (8,974) and 10th in total return yards allowed (7,627).
Brock Olivo (special teams assistant)
Olivo joins the Bears after serving as the special teams coordinator with the Denver Broncos last season. Prior to that, Olivo worked alongside Nagy in Kansas City from 2014-16 as the Chiefs' assistant special teams coach.
