U.S. Soccer Wednesday announced the newest appointments to the U.S. men’s national team technical staff.

Former U.S. international Josh Wolff joins as an assistant coach, B.J. Callaghan as strategy analyst and assistant coach, Steve Tashjian as head performance expert and Darcy Norman as movement and conditioning coach.

Wolff and Tashjian worked under USMNT head coach Gregg Berhalter in the same roles with Columbus Crew SC. Callaghan joins the MNT staff after serving as an assistant coach with the Philadelphia Union, while Norman most recently worked as the performance data analyst and fitness rehab coach with Germany’s men’s national team.

“In putting together the staff, we looked for coaches with considerable backgrounds in four different areas: World Cups, Concacaf, MLS and Europe,” Berhalter said. “This group checks those boxes, and we are confident their wealth of experiences will be beneficial to the players and for the development of our program.”

“From the outset, we searched for coaches that have complimentary skillsets and varied career paths,” USMNT general manager Earnie Stewart added. “Starting with Gregg and with these additions to the staff, we have assembled a strong group that can now begin to implement the culture, style of play and identity we envision for the National Team moving forward.”

In addition, Nico Estevez, who worked closely with Berhalter at Columbus, will join the staff as an assistant coach pending approval of his U.S. work permit. A native of Spain, he holds a UEFA Pro License and has more than 15 years of experience coaching at the highest professional levels in Spain and the United States, including stints at Columbus and La Liga’s Valencia.

Oregon State University men’s head coach Terry Boss, who once was with the Red Bulls, is serving as goalkeeper coach during the January Camp.
