BOISE, Idaho – Athletic Club Boise announced on Friday it had appointed Nate Miller as the first Head Coach in the club’s history. Miller joins the 2026 USL League One expansion club from Real Salt Lake of Major League Soccer, where he served as an assistant coach on Head Coach Pablo Mastroeni’s staff.

Widely respected for his leadership, tactical insight, and player development track record, Miller will lead Athletic Club Boise into its inaugural USL League One season in 2026.

“What drew me to Boise was the chance to build something meaningful — not just a team, but a club that truly connects to its city,” said Miller. “I love building — teams, cultures, environments that have a clear identity and a shared purpose. That’s what drives me as a coach.”

“Nate is the ideal head coach for a new soccer organization,” said Jeremy Fishbein, Vice President of Soccer, Athletic Club Boise. “He brings a broad base of experience across every level of the American game — from the collegiate ranks to the MLS sideline. He’s a proven educator and developer of elite players.

“Nate understands creating pathways for players and provides a holistic approach to coaching. We’re thrilled to have him guiding our fi rst team and helping us shape an ambitious club that not only seeks to win championships but also impacts the Boise community.”

Miller has held leadership roles in MLS, the USL Championship, and collegiate soccer. Prior to joining Real Salt Lake, he was head coach of San Diego Loyal SC, guiding the club to a 16-9-9 record and a berth in the 2023 USL Championship Playoffs.

He previously led Lansing Ignite to a second-place finish in USL League One’s inaugural season in 2019 and an appearance in the League One Playoffs before joining the staff at SD Loyal, where he served as an assistant coach prior to leading the side in 2023.

“I’ve been fortunate to coach at every level in American soccer, and what I’ve learned is that real success happens when ambition and purpose align,” said Miller. “From the start, it was clear this club means it – they’re committed to competing at a high level and building something that lasts. That kind of belief and alignment made this the right place and the right time.”

Miller began his coaching career at the collegiate level with Spring Arbor University, where he posted an 82-33-14 record and earned conference Coach of the Year honors. Known for an attack-minded, high-intensity style of soccer, Miller emphasizes proactive play, relentless team eff ort, and a clear identity built on connection and purpose.

“I want to win,” said Miller. “That’s always been my passion — helping players and teams push toward championships and building a club that can grow into one of the top teams in the country. That work starts now. We’re laying the foundation to compete from day one and to keep climbing every year.

“I’m grateful to Real Salt Lake – to Pablo, the team, and everyone there – for the experiences and trust they’ve given me. Now I’m ready to take what I’ve learned and help build something special here. My family and I can’t wait to make Boise home.”
