Greg Halvorson, Operations Director
Having been born and raised in the Valley of the Sun, Greg Halvorson began his journey with Crossroads just minutes from his family’s home, where they moved in 1980 after several years in Southern California. Greg has always been an avid outdoorsman, following in his father’s footsteps. Greg’s dad was a true Arizona hiker and fisherman who spent much time on jeep trails and in the Bradshaw Mountains. Greg fly-fishes regularly and considers the activity therapeutic.
After reaching a point of total surrender in his battle with alcoholism, Greg’s dad gave him the number for Crossroads. “I was finally ready to surrender and follow the lead of those before me,” Greg says. Crossroads gave him the chance, and he found his purpose there.
Greg has held many positions at Crossroads, from volunteer, site manager, Assistant Coordinator, outreach, and Program Coordinator, to now Operations Director. “My favorite part of this job is still, and always will be, talking to the new clients to share some semblance of hope,” he says.
Michael Gelbron, Compliance Director
Over the past 14 years, Michael Gelbron has experienced virtually all there is to experience at Crossroads. His current job is Compliance Director, but he was hired to work in the kitchen back in 2010.
From there, he moved into Operations as an Assistant Program Coordinator in 2016. A year later, Michael was transferred into the Compliance department.
He attended Brophy College Preparatory and Northern Arizona University. Michael is married and is an avid pickleball player.
