He received his MS in Counseling and his MA in School Administration from the University of Phoenix. Brian has worked as a substitute teacher, counselor and middle school assistant principal. Brian loves the Colorado lifestyle but still misses the food and culture of New Jersey (as well as the Yankees and Jets).
