His company Applied Management Resources (AMR) was a franchisee of Leadership Management Inc. LLC.

He received his CCW in 1998 and enjoyed recreational shooting, but it wasn't until some years later, resulting from an incident at the Church he attends, they began to develop a Security Team which he continues to be a member today.

He is presently developing a Conflict Avoidance, Intervention, and De-Escalation ( AID-R ) course teaching the  Resolution and Defense of unavoidable violent encounters.
