Because of the growing need for search and detection dogs because of 9/11 he started a program which was such a success and attracted students from all over the world and preparing them to enter canine related fields including national security, law enforcement, veterinary medicine, canine-assisted therapy and much more. As a professor at SUNY, his students will never forget his teachings and professionalism. He received the Master Trainer Award from the North American Police Work Dog Association in 2017 recognizing him for his work with utility, cadaver, narcotics, and wild life detection dogs and awarded SUNY’s Distinguished Service Professorship Award in 2020. He was a board member of the Northeast Wilderness Search and Rescue and founding member of the New York State Canine Association. He taught decades for the Eden International Police K9 Conference and taught for numerous working dog organizations around the world and wrote K9 training columns for Dog Sports, Working Dog and Police magazines.
