Ed Lesofski

MSW/MS Candidate Dec 2016
Executive Director

Mr. Ed Lesofski holds a Bachelor of Science degree in Law from American Military University and is currently pursuing Master degrees in Exercise Physiology and in Social Work. While completing his undergraduate degree, Mr. Lesofski experienced several of his veteran buddies commit suicide. While attending classes for his Masters of Social Work program, his goal was to train service dogs when an internship with the American Red Cross changed his path. Seeing the need for services in the rural communities, especially veterans in Montana, this provided the catalyst for the CVEMT education program. 

Mr. Lesofski has attended the American Association of Suicidology’s Psychological Autopsy training and he also holds several post graduate certificates in the area of suicide. Currently he provides counseling and crisis intervention to veterans through RIVER.
