Dr. Colleen Saringer is a blue-collar woman wrapped in a PhD package who’s on a mission to stop work from hurting people. As a professional speaker on workplace mental health and suicide prevention, she blends 25 years as a Global Organizational Health Leader with a lifetime weathering the challenges of two family-owned construction businesses - one of which nearly ended in suicide. Dr. Colleen brings a rare, inside-out perspective to mental health and culture at work, by educating blue collar industries on the workplace psychosocial risk facts that contribute to and worsen anxiety, depression, suicidal thoughts and suicides. She offers practical suicide-prevention solutions - based on kindness, accountability and boundaries - that protect people and strengthen the bottom line.
