The team
Two founders. One phone call.
Over 30 combined years in behavioral health, child welfare, crisis response, and systems change. When you work with Coastline, you work with us — not a junior team.
Lindsay Slattery-Cerny, MSW
Co-Founder & Consultant
Lindsay Slattery-Cerny, MSW
Lindsay is a Palm Beach County-based social work leader with more than fifteen years of experience spanning frontline practice and systems change across the Treasure Coast. After completing her master’s in social work at Florida Atlantic University in 2012, she served in every tier of the child welfare continuum — case management, forensic assessment, and residential programming — championing trauma-informed, family-centered care.
Personal and professional suicide losses galvanized Lindsay’s commitment to crisis prevention. From 2016 to 2019 she directed the Florida Linking Individuals Needing Care (FL LINC) Project, the region’s first initiative to embed SAMHSA’s Zero Suicide framework, through a partnership with Southeast Florida Behavioral Health Network. As a regional suicide-prevention specialist she became a certified instructor in QPR, QPR-T, and Youth Mental Health First Aid, ultimately training more than 3,000 parents, educators, clinicians, and community leaders.
At Coastline she provides systems-oriented behavioral health consulting and delivers statewide trainings in Zero Suicide, trauma-informed care, grant development, active bystander intervention, and overdose response. She also volunteers as a regional director for the Florida Suicide Prevention Coalition.
