Agencies choose Coastline because we don’t just consult — we walk alongside you as true partners in progress. 

Coastline was founded by Lindsay Slattery-Cerny and Catharine Staniscia, two proven leaders with deep roots in behavioral health, social services, and system-level transformation. With decades of combined frontline and executive experience, they’ve seen what works, what breaks systems, and most importantly — how to rebuild with clarity, compassion, and strategy. 

Here’s why agencies trust Coastline: 

✅ We’ve sat in your seat. 
Lindsay and Catharine aren’t outsiders — they’ve led departments, built programs, and navigated the same funding demands, compliance issues, and staff training needs you're facing. 

✅ We blend expertise with action. 
From hands-on training to policy audits, our solutions are never copy-paste. We tailor each engagement to your mission, team, and capacity — with an eye on sustainable outcomes. 

✅ We value relationships over transactions. 
We're not in this for a quick fix. Coastline is your long-term partner in building stronger systems and deeper impact — with empathy, rigor, and responsiveness at every step. 

✅ We center equity, voice, and community. 
Whether it's cultural competency training, anti-trafficking curriculum, or program design — we ensure your work reflects the communities you serve. 

✅ We make the complex feel manageable. 
Regulations, grants, audits, workforce turnover? Coastline brings clarity, alignment, and confidence back into the process.
