Head of Technology, Overstory Health Founder, Behavioral Health Open Source Author

I build technology infrastructure for behavioral healthcare. The data we handle is therapy notes, substance use records, crisis interventions. The systems that process it should be as carefully built as the care they support.

What I Do

I lead technology at Overstory Health, a behavioral health startup running PHP/IOP programs validated by McLean Hospital. I was employee number one. I built the entire technology platform from scratch: cloud infrastructure, clinical operations tooling, patient communication systems, data pipelines, security architecture, and compliance programs.

Outside of Overstory, I maintain the bh-healthcare open source organization, publishing infrastructure, standards, and tooling for behavioral health technology systems. Audit schemas with HIPAA compliance mappings. FastAPI middleware for PHI-safe event emission. Clinical safety signal detection. All Apache 2.0. All designed so small and mid-sized BH organizations don't have to reinvent the wheel on compliance infrastructure.

I am also writing a book on neurodivergent leadership in technology, and I serve as Privacy Officer at Overstory Health, responsible for HIPAA compliance, security architecture, and vendor governance across the organization.

What I Care About

Behavioral health is one of the most operationally complex and technologically underserved sectors of US healthcare. The tools are fragmented, interoperability is poor, workflows are manual, and the data infrastructure gap is massive. I believe better technology makes better care possible, and that the infrastructure to build it should be open, reusable, and accessible to organizations that need it most.

I also care about building teams where people can be themselves. I have ADHD. I lead with that, not despite it. If you want to know more about that, the book gets into it.

If you are building in behavioral health, working on healthcare compliance infrastructure, or interested in neurodivergent leadership, I would genuinely love to connect. Find me on LinkedIn or through the bh-healthcare GitHub org.
