When Carolyn Bradfield's daughter Laura died from a drug overdose just days before Christmas in 2017, she made it her mission to help other families avoid the same tragedy. Bradfield, a St. Petersburg resident, brought her background in technology and behavioral health to create a better path forward for individuals leaving treatment. She founded InterAct LifeLine, which evolved into Pathroot Health in January 2025 — a change that reflects the platform’s expanded focus and capabilities.

Pathroot Health now helps providers, payers, and employers deliver value-based care by keeping individuals and families connected after treatment. The platform uses wearable data, breathalyzer results, digital check-ins, surveys and engagement tracking to detect early signs of relapse risk, enabling proactive support and intervention. While overdose detection remains part of the long-term roadmap, today Pathroot is focused on preventing relapse before it happens — empowering recovery through smart, personalized monitoring and family engagement.
