About
We exist to stop preventable line-of-duty deaths.
Interceptor Health was founded by clinicians and former first responders who watched too many firefighters die from conditions a blood test could have caught a decade earlier. We are here to change that.
Mission
Early detection. Clinical education. Routine monitoring.
Most on-duty firefighter fatalities are not the fire — they are the cardiovascular event on the way home from it, the cancer caught at stage IV, the suicide nobody saw coming. We believe every one of those is a clinical failure, and we are building the program that closes the gap.
Medical Staff
The clinicians behind the program.
Board-certified specialists in cardiology, oncology, and behavioral health — each with direct first-responder experience.
Dr. Marcus Halloran
Medical Director, Cardiology
Board-certified cardiologist, former NYC EMS. Lead author on three peer-reviewed studies of occupational cardiovascular risk in structural firefighters.
Dr. Sarah Whitford
Oncology & Risk Assessment
Medical oncologist with a clinical focus on firefighter-specific cancers. Adjunct researcher with the IAFF Cancer Project.
Dr. Andre Castillo
Founder & CEO
Former battalion chief turned physician. Built Interceptor after losing two crew members to undiagnosed cardiac disease within the same year.
Dr. Lena Park
Behavioral Health
Clinical psychologist specializing in first-responder PTSD, shift-work sleep disruption, and post-incident peer support programs.
What we stand for
Three commitments.
Evidence over tradition
We use the panels and imaging the literature actually supports for firefighter populations — not the bare minimum that satisfies an annual physical form.
Meet crews where they work
Our diagnostics travel. Mobile units, station visits, group bookings around shift schedules — we make screening easier to say yes to than to skip.
Confidentiality is non-negotiable
Records live with the firefighter, not the department. Aggregate insights inform chief-level briefings; individual results stay between patient and clinician.
