Clinical screening room

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.

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.

The clinicians behind the program.

Board-certified specialists in cardiology, oncology, and behavioral health — each with direct first-responder experience.

Dr. Marcus Halloran

Dr. Marcus Halloran

Board-certified cardiologist, former NYC EMS. Lead author on three peer-reviewed studies of occupational cardiovascular risk in structural firefighters.

Dr. Sarah Whitford

Dr. Sarah Whitford

Medical oncologist with a clinical focus on firefighter-specific cancers. Adjunct researcher with the IAFF Cancer Project.

Dr. Andre Castillo

Dr. Andre Castillo

Former battalion chief turned physician. Built Interceptor after losing two crew members to undiagnosed cardiac disease within the same year.

Dr. Lena Park

Dr. Lena Park

Clinical psychologist specializing in first-responder PTSD, shift-work sleep disruption, and post-incident peer support programs.

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.
