In this episode of EMS One-Stop, host Rob Lawrence sits down with Oscar Monterrosa, the 2026 NAEMT Paramedic of the Year, whose career has taken him from Army combat medic to street paramedic, medical student and now an emergency medicine-internal medicine resident at Hennepin County Medical Center. Yet despite the white coat and demands of residency, Monterrosa continues to work on the ambulance, including in rural Minnesota, and remains closely connected to the profession that shaped his approach to medicine.
The conversation also returns to one of the defining moments of Monterrosa’s career: the Oct. 1, 2017, mass shooting in Las Vegas. Working an overtime special-event shift, Monterrosa was already inside the medical tent when gunfire began and casualties started arriving. He describes slipping into “work mode,” drawing on his experience as an Army combat medic in Iraq as he and others triaged and treated patients while the shooting was still underway.
Beyond that extraordinary night, the discussion explores rural EMS, critical care and ECMO, education, mentorship and the long road from paramedic to physician. Monterrosa’s message to other EMS clinicians considering further education is straightforward: the road may be difficult and it may take longer than expected, but it is possible.
Key quotes from Oscar Monterrosa
- “We have that critical call or whatever, somebody that’s crashing right in front of you and you just kind of get into work mode.”
- “Even though there’s still gunfire going on, you try to be as safe as you can and take cover, but ultimately all that is really out of your control.”
- “A lot of these experiences in the cornfields has been very rewarding, just seeing this different culture, like meeting a lot of different people.”
- “It just takes hard work and just not giving up.” “I was an undergrad for 9 years because I was working full time on the streets.”
