Hear from the EMTs, A-EMTs, and Paramedics who trained with Dr. Shermer and went on to serve their communities.
Dr. Shermer has a rare gift — he makes the most complex clinical concepts feel approachable without ever dumbing them down. When I was struggling with 12-lead interpretation during my paramedic program, he sat with me after class and walked through every nuance until it clicked. That kind of dedication is something you just don’t forget. I credit his teaching with giving me the confidence I needed on my first real cardiac arrest call.
I was terrified going into my EMT clinical rotations. Dr. Shermer has this calm, reassuring bedside manner that he brings right into the classroom — he teaches the way he practices, with patience and genuine enthusiasm for every question. He never made me feel like my questions were too basic. By the time I passed my NREMT, I felt truly prepared, not just test-ready. I still hear his voice in my head on tough calls.
What sets Dr. Shermer apart is how much he clearly loves what he does. You can feel it in every lecture. He doesn’t just teach protocols — he teaches you how to think like a clinician. During our A-EMT pharmacology module, he used real patient stories to bring drug mechanisms to life. I’ve taken a lot of continuing education courses over the years, but nothing has stuck with me the way his instruction has.
Dr. Shermer is the kind of educator who remembers that behind every protocol is a real patient. His teaching style is warm, conversational, and deeply rooted in clinical experience. He challenged me to think critically rather than just memorize answers, which made all the difference when I sat for my paramedic boards. Years later, I still recommend him to every new provider I mentor. He shaped the kind of medic I am today.
