Democratizing High-Quality Medical Education.


Pre-hospital providers, be they EMTs, paramedics, customer service representatives or first response teams, are at the forefront of treating and caring for sick and injured people. However, despite this critical role they do not have good access to patient simulation. Current simulators are bulky, heavy and expensive. Furthermore, we just don't think current "state-of-the-art" mechanical simulators are very realistic.


That's why we created PerSim®.

The PerSim® was specifically designed with pre-hospital training in mind. With highly realistic scenarios designed just for pre-hospital providers and a focus on keeping the PerSim® affordable and portable, we're passionate about bringing a high-quality patient simulator to you to help maintain and improve your skills. Our focus on affordable, portable and realistic simulation is specifically intended to provide all people who can benefit access to this valuable training modality.

We have one focus: bringing affordable, portable and realistic patient simulation to pre-hospital professionals
