About Us

We want to reinvent the cultural understanding of safety in hospitals and clinics.


We address a controversial topic: healthcare professionals deal with the same people that law enforcement deals with, without the expectation of being able to deal with the same physical threats. It is NOT okay for patients to be aggressive to staff.

At My Occupational Defense, we’re passionate about keeping you safe. With our backgrounds in security administration and the medical field, and we have seen, observed, and experienced workplace violence that occurs so frequently in healthcare.


Based on what we've encountered in our careers, we've designed a curriculum of hands-on classes to help healthcare professionals like you stay safe at work by equipping you with the knowledge of defense psychology and the physical self defense training needed to protect yourselves.

Founder, Safety Consultant, and Instructor Trainer

Jimmy is currently a practicing, board certified Emergency Medicine physician. In addition to clinical medicine, Jimmy has taught martial arts and self defense across the country for over 15 years from Saint Louis to New York. He has helped train law enforcement, private security, and amateur fighters. Seeing a disparity in physical safety for Emergency Department nurses, doctors, and technicians, Jimmy has combined his experiences in the ER with that of self defense with the hopes of keeping hospital staff safe and able to keep caring for the sick.
