Michael Pieroni - Chief Operating Officer

Welcome to Medical Express Ambulance Service. We at MedEx are blessed to work with the very best and most compassionate caregiving team around. As an organization, our work plays a vital role in the healthcare system. As providers, we make a difference in the lives of our patients and their families. The time with our patients can be measured in minutes, while the memory of the care and compassion we deliver lasts forever.

Since beginning my EMS career in Chicago back in the 1980s, I have always taken the time to evaluate any situation, formulate a plan, and “do the right thing.”

As part of the Executive Leadership Team, I assist Lauren in fostering a culture that actively seeks out “the right thing to do.” It is not always easy, it may demand exceptional effort, but we will always try to do what is RIGHT. By prioritizing ongoing training, we ensure that our team is prepared to handle any situation that comes their way. Continuous improvement is essential in the field of emergency medical services, as it ensures that we are equipped with the necessary skills and knowledge to provide the highest level of care.
It is my honor to lead this wonderful team and support all those we serve.

I’m happy to assist you in any way I can. If you have any questions or if there’s anything specific you’d like to discuss, feel free to let me know.
