Our Story & Mission

In February 1998, Lauren Rubinson launched an ambulance service with a card table, a telephone, and two ambulances parked outside a Chicago storefront. MedEx just celebrated its 25th year!

After 13 years of working for private ambulance providers, Lauren Rubinson believed in a better way to provide exceptional care for patients, employees, and families. That’s why she created MedEx - an ambulance service dedicated to personalized emergency care and improved company culture.

Employees Come First

From the start, Rubinson wanted MedEx to be different. Rather than focusing on trucks and equipment, she emphasized culture, employees, and strengthened relationships. “It’s a high-stress business,” said Rubinson, “To be successful, you have to take care of your employees, and in turn, they’ll take care of your customers. And with a shortage of EMS professionals around the country, it’s crucial for our company to be recognized as a great place to work.”

Believing in Yourself and Your Vision

In a recent Chase Bank newsletter, Rubinson explained that creating MedEx wasn’t something that she wanted to do. “Creating MedEx was something I needed to do,” she said. “And being a woman was never a disadvantage: If you can do a better job, it doesn’t matter if you’re a man or a woman.”

Rubinson likes to spread positive messages and believes in the power of positive thinking. “Even in those early days when we stared at the telephone praying for it to ring with a transport request, I told the team that our plan for MedEx will work.” That was twenty years ago, when MedEx conducted three transports a day. Over 25 years later, MedEx averages more than 200 transports a day!
