About MEMA
MEMA was created by fleet professionals who saw the value of sharing experience, solving problems together and helping one another adapt to a changing industry.
What began in 2013 as an informal exchange between fleet managers has grown into a professional community connecting public-sector fleet leaders, maintenance professionals and industry partners through meetings, training, resources and peer collaboration.
In 2013, a group of fleet managers began doing something simple: sharing information.
They compared experiences, asked one another questions and helped each other work through the operational challenges they were facing.
Those conversations revealed something important. Many public fleets were tackling the same problems, but they were often doing it independently.
MEMA grew from that realization, with founding leaders including David Worthington and David Renschler helping shape a professional community built around collaboration, shared experience and practical problem solving.
Today, the Municipal Equipment Maintenance Association connects fleet professionals through regional chapters, virtual collaboration, meetings, training, member resources and direct access to peers throughout the fleet community.
The organization has grown, the technology has changed and the challenges have become more complex.
The principle behind MEMA remains the same: when fleet professionals share what they know, everyone gets better.
