VICE PRESIDENT Small Urban/ Rural Systems

Mary Habig

Seneca-Crawford Area Transportation

Mary Habig started her Transit Career in 1992 as the Director of a very small county-operated transit system in South Eastern Ohio.  After 9 years, she ventured out of the small transit community and into the For-Profit Transit World for 10 years.  Habig stated, "Though I have enjoyed many aspects of the For-Profit Transit companies, I felt the need to go back to the non-profit transit system. Even though there are more struggles with non-profits, non-profits seem to care more about the service they provide." In 2014, Habig returned to Ohio and assumed the position as the Director of Seneca County Agency Transportation. In 2017, Seneca County Agency Transportation, SCAT, expanded their service area to include Crawford County.  The agency’s name is now:  Seneca-Crawford Area Transportation, SCAT. Habig is in her 28th year of Transit Management and smiles when she looks back and remembers all the great people she’s met throughout the years.  “Seven States, Hundreds of Employees, Thousands of Tears, and Millions of Smiles because of Transit I’d do it all over again!"
