Welcome to COMTO Washington State
Ensuring Transportation Serves All
COMTO’s mission is to provide full access to employment, career and contract opportunities for veterans, adults with disabilities, women, and people of color within the transportation industry. Over the past fifty years, our mandate has evolved to include not only public transportation industry executives, but also professionals at every level of industry encompassing a variety of fields and disciplines. Now, as was then, members are encouraged to share information, opportunities and personal expertise. With 40 chapters throughout the United States, our mission is as relevant today as we strive to provide full access to employment, career and contract opportunities for people of all lived experience within the transportation industry. In March 2017, a small group of public and private sector professionals committed to COMTO’s mission founded the Washington State chapter of COMTO as the 32nd chapter in North America.
