More about Mike

Mike Sosa joined ASCE Texas Section as the Data Coordinator in June of 2017. He is very detail-oriented and has experience working with member-driven associations. He enjoys interacting with members of the Section and helping them benefit from the Section’s resources.

Prior to joining ASCE Texas Section, he spent time working as an executive assistant for companies located in Columbus, OH and San Diego, CA. He is a 2010 graduate of the College of Business at Ohio University with a B.S. in Sport Administration. Before that, he was raised in sunny San Diego and spent the vast majority of his free time on a baseball field or at the beach.

Shortly before joining the team at the Section Office, Mike relocated to Austin from Columbus, OH with his girlfriend, Keah, and their adorable Pitbull/Lab puppy, Nollie. Since moving to Austin, they have expanded the family by adopting a two-year old Australian Cattle Dog named Ziggy.

Outside of work he enjoys finding new places around town to try unique craft beer, catching a baseball or football game on the weekend, exploring local parks and trails with his dogs, and playing slow-pitch softball or a round of golf on a nice Sunday afternoon.

Mike is also an avid fan of the San Diego Padres, San Diego Chargers (he knows they moved, but he refuses to acknowledge the change), New York Yankees, Oklahoma City Thunder, and the Duke Blue Devils men’s basketball team.
