Marty Costa


Marty has been employed in the construction industry since 1982. He loves that his work is in beautiful settings, close to home and working with great people. As a superintendent with JMA since 2003, he appreciates the company’s commitment to excellence, the challenges that come with every project and learning something new nearly every day. His superior organization skills and sharp focus on details allow him to excel at pre-planning, identifying potential problems early in a project, before they become issues. His talents at diplomacy and his genuine team orientation make him a valuable asset on any construction project.

Outside of work, Marty likes motorcycles, scuba diving and doing projects at home. Hidden talents include gardening and amateur beekeeping.

Favorite JMA projects:

  • Solage Resort, high-end resort with multiple structures
  • Williams Selyem Winery, production facility & administration building
  • East Sonoma County Estate, custom home with European touches
