About

Get all the Dirt!



  • 1970s

    Our Humble Beginnings

    In the late 1970s Tim started working with his dad and that’s when he fell in love with the grading business. Well known at the time for the quality of their work in custom house pads and agriculture work, Trinity Grading, Inc. quickly evolved to include more commercial, retail, industrial, and government work.

  • 1980s-1990s

    The Rental Business

    In the mid 80’s Tim bought his own blade and went into the rental business for himself. During the mid 90’s Tim moved to Washington State with his family for a year and worked for a large heavy commercial construction company putting in highways and working on airports.

  • 1990s-2000s

    Transition to Full Service

    Missing the California sun, Tim moved back to work with his dad and brother to expand operations. As the business climate evolved, Tim used his knowledge of the industry and his experience in estimating to form Trinity Grading, Inc.
