S.T. Concrete inc Claim business
About
I started in the construction field in 1987 and registered with the City of San Jose in 2000. It began as a side job to make ends meet for my family, loved the field and decided to work at it full time. I've done thousands of projects and each project is unique to me. - Serafin TrejoServices Offered
