Sinacola is a 100% employee-owned company that specializes in heavy civil construction such as building roads and bridges, including excavation of public and private developments, underground utilities, structures. Sinacola is headquartered in Frisco, Texas. The history of Sinacola is one based on family values, safe work, and forward-thinking that began over 50 years ago. Founded in 1966 by Mario Sinacola, the company known as Mario Sinacola Excavating, Inc., employed fewer than 15 workers and performed small utility installations around the Detroit metro area. In 1979 the crippling downturn of the Michigan economy prompted Mario Sinacola and his sons to look for work elsewhere. Mario’s sons then relocated the company, formerly known as Mario Sinacola & Sons Excavating, Inc., to the Dallas-Fort Worth area.Sinacola became employee-owned in 2017 when it implemented an ESOP. This provides all employees with a stake in the future growth of the business and becoming indirect owners of Sinacola.
