Our Vision

What began in 1989 in a basement office has grown to become a recognized name in the earthwork field throughout Northeastern Wisconsin. Skill, integrity and hard work defines Ostrenga Excavating. The goal of every employee is to work hard and accomplish the task to the customer’s satisfaction.

The home office is located east of Green Bay off of Highway 29. The work range has reached as far north as Iron River, Michigan to as far south as Mequon, Wisconsin. Ostrenga has traveled at customers request as far west as Pueblo, Colorado.

Our workforce consists of Union members from The International Operating Engineers Union and the Wisconsin Laborers Union. The company has been a proud member of the Wisconsin AGC since 1999.

Ostrenga Excavating is a family owned construction business.
