About Jonas Builders

Jonas Builders is a family owned and operated business located in Milwaukee, Wisconsin.

In 1971 after years of owning and operating a construction firm, Gerald Jonas, and his son Mark, recognized the quality of buildings that were becoming available for purchase at that time due to the changing economy in Milwaukee.

Now after three decades of experience in the building/leasing business, let us help you with your space needs.
