For over 40 years, Donkersloot & Sons Marine Development Co. has been the "go to" organization for complex construction projects in a marine environment both as a general contractor and a valued subcontractor.

Started in the 1960's by Arie Donkersloot Sr who brought his Dutch experience on harsh marine environments with him when he emigrated to the U.S. from his native Holland in the 1950's. The company began with Arie's technical training and practical experience in mechanical systems and construction techniques. Equally important, he brought with him his positive "can do" attitude combined with his unique creative abilities.

His sons joined their father in the 1970's to form the family construction company. In 1989, the company incorporated in Michigan as Donkersloot & Sons Marine Development Co. with Arie Donkersloot Jr being named President and Ronald Donkersloot Vice President. Together the second and third generation continue the company's tradition of innovation and quality workmanship on all their projects.

Donkersloot & Sons have completed projects both on and off shore in at least five states (MI, IN, WI, IL, and FL) and is a listed marine contractor with the US Army Corps of Engineers. This extensive work utilizes many innovative designs and construction concepts and techniques.

The company continues to expand their capabilities in the marine construction industry. In 1989 they added a custom built, innovative 120 foot work vessel, the M/V Miss Jamie Lynn, to support their activities

Donkersloot & Sons has received several awards in recognition of their outstanding work product (see examples on the 'reference projects' page). A parital list of project references demonstrates the diverse capabilities of the company.

In 2009, sons Arie Donkersloot Jr and Ronald Donkersloot bought out Arie Donkersloot Sr's interest shares of Donkersloot & Sons Marine Development CO.
