Maritime Insurance, a HUB International Company

823 Niagara Avenue Sheboygan, WI 53081

Maritime Insurance Group, a HUB International Company, was founded on the belief that protecting your assets and developing a solid workforce are crucial to growing and maintaining a profitable business. Putting this philosophy to work enabled Maritime to grow into one of the largest locally-owned, independent insurance agencies in the state of Wisconsin.

Client-focused Philosophy

We pride ourselves on our client-focused philosophy: your interests are always our first priority. We know that each business and industry is unique, and a "one-size-fits-all" approach falls short. By evaluating the specific risks facing your business, we can identify weak points and provide smart solutions that work for you. 

Proven Network of Specialists

Our network of highly-qualified professionals is versed in virtually every personal and commercial insurance discipline. Our commitment to continuing education results in a level of expertise that most competitors cannot match. 

Creative Thinking

Your business is unique. That's why our expert staff assesses your needs and creates a tailor-made plan blending both traditional and non-traditional solutions.


Maritime was originally founded in 1937 by Harold and Bill Gottsacker as the Gottsacker Agency in Sheboygan, WI. As the surrounding area grew, the Gottsacker Agency evolved into one of the largest independently-owned agencies in Wisconsin with expertise in Commercial Property and Casualty, Employee Benefits, and Personal Insurance. In early 2013, Maritime was acquired by HUB International, becoming a part of HUB Midwest.

From our locations in Sheboygan, Manitowoc and Plymouth, we have continued this tradition and developed divisions that specialize in specific risk areas from the most basic individual customer needs, to the most sophisticated corporate requirements. Our goal is to give you the same prompt, cost-effective, and high-quality service we have been providing since 1937.
