Meet our Management Team

Because of our strong values and expert employees, we are fortunate that a great deal of our customer base is comprised of repeat customers and their word of mouth positive comments.

Shawn Walter

In February 2014 the business was sold to Shawn and Michelle Walter from Bill and Pat Kramer, who had owned the company since 2001. Shawn, the president of the company, has worked his way through every position within the company from general laborer, sales, sales manager, operations manager and general manager over the past nearly 20 years with our firm. Through his experiences in these positions, he has developed a unique perspective of the industry and how to best satisfy the needs of our customers. Shawn is a graduate from the Milwaukee School of Engineering (MSOE) with a degree in Mechanical Engineering-Technology.

Tom Morrow

With well over 20 years in the asphalt maintenance industry, Tom holds the position as Project Manager of our asphalt maintenance division. Tom spent many years working with the various crews (crack sealing, infrared repair and sealcoating) in the field where he learned and the best practices and methods towards a quality end product for our clients. Because of this background, Tom insists on providing very comprehensive quotes to his customers rather than simply give a low end and vague quote which will usually not be the best option for extending the life of the asphalt surface.

Ron Zirpel

Ron is a new arrival to Valley Sealcoat but brings with him over 20 years in the asphalt maintenance and paving industry. By working with his clients, Ron likes to assist them in their decision making by providing them with proposals that best fit their needs. With providing a quality project, extending the life of your asphalt surface becomes his priority.

Corey Dalimonte

In 2006 Corey joined our company as a field crew leader. Over the years he was a crew leader for all of the various tasks we perform which allowed him to fully understand the all of the aspects of our field work through hands-on experience. In 2012 Corey was promoted to his present position of Field Operations Manager and is responsible to expertly complete the work the sales team sells.

Karen Zempel

Karen is our office manager and in addition to answering the phone and responding to emails, types all of our customer quotes and enters orders for scheduling along with all the other tasks of running an office. Karen has been with us since 2006.


All of our crews are thoroughly trained and understand that only through providing our customers with excellent work will the company be able to continue to grow and maintain the quality reputation we have worked so hard to achieve. A special recognition to Mike V.W. and Donny for the many years of dedication (Mike-34, Donny-13) they have given to the company.
