About Sandia Team

The husband-and-wife team of Karin Knolle and Jody Sullivan are the local owners of Mighty Dog Roofing of the Coastal Bend of Texas. They have one son, J. Michael, who joins them in the company, and two beautiful grandchildren.

Karin graduated from St. Edwards’s University in Austin while Jody graduated from The University of Texas at Austin. Karin began her career as a professional counselor in Austin and then returned to her family dairy business in Sandia where she worked for many years. She recently retired as a Jim Wells County Justice of the Peace, a position she held for more than 15 years.

Jody has spent his career as a landman in the oil and gas industry where he oversaw the acquisition and maintenance of oil and gas leases and producing properties for more than 37 years. Jody has personally overseen the acquisition of hundreds of thousands of acres of mineral leases over his career, primarily in South Texas.

Because of their respective careers, Karin and Jody understand the importance of transparency, honesty, communication, and understanding the customer’s needs and concerns. They leaped at the opportunity to join Mighty Dog Roofing after experiencing firsthand the quality, integrity, and vision of the company leaders, along with the entire team that makes it work.

They are excited to help modernize the roofing industry with new technology that provides the opportunity for superior customer service, knowledge, and success. They look forward to being able to assist their Coastal Bend neighbors in maintaining and improving their home by providing quality roofing, siding, windows, and gutters.

When they aren’t at work, they stay busy with a variety of interests and activities, including ranching, beekeeping, travel, the beach or lake, and trying great food.
