We are thrilled to announce the appointment of Mark Holtzen as Area Manager of the Twin Falls, ID office. Mark is replacing Rob Hegstrom, who retired at the end of May 2021.

After graduating from Utah State University in 1998 with a Master’s Degree in Civil/Environmental Engineering, Mark began working for Radian International on hazardous waste remediation sites at Hill Air Force Base. After one year at Radian, he began working at Amalgamated Sugar Company as their Environmental Engineer. In 2000, Mark was recruited by Bill Block and Tracy Ahrens to start working in the J-U-B Twin Falls office. Marked worked in the Twin Falls office until 2019 when he took a job as the City Engineer for the City of Twin Falls. After 2 years, he made the decision to come back to J-U-B to work as the Area Manager for the Twin Falls office. Mark is a licensed engineer in the State of Idaho with 23 years of experience in the planning, design, construction, funding, permitting, and management of water and wastewater systems.

Please join us in congratulating Mark and welcoming him back to the J-U-B family.
