– Company Celebrates Milestone Achievements and Continued Growth While Saluting Retiring CEO Ian Davis –

OAKDALE, MN (June 16, 2025) — QualiTru Sampling Systems® (formerly known as QMI), leaders in the science of aseptic and representative sampling equipment for the liquid food and dairy industries, announced today that David Roesser, Ph.D. is joining the company as its new Chief Executive Officer. A specialty chemical, agricultural and food processing industry veteran with over three decades of experience in commercializing new technologies across a range of industrial markets, Dr. Roesser is assuming the helm from former CEO Ian Davis, who is retiring. 

“We are excited to have Dave joining QualiTru and thank Ian Davis for his many contributions to our company. Under Ian’s leadership, QualiTru exceeded its growth targets and reached several significant milestones. These included launching the Company’s new TruStreamTM Drum Port for non-dairy liquid foods markets, and bolstering our manufacturing and internal assembly operations,” said Robin Schroeder, QualiTru Sampling Systems’ Board Chair. 

“I am very excited to be joining the QualiTru team,” Dr. Roesser said. “For over 40 years, the Company has been the leader in liquid sampling technologies, with proven, cost-effective solutions that help the commercial dairy and liquid food industries easily perform reliable aseptic, representative, sanitary, and hygienic sampling. “However,” he continued, “Our work is not yet done: despite rigorous pasteurization and sanitation standards, microbial outbreaks, cross-contamination and in-line issues such as biofilm formation can still occur in commercial dairy and liquid food processing environments. Our customers are continually challenged to mitigate the potential risk of foodborne illnesses, and QualiTru is uniquely positioned to help them address their critical process-related needs, whether they require enhanced microbial detection, greater contamination control, or increased adherence to rigorous sanitation and HACCP protocols. I look forward to working with our team and industry partners as together, we extend QualiTru’s legacy of pioneering innovative liquid sampling solutions that serve as a critical safety and quality practice for these industries.”
