DHIA Technicians

DHIA technicians are the foundation of our entire DHIA program. When the DHIA tech does a good job, the entire organization shines. Without their hard work, willingness to work long, early and late hours and their dedication, our program would falter.

We have DHIA professional techs that are eager to service your herd. Currently we have 13 techs based in Missouri, 1 tech based in Arkansas and Oklahoma, 5 techs working in Kentucky, 1 tech in Nebraska, 1 tech in Louisiana and 2 techs working in Mississippi.
