Holstein Association USA Certified Judges Lists

Holstein Association USA Certified Judges Lists

Holstein Association USA is pleased to provide a list of certified judges that can be a resource for shows of all sizes around the country looking for a judge. Names and phone numbers are provided for everyone on the list, and those highlighted in blue have provided additional information including a photo, biography, and more about their judging experiences. Click on any highlighted name to link to additional information.

The list has two tiers  National and Approved. All National Holstein Shows will be required to select their judges from the National list. Associate judges for National Shows must be selected from either the National or Approved list. Nationally-sanctioned Junior Holstein Shows must select their judge from either the National or Approved list.

The 2024 Judges List has been revised to provide more clarity and transparency to members. The following changes have been made to the list:

red bullet To place on the National Judges List, applicants must have judged as a lead judge in a State Holstein or higher-level show within the last 10 years.

red bullet The list previously known as the Qualified List has been renamed to the Approved List.

red bullet The Approved List is made up of applicants who have participated in a Judges Conference within the last five years and received a satisfactory rating from the conference.

red bullet Also new in 2024, Judges must reapply every five years instead of every year.

With questions about the judges list, please contact Tim Ziemba at 315.730.3312, or via email
