Gillette Dairy, located in Rapid City, S.D. will close its doors June 1st. Owned by Kemps, a division of HP Hood, the plant employees over 60 people and has been in business for over 30 years.

Company officials said the plant will be shut down because it is not operating at full capacity, and sales in the region are highly competitive.

“This is all about marketplace dynamics and too much capacity for the existing sales,” said Jim Green, president of Kemps Foods.
