T&H Dairy is operated by Mike Halfman and his family near Fowler, Michigan. They milk 1,600 cows with about 4,400 acres of corn, alfalfa, wheat and soybeans.

In August 2025, they began roasting soybeans onsite, following almost a year of construction to build their own roasting and storage facility.
