Welcome to Mullen's Dairy
From our family - To yours.
Our roots run deep in Wisconsin.
Founded by dairy farmer Frank Mullen Sr. and his sons, Frank Jr. (Moon), Weber and Gerry, Mullens began as a brick and mortar operation where the Mullen’s bottled their milk and sold a variety of dairy products including milk, butter and cream. By the ’40s, the three brothers added ice cream production to the mix.
Mullen’s is known for its creamy and delicious ice cream. It sells small batch homemade ice cream in retail outlets throughout Wisconsin and is more than happy to scoop it up for you in the shops. Today it’s owned by three brothers from Oconomowoc: Josh, Matt, and Adam Keepman

A tradition in the making.
In 2016, three brothers made the fateful decision to keep the legacy of an 85-year-old business alive. But the Keepmans are just one of many families with memories tied to Mullen’s Dairy Bar, the iconic ice cream shop and diner that has roots dating back to 1932.
