Circle41 Club

Circle41 is an exclusive community of our Members who are seeking life's most unique experiences and fine caviar.

The origin of Circle41 dates back to the 1800s when our founder, Michael Passmore's great grandfather, homesteaded land in Oklahoma. Later, his great grandfather's son, Clarence Fowler, would establish his infamous cattle brand, "41". Over the years, under Clarence's direction, the family's ranch was involved in the earliest days of aquaculture in Oklahoma, supporting the development of conservation and becoming a source of incredible fish.

Nearly a century later, his grandson Michael continues this family tradition by farm-raising freshwater fish in Northern California. To commemorate his grandfather's brand and to recognize a growing circle of family, Michael established his own brand, "Circle 41".

In honor of that heritage, the Circle41 Club was established and is reserved exclusively for our Members.
