GRAND Nutrition was founded by Nutrition Professionals and Nutrition Coaches, Brian and Cari Treat. They have been in the Nutrition industry for over 11 years. During this time, Cari, Brian along with their team have helped hundreds of people throughout the country transform their health. They began attracting many clients and coaches who shared their vision of educating and inspiring others about nutrition. A few became many and a few years later, Brian, Cari and team had opened numerous Nutrition Bars throughout the United States. This inspired them to create the business, California Fitclubs, Inc. California Fitclubs are Nutrition Bars and Fitness Clubs that practice the 80% Nutrition, 20% Fitness throughout California. These establishments have helped thousands of people take on a Healthy, Active Lifestyle.

In 2017, Brian, Cari and a few of their teammates decided to expand their business to Idaho. TriLife Nutrition in Eagle opened in mid-2017 and many more Nutrition Bars are currently being built-out in the Boise area with plans to open in the Fall of 2019. ​Idaho Nutrition Bars are Idaho's source for custom meal plans, nutritional advice, NSF and Olympic Committee Certified supplementation, Fitness Competition Coaching, Professional Grade Body Scans, and more.

​In 2018, Brian and Cari moved to Fox Island, WA and opened a new business which would operate throughout the state of Washington, PNW Nutrition Concepts. Brian and Cari plan to have various Nutrition Bars operating throughout Washington, with their first location, GRAND Nutrition, Now Open in Gig Harbor.
