Remembering Grey Culberson

It is with heavy hearts that we announce that Grey Culberson, co-founder of Pinnacle Sales Group, passed away in August.

After serving in the Army Intelligence Service, Grey joined Everpure in the 1950s where he worked in various sales and marketing roles. In the late 1970s, Grey was tasked with developing a line of Everpure products for the domestic residential market. 

In 1980, he and his wife, Joanne, established a sales agency, Water International, which later became known as Pinnacle Sales Group.  Everpure was the first product line for his new company, which our partners at Pinnacle continue to market to this day. 

A graduate of Wheaton College, Grey also studied marketing at Northwestern University.  He loved everything about business, but his passion was always marketing.

Grey is survived by his wife Joanne, his son Kent, and two daughters Chris and Kim. He has three grandchildren, and two great grandchildren.  A lifelong Christian, he served as an elder and teacher in the church for most of his adult life.

It is because of Grey's dedication to carrying out CB Oliver's vision for luxury consumer water filtration that Everpure grew into the company we are today.
