Agency Information

Three Rivers Agency, Inc., was established January 1, 1989, when McCarroll-Diener Agency merged with Triangle Bar Agency.

The following is a brief history of the Agency's history.

McCARROLL-DIENER INSURANCE AGENCY
In the fall of 1919, Ben F. McCarroll purchased a number of small insurance agencies in Payette, New Plymouth, and Fruitland and formed the B.F. McCarroll Insurance Agency. In October of 1923, H.K. Dent, founder of a company that later became known as Safeco Insurance Companies, convinced Mr. McCarroll to represent what was then called General of America Insurance Company. Other companies that Mr. McCaroll represented at that time, like the Hartford and Reliance, canceled their agency contracts when they learned of the new association with General.

Mr. McCarroll operated the agency alone until September of 1945. It was then that his son John R. (Bob) McCarroll, joined the firm. A few years later in 1949 Mr. McCarroll, the founder of the agency passed away. Then in 1955 another son by the name of Mark McCarroll joined the agency. On July 1, 1958 Mark purchased the interest of Bob McCarroll and became the sole owner of the agency.

Mark continued to operate the agency alone until June 1, 1980 when Hugh Diener, a long time resident of Payette and a former officer with the Idaho First national Bank (currently US Bank) joined the firm. At that time the agency changed its name to McCarroll-Diener Agency. In January of 1983 they purchased the Gist & Powell Agencies of Fruitland and New Plymouth, Idaho and then to complete their agency they also added the Mountain West Agency of Fruitland in November of 1985.

TRIANGLE BAR INSURANCE AGENCY
The Triangle Bar Agency originated in 1908 as the Fitch Realty Company which was founded by Mr. Bert R. Fitch. That company originally sold real estate only, later they added the selling of insurance as a side business. Mr. Fitch’s original insurance company appointment was with The American Insurance Company of Newark, New Jersey. Mr. Fitch closed his agency prior to the start of World War I to become a dry land farmer in the Dry Buck area, which is west of Banks, Idaho.

In 1928, Neil R. Fitch, son of B.R. Fitch, joined the Fitch Realty Company. Fitch at a later date discontinued the real estate business and focused solely on the insurance and bond side of the business.

In 1951, Jay D. Fitch, son of Neil, joined the Fitch Agency. Jay later purchased his father’s interest in the agency and subsequently renamed it the Jay D. Fitch Agency Insurance, Inc.

On November 1, 1970 Mr. Gene m. Gray after returning from serving his country as a Captain in the United State Marine Corps in the Republic of Vietnam, purchased the Jay D. Fitch Agency. In 1971 renamed it the Triangle Bar Agency.

MIDDLETON INSURANCE AGENCY
Mr. David Gray started working with TRA in October of 1994 following his graduation from Albertson College. Initially the idea was to continue to learn the business under the tutelage of Gene Gray and Hugh Diener and eventually run the corporation upon their retirement. However, a few months later the opportunity arose to buy “a small book of business” from a captive only company and locate it in the community of Middleton, Idaho. Mr. Gray continued a brokering association with TRA but ran the business independently for the following 7 years.

Middleton Insurance officially merged with TRA in the summer of 2001 with the hiring of Michael S. Holcomb. Mike, also a graduate from Albertson College and Payette High School had been working in the finance sector prior to his employment with TRA. His role was to manage and grow the Middleton office. David, thus, moved to the Payette office to familiarize himself with the day-to-day operations of the corporation.

AGENCY WEST INSURANCE, INC.
July 1, 2004, Three Rivers Agency expanded with the purchase of Agency West Insurance. Agency West at the time was owned by Jack and Pamela Barnes and had history to the 1940’s. Originally opened in Caldwell under the name of Glaiser-Harris, the name was altered a few times over the years before Mr. Barnes and his partner Donna Dillion incorporated and changed the name to Agency West.

WEAVER-VAN DEUSEN INSURANCE AGENCY
Bradley Sheppard started the agency in Boise in 1913 and managed the business until the 1930's when his widow sold the agency to Walt Hayes and Lew Raeder. The name changed to Hayes-Raeder and operated with the two owners until 1946 when John VanDeusen joined the agency as the third partner. The new entity continued until the retirement of Walt Hayes in the 1960's. Raeder-VanDeusen continued their partnership into the 70's until the retirement of Lew Raeder left the business solely to John VanDeusen. Jack Weaver who, as a child mowed the lawn of one of the early principles joined the agency on November 17, 1975. His work ethic and business savvy quickly transformed the agency into one of Boise's finest. The name changed to Weaver-VanDeusen in 1979 and he finally bought John VanDeusen in 1983. Effective January 1, 2007, Mr. Weaver has decided to become more dedicated to his Yellowpine property and will turn over the agency to Three Rivers Agency, Inc.
