About Us

Granby Telephone Company has been in existence for over 114 years and has been owned and managed by the Stouffer family since 1930. The business was started by individual business owners in Neosho and Granby in 1904 and bought by L. Q. Adamson in 1929. In 1930, Harold Stouffer came to assist Adamson in his business endeavors, and soon became the sole owner after Adamson’s death. The company was then owned by Harold’s son, Dale Stouffer, and his wife, Shirley Stouffer, for 30 years. Their son, Jon Stouffer, then became the President in 1987 and created GTC Broadband in 2010 as the main Internet company. In the time Jon has been the CEO, he has established state-of-the-art Fiber to the Home (FTTH) for all of Diamond and most of the Granby customers, and this project is continuing to grow. Jon’s daughter, Savannah Stouffer, currently works at the company. She plans to one day follow in the footsteps of her family members by becoming the fourth-generation owner of the company.

Today, GTC Broadband offers state-of-the-art Fiber-Optic Internet connection at a Gigabit. This type of Internet connection is the same as Google Fiber, but is offered with hometown customer service to residents of Diamond and Granby, Missouri.

However, since it is technology, it is impossible for it to never go down or have some issue arise. During the past 10 years, we have been investing in a completely underground Fiber to the Home network to serve all our customers in Granby and Diamond.
