est. 1946

1946 was the beginning of a small family of companies that are known today as

Sebastian. The first of these companies was Kerman Telephone Co., purchased by Bill and Katey Sebastian on June 20, 1946. Their reason for purchasing the company, in Bill’s own words, was simple:

"My wife Katey and I scraped up our courage and our last dollar, and bought an opportunity in the form of Kerman Telephone Co."

Today, that courage and spirit of opportunity – what we call the Spirit of 46 – continues to flourish and reflects our company’s values, purpose, and vision for the future.
