Dawson launched the agency in Ashington, Northumberland 62 years ago and was a key figure within the business right up to his passing, attending board meetings and weekly catch-ups.
Business development director David Chambers said Dawson “lived for” his agency, adding: “His ethos always remained the same.
“Tom started the business as a small family business, and this never changed throughout the years, as every member of the team was classed as family. He will be greatly missed by all who knew him.”
Chambers went on to describe Dawson as “a truly charismatic leader” who would leave behind “a great legacy”.
