Within a fortnight of winning the by-election Mr Granville finished his job as the breakfast host at MoreFM after five years, and he and his good mate Jimmy Elliott took over as new owners of Take It Easy Tours.
"To say it's been a challenging two years for me is an understatement. Everything happened at once."
He said he had enjoyed his time on council, describing it as both interesting and frustrating at the same time.
"It would be fair to say it was a much different environment than what I was used to."
While the business remains his focus Mr Granville has not discounted getting involved in local body politics a few years down the track.
"I'm only 33 and in another 10 years things may be different with our business so I might have more time," he said.
