The Dyes sorely missed out on the Conference X title in the first division of the East of Scotland Football League on Saturday, despite beating bottom-placed Pumpherston 7-0.
Whitburn relegated her to first place with a spectacular 12-0 win over Fauldhouse to overtake her on the final day.
“That’s the disappointing thing for us today,” he said after the game. “At the end of the day, Whitburn scored more goals than us and because of that they deserved to go on and win the league.
“I heard they played most of their game against ten men but to be honest none of that matters, it’s settled now.
“We scored seven goals but we could have scored seven more, it just didn’t happen for us.
“I’m just happy that the club is rising, that’s the most important thing.
“Obviously it would have been great to win the title, but it was just a bonus overall.
“The end of the season was brilliant and it was really exciting to be a part of it was brilliant and the players will have learned so much from it.
“I couldn’t ask for more from them what they’ve given me this season and the past few weeks.”
The ex-Shire boss, who had an extensive playing career with the likes of Kilmarnock and Queen of the South, added that guiding the side to promotion has transcended any moments he’s had as a player.
He said: “I’ve won a couple of promotions as a player but never as a manager so it’s a great day for me, really, this is one of the best days I’ve had in football.
“Even at this level of football, there is something special about going up a league in front of a crowd as big as this, full of people who really care about the club.
“I’m very happy for our director of football Steven Allison and this day is for him. He had a dream to create a successful soccer team and today is the beginning of that journey.
“In the first year of a club at this level we have to be proud of what we have achieved and that goes for everyone from our side to the brilliant youth system.
“I was stunned to see the turnout today and it shows the appeal of the club as we continue to do well.
“We have our own city to build on and obviously the long-term goal is to one day be a Grangemouth-based team.
“It’s the biggest win I’ve ever had in football. I’ve won leagues as a player but this is the best day of all for me.”
