Post Holdings, the US owner of Weetabix, has appointed a new Managing Director for the breakfast cereal business.

Weetabix’s current MD, Sally Abbott, is moving to the role of Strategic Advisor from 1 October after nine years leading the unit. She will be succeeded by Colm O’Dwyer, who is currently the brand’s Commercial Director.
To support the transition, both will work together until Abbott’s planned retirement on 31 March 2025.
O’Dwyer joined Weetabix in 2016 from Coca-Cola Enterprises in the UK, eventually becoming General Manager of the Weetabix On-The-Go business. In 2018, he became Commercial Director and then added responsibility for Weetabix’s international business in 2022.
The group highlighted that O’Dwyer had transformed Weetabix’s pricing and promotion strategy, evolved the company’s approach to customer relationships and reinvigorated its international strategy.
“Sally has been an exceptional leader, helping to successfully integrate Weetabix into Post and building on the success of this iconic company,” said Post’s President and Chief Executive, Robert Vitale.
“We wish Sally the best as she approaches her next chapter and congratulate Colm on his new role. Colm’s experience across innovation, brand management, revenue growth and customer relationships makes him exceptionally qualified to lead Weetabix.”
The company stated that it is currently evaluating candidates to fill the Commercial Director role vacated by O’Dwyer’s promotion.
