Wholebake, one of the UK’s leading manufacturers of healthy snack bars, has appointed John McMullen as Chief Executive Officer, as the business enters its next phase of growth. John took up the role in September, succeeding Peter Unsworth, who stepped down as CEO and remains with Wholebake as a Non-Executive Director.
John brings extensive experience from across the food industry, having held senior technical, operational and general management roles at major blue-chip organisations including Heinz, Princes and Unilever. Over the past decade, he has led successful business turnarounds at Baxters Food Group and G’s Fresh, building a strong track record of guiding organisations through periods of growth and transformation.
I am delighted to have joined Wholebake at such a defining moment in its journey. The healthy snacking category continues to evolve at pace, with significant opportunities for growth across the UK, Europe and beyond. Wholebake has built a strong reputation for quality, innovation and partnership, and I am looking forward to working with the team to build on these strengths. Creating an environment where people feel trusted, empowered and proud of what they deliver will be central to how we achieve our ambitions.
