We are delighted to announce the appointment of Dan Ridler as Chief Customer Officer, a newly created executive leadership role designed to strengthen the connection between its market strategy, client needs and successful delivery.

The appointment supports Sullivan & Stanley’s long-term growth strategy as it strengthens its client leadership capability and continues to invest in delivering meaningful outcomes for clients.

Dan will oversee Sullivan & Stanley’s customer strategy from initial market engagement through to handover to delivery, ensuring long-term client value. He will bring together marketing, partnerships, client leadership and consulting propositions, ensuring our services are aligned with the challenges clients are facing and can be delivered effectively as the business scales.

As part of the new role, Dan will also be accountable for revenue and client profit and loss, with a focus on creating a more consistent approach to growth and ensuring clients experience a seamless journey from their first interaction with Sullivan & Stanley through to measurable business outcomes.

Dan joins Sullivan & Stanley with more than 20 years of consulting experience across financial services. Most recently, he was Managing Director at Accenture and prior to this, Managing Director at BCS Consulting. His experience across both specialist consultancies and global firms gives him a strong perspective on how to combine the agility and close client relationships of a challenger consultancy with the discipline and scale of a larger organisation.

Andy Haley, Chief Executive Officer at Sullivan & Stanley, said: “Dan joins Sullivan & Stanley at an exciting point in our growth. He has built an outstanding reputation for helping organisations tackle complex transformation challenges while developing trusted relationships with senior leaders. His experience of scaling high-performing consulting businesses, combined with his unwavering focus on delivering measurable outcomes for clients, makes him a natural fit for our growing team. As we continue investing in our client experience and expanding our capabilities, Dan will play a pivotal role in helping our clients realise greater value from their transformation ambitions.”

Dan Ridler, Chief Customer Officer at Sullivan & Stanley added: “What attracted me to Sullivan & Stanley was its ambition to do consulting differently. The firm has already built strong momentum, and I’m excited to help build on those foundations. Having worked across both specialist consultancies and global firms, I’m looking forward to bringing those experiences together to help our clients navigate increasingly complex transformation challenges and support the next stage of the firm’s growth.”
