Hearts & Science makes strategic senior appointments to support growth


Laura Collins has been appointed as Chief Digital & Data Officer – a newly created role at Hearts & Science, Omnicom Media Group’s full-service media agency.

This follows another recent senior appointment, Tom Cornell, who joined as Chief Investment Officer.

Garrett O’Reilly, UK CEO at Hearts & Science, said: “Hearts has delivered over £200 million in net new business billings growth over the past year, landing significant new accounts.

“We set out to disrupt the media agency ecosystem and this has clearly hit a chord with clients whose transformational ambitions match our own.

“The addition of Laura and Tom completes a world-class leadership team that will ensure we continue delivering on the promise of transformational growth for our clients.

“Laura has a proven track record in unlocking digital excellence in fast-growth agency environments, and there’s no-one in our industry better than Tom when it comes to responsible and transparent trading at scale.”

Laura Collins

Reporting to UK CEO Garrett O’Reilly, Collins will be responsible for the strategy and creation of new products and services, developed to reflect the future needs of Hearts’ clients.

Collins is also the UK lead for the OMG led Council for Accountability & Standards in Advertising (CASA).

CASA works with platforms including Meta, YouTube and TikTok to provide advertisers with additional control and transparency around ad placement. Collins was previously Managing Partner, Media Excellence at OMG UK.

Prior to moving to OMG in 2021, Collins was VP Head of Media at Merkle, and she was named as Campaign magazine Female Frontier Honouree for her work on diversity and inclusion.

“Hearts is on an impressive trajectory with clients that are actively looking to use digital innovation to stand out from the crowd” said Collins.

“This makes it a very exciting agency to be at. I’m looking forward to working with the executive team as we move into the next stage of our growth strategy.”

Tom Cornell

She joins recently appointed Chief Investment Officer Tom Cornell – another new role.

He brings nearly two decades’ experience to Hearts, most recently as Executive Director, Head of Agency partnerships at MG OMD, where he also led the Investment team for OmniGOV.

Cornell led the UK government’s media investment for 80 departments for eight years. His tenure covered some of the most challenging periods in living memory, taking in both Brexit and the pandemic, leading the team in responsibly navigating the Government’s largest ever media spend.

Cornell said: “I really enjoy working with clients and media partners who actively want to push boundaries at every stage of media activation, helping to drive innovation and increase standards across the industry.

“Hearts is the perfect fit for that, and I’m excited to have joined the team.”

The addition of Collins and Cornell expands the Hearts Executive leadership team to six people. They join UK CEO Garrett O’Reilly, Rachel Peace, who joined the agency as Managing Director last year, Chief Strategy Officer Simon Carr, and Amy Matthews, who was promoted to the newly created position – UK Chief Experience Officer in September 2022.
