Copper Leaf Media and Dimension PR have merged to form Copper Leaf Media as a global entity. The merger combines Copper Leaf Media’s services in content marketing, graphics creation, PR, social media management, strategic branding, video and 2D/3D animation production, and web design with Dimension PR’s public relations and writing experience, along with ad campaign management. The combined agency will serve the AV, broadcast, lighting, pro audio and security industries.

Alicia Root joins the new global Copper Leaf Media business as part of the merger, having joined Dimension PR in a full-time account management role in 2025.
Founded by Roland Hemming and Kiera Leeming in 2016, Copper Leaf Media is based outside London and comprises 25 staff in the UK and several European countries. Hemming’s background is in audio and AV consulting and engineering, whilst Leeming brings media experience to the agency.
Copper Leaf Media’s merger with Dimension PR, founded by Brian Galante in 2010, brings the combined client roster to more than 40 companies. Galante has more than 25 years of industry public relations experience, preceded by several years as an editorial contributor and general assignment reporter with Radio World, TV Technology and NAB Daily News.
Galante takes on the role of president, Americas, and joins Hemming, Leeming and Marieke de Jonge on the board of directors. Galante will share business development responsibilities with Hemming and Leeming.
Brian Galante, president, Americas at Copper Leaf Media, said: “I was immediately impressed with the talent at Copper Leaf Media upon first partnering with them three years ago, as have my clients who have already leveraged their services across graphics, social media, video and more. This feels like home to me and I couldn’t be happy to be a part of the leadership team.”
Kiera Leeming, co-founder of Copper Leaf Media, added: “Having worked together informally and collaborated on several accounts for a period, this was the right time to enter into a formal relationship and come together to build for the future.”
Roland Hemming, co-founder of Copper Leaf Media, added: “We were introduced through a mutual friend at ISE 2023 who suggested we would be a natural fit, and it quickly became clear that she was right. Our unification establishes an official North American presence for Copper Leaf Media and benefits our client base worldwide through more resources, broader skillsets and a deeper talent pool.”
