Lime Media Appoints New Leadership to Support Next Phase of Growth

Rockwall, Texas — January 16 — Lime Media announced key leadership appointments to support the company’s continued growth and operational scale. Bart McCollum, formerly Integrator of Lime Media, has been appointed President, and Spencer Rose has joined the leadership team as Chief People Officer and Head of Teams & Talent. Founder and CEO Heath Hill has led Lime Media through extraordinary growth since its founding in 2005 and will continue to guide the company with a focus on vision, culture, and strategic assets.

In his role as President, McCollum will focus on building the operating system and infrastructure that allow Lime Media to scale with discipline and confidence. As Integrator, McCollum played a critical role in strengthening execution, aligning teams, and operationalizing strategy across the organization.

“Bart has been instrumental in building the foundation that supports how we operate today,” said Heath Hill, Founder and CEO of Lime Media. “As President, he will continue to strengthen our infrastructure and execution model so we can scale intentionally without losing what makes Lime unique.”

Spencer Rose serves as Lime Media’s Chief People Officer and Head of Teams & Talent, stewarding a people-focused culture grounded in the company’s core values. Rose has over 25 years of HR experience, including 20 years in the marketing industry, with a background in senior HR leadership roles.

Over the past several years, Lime Media has built something different—not just the largest collection of mobile experiential and LED mobile billboard assets, but a nationwide physical platform designed to execute quickly and deliver measurable, data-driven outcomes for brands.

“We sit at the intersection of experiential marketing, mobile digital out-of-home, data, and execution,” said McCollum. “We’re investing heavily in the systems that allow those pieces to work together at scale, giving our clients both speed and accountability in how campaigns are delivered.”

These leadership appointments reflect Lime Media’s commitment to disciplined growth, operational excellence, and continued innovation across experiential and digital out-of-home marketing.
