Neon has appointed 20-year Harrison and Star veteran Mardene Miller as EVP and managing director.

Miller joined the firm on February 1. She is leading the agency alongside creative lead and managing director Kevin McHale. Miller is reporting to Dana Maiman, FCB Health Network CEO and president.

Former EVP and managing director Mark Arnold exited the agency in January, according to an agency spokesperson.

“The work that Neon has produced for launches and world-class brands like Cosentyx and Invokana first opened my eyes to the agency,” Miller said, via email. “Now that I’m here, the depth of incredible brands and talent is astounding. I look forward to telling this story to the world and creating even more ‘never finished’ stories for existing and future clients.”

Miller previously spent more than two decades at Omnicom’s Harrison and Star, joining the agency in 1997 as an account supervisor. In 2012, she was named president of the firm. Harrison and Star has not named a replacement, according to a representative from the Omnicom Group firm.

In 2017, Neon’s estimated revenue was $34.5 million, an estimated 3% increase from the previous year. The agency works with clients including Genentech, Pfizer, and Novartis.

“Neon is made up of an incredible group of talented people doing really interesting creative work right now,” Miller said. “I am here to build on that momentum and grow the agency to its full potential.”
