Dark Horse Comics recently unveiled a new leadership structure for the company, offering insight into the future of this foundational comics publisher. Dark Horse will now be led by three department heads: Tim Wiesch, Head of Publishing and Business Development, Vanessa Todd-Holmes, Head of Publishing Operations, and Melissa Teeman, Head of Finance and Administration. Each of these three leaders represents a move towards collaborative operation and reliance on the expertise of veteran Dark Horse staff to grow the company. 

In addition to the new leadership, Dark Horse has promoted several employees internally to senior roles including: Mark Bernardi, who has been promoted to Vice President of Publishing Sales, Daniel Chabon, who has been elevated to Executive Editor, and Samantha Garcia who has been promoted to Director of Marketing. 

Dark Horse also welcomes publishing industry veteran Kevin Callahan who has signed on as the new Vice President of Marketing.

Callahan’s role as Vice President of Marketing, in addition to Bernardi’s promotion to Vice President of Publishing Sales, reinforces a move towards better focus in the Marketing, Advertising, and Sales strategies within Dark Horse Media that began with the hiring of Stuart Schreck as Director of Sales in late 2025. The reinforcement of support for direct market business, in addition to large-scale, global retailers and the impact they have on publishing, products, and entertainment, is a key focus for Dark Horse moving forward, reflected in the internal promotions and acquisition of key industry talent.

After starting his career at Dark Horse Comics in sales and international licensing, Wiesch also spent time in licensing at Mondo and the Alamo Draft House Cinemas. In addition to the comics creators and industry relationships he’s developed over the years, he’s also been a passionate advocate for creators rights and expanding our footprint to include tabletop gaming, tie-ins with nostalgic brands, musicians and more. His return to Dark Horse and promotion to Head of Publishing demonstrate his passion for the longevity and excitement for everything we do.
