Austin-based Callen has increased its ranks, thanks to a banner year.

The agency added five new clients and in the first quarter, reported a 12% uptick in revenue over 2024.

That success has resulted in the creation of a new Chief Opportunity Officer — Jess Monsey — and the hire of Mike Davidson as head of production. Monsey's remit is to identify growth opportunities for Callen's clients, such as clients, Disney, Disney+, Supercell, Long Drink, Olipop and Vera Bradley. Davidson, a Cannes Lions winner, leads creative production.

Both report to Craig Allen, Chief Creative Officer, and David Hughes, president.

Previously, Monsey was with The Paladins League, developing an organization focused on tabletop games like Dungeons & Dragons. Her agency roles include president-managing director at Wieden+Kennedy and 72andSunny. Her noted creative work includes Old Spice, which won the first One Show Penta Pencil for creative excellence and KFC.

Allen said Monsey's “leadership in identifying new opportunities and fostering strong client partnerships will prove invaluable.”

Also onboard is Davidson, a 20-year ad vet. He has worked on various brands, including Old Spice, KFC, Nike, Coca-Cola, The NBA, Frito Lay, and Mondelez. Most recently, he was executive vice president, managing director of brand production at PXP. His agency affiliations include and Media.Monks, Leo Burnett, and Wieden+Kennedy.

"Mike has a track record of coming to the table with ideas that break barriers, while moving the needle for major brands. He represents everything Callen stands for: hard work, bold creativity, and a deep commitment to our clients,” said Hughes.

Allen founded his agency in 2017. He worked at Wieden + Kennedy for nearly 10 years and credits the success of his eponymous shop to its collaborative culture, which formed a partnership last year with first-round NFL draft pick Bijan Robinson.
