Walrus Appoints Agency Veteran Mallory Diamond as Head of Development

Mallory Diamond has been brought on as Walrus’s head of development, a new role at the New York-based independent full-service advertising and media agency. She joins the shop from Rochester-based Partners + Napier after 11 years working across new business, marketing and comms, most recently as its director of agency growth.

Mallory’s appointment comes during a period of sustained growth for Walrus. This past year alone the agency landed clients including Jet Edge, Topic streaming service, Northwest Arkansas Council and AuthO while doubling the size of its media department.

As head of development, Mallory will lead all new business efforts and work alongside co-founder and CEO, Frances Webster, and co-Founder and CCO, Deacon Webster. In addition to vetting and pursuing new client relationships, Mallory will also champion Walrus’s fast-growing media business. Clients Lowes Foods, Quality Branded restaurants and Northwest Arkansas Council have already consolidated media and creative with Walrus. 

“Walrus’s demonstrated ability to win larger, more diverse pieces of retainer business can be directly attributed to investments we’ve made in senior media, design, strategy, and production talent over the past several years, and our independence has allowed us to make these types of bets that take time to pay off,” noted Walrus CEO, Frances L. Webster. “Investing in a new business role is a critical component to our expansion, and Mallory is at the top of her game and the perfect fit for this role.”

In her previous role, Mallory helped secure national clients such as NYU Langone Health, Rip Van, CoreLife Eatery, Real Good Fish, and most recently, leading telehealth provider MDLIVE.

She led, managed or contributed to numerous pitch engagements in varying new business roles over the past 11 years, spanning food and beverage, healthcare, restaurant, financial services and travel categories, all of which are areas of strength for Walrus given their work with brands like PayPal, General Mills, Slow Mag, Smith & Wollensky and The Walton Family Foundation.

“I’ve long admired Walrus for their fearless creativity and clarity of vision,” said Mallory. “Frances, Deacon, and the broader team are famous for ‘I wish I thought of that’ ideas, and I couldn’t pass up the opportunity to be a part of the magic. I’m proud to join the agency in this role and I look forward to introducing more of the world to Walrus.”
