Mars has appointed Myriah Gambrell-Glenn as general counsel for its global snacking business, effective December 1, 2025. Based in Chicago, Gambrell-Glenn will lead legal strategy, compliance, and risk management for Mars Snacking, which includes brands such as M&M’s and Snickers. 

Gambrell-Glenn will oversee legal operations across a business with more than 34,000 associates, a presence in over 150 countries, and more than 1,000 snacks sold every second.

Since joining Mars in 2010, Gambrell-Glenn has held senior legal roles across multiple segments and regions. Most recently, she served as general counsel for Mars Pet Nutrition, where she supported the integrations of Champion Petfoods and Pretty Litter, acquired in 2023 and 2021, respectively.

In her new role, Gambrell-Glenn will report to Andrew Clarke, president of Mars Snacking, with a dotted line to Stefanie Straub, vice president, general counsel and corporate secretary, Mars Inc.

“Myriah’s pedigree speaks for itself. She has built an outstanding track record at Mars, combining deep legal expertise with strategic insight. Just as importantly, she is a dedicated people leader who has a keen ability to spot potential and turn it into performance,” says Clarke. “This combination will be invaluable as we continue to navigate today’s complex legal and regulatory environment while expanding our global snacking footprint.”

Gambrell-Glenn will join both the Mars Snacking Leadership Team and the Mars Legal Leadership Team.

“I’m stepping into this role at a generational moment for our snacking business,” says Gambrell-Glenn. “It’s clear to me our legal team is uniquely positioned to be a strategic partner by enabling and accelerating our snacking growth agenda—creating the conditions for innovation to flourish at speed and scale while driving strong governance. I’m looking forward to partnering with such a talented team as we take on this opportunity together.”
