The 2025 Women Leaders in Consulting: Rhiannon Thomas

Rhiannon was born in Bedford near London, but her parents moved to France when she was three months old. She was educated in the French schooling system until the age of 18 and then moved to the UK to study Economics & International Relations at Warwick University, followed by an MPhil in Economics at Cambridge University. She started her career at Interbrand working in the brand valuation team producing the famous Best Global Brands League Table. In 2006, she moved to Mars & Co, a boutique consultancy focused on consumer goods and started working with some of the leading global consumer players. In 2013, she took a career break and volunteered in Zimbabwe for Technoserve (an NGO focused on business solutions for poverty). In 2014, Rhiannon joined Kearney’s London office in the consumer goods and retail practice and returned to working for large consumer players across the globe. She became an equity partner in January 2020 and the Global practice lead for Consumer Goods and Retail and Senior Partner in 2023. Rhiannon loves the outdoors. Whatever the climate, wherever she may be, she likes nothing more than going to bed exhausted from the effort of being out in the elements.
