Our consultant team focuses on growing and managing our group of independent consultants. Senior team:


Buzz joined Eden McCallum in 2014 and is responsible for building our talent pool of consultants and shaping great teams.

Before she joined Eden McCallum, Buzz spent 10 years at McKinsey, initially as a business analyst before returning after an MBA at Columbia Business School and time at NTL Interactive. Her work focused on strategy and performance transformation across a range of industries, predominantly healthcare, public sector and latterly in agriculture. Buzz has also worked for Technoserve in Kenya, Wildlife Conservation Society in New York and most recently as a strategy advisor to Farm Africa.

Outside of work, Buzz loves being outdoors (ideally when the sun is shining!) and is a keen horse-rider, hiker and skier.

Catherine joined Eden McCallum’s consultant team in 2017 with a focus on shaping and building exceptional consultant teams.

Catherine’s background includes being part of Capgemini Consulting’s Business Model Transformation practice, where she focussed on operating model, transformation and change management projects, and worked across a number of industries including retail, financial services and utilities.

Catherine has spent two years with Teach First on their Leadership Development Programme following a degree in Natural Sciences from Durham University.

Outside of work Catherine is a keen horse rider and runner, and loves spending time in the countryside. She enjoys great food and wine and loves to travel to explore these. This year she travelled across Europe to run four half marathons and one full marathon (the latter included 23 wine stops!).

James joined Eden McCallum’s consultant team in 2015 with a focus on building great project teams.

Prior to this, James’ career began at JRBH Strategy & Management (since renamed ‘Board Intelligence’), a boutique strategy consultancy. There he worked as a consultant in industries including Media, Entertainment, and Pharma, later becoming the firm’s Operations Director. He went on to gain an MBA from London Business School.

James has an undergraduate degree in Biology from University College London.

Outside of work, James loves running alongside the Thames and cycling through the French countryside (refuelling on wine and cheese).

Franka joined Eden McCallum’s consultant team in 2019 as Head of the Benelux, overseeing all of our consultant activities in the Benelux.

Before she joined Eden McCallum, Franka spent almost 6 years at Simon-Kucher & Partners, a strategy consultancy focused on marketing, sales & pricing. There she was a Director and managed a range of projects across sectors such as Consumer Goods, Professional Services, Software, Healthcare and Construction.  She was also responsible for recruitment and people development for her local office in Amsterdam.

Franka has a Master’s degree in Human Resource Management from the University of Groningen.

Outside of work, Franka plays korfball (a typical Dutch sport) and loves skiing and exploring new cities and countries.

Sara joined Eden McCallum initially in the client team before moving across to the consultant team in 2015. Her current focus is on shaping and building great project teams.

She began her career in publishing, working with multiple magazine publications in the music industry following a degree in English Literature.

Outside of work, Sara loves trying to keep up with her energetic toddler and, if she has time, baking a cake or two to feed her secret (but unlikely) ambition to enter the Bake Off!

Helen joined Eden McCallum in 2011 and now oversees all of our consultant-focused activities.

Prior to joining Eden McCallum, Helen was part of Accenture’s strategy group and spent nine years working with Oil, Gas and Utility companies, particularly relating to Business Unit strategy and M&A for clients worldwide.

After Helen’s English Literature degree at Nottingham University, she joined the Civil Service focusing on issues related to the environment and transport.

Helen has recently ditched the gym in favour of outdoor workouts in the park and can often be spotted hanging off the monkey bars in all weathers.
