We would like to thank Grey Lemon for their expert guidance in clarifying the great things about our business and helping us to build a strategy for the future that we are proud of. We now have a clear vision of where we are going and how we are going to get there, supported by values that reflect the quality of our team and that our clients wish to see. We have loved working with the Grey Lemon team and look forward to continuing our relationship with them.

Grey Lemon provided strong challenge and support around the nature of the change we want to create, the scale of our ambition and what success would look like.  Getting our ‘pole star’ right has been fundamental to the development of our strategic objectives and the strategy underpinning their achievement.
The time Victoria and Rhonda spent understanding our charity, our mission and impact to date was so important in ensuring our time was well spent. They have been utterly professional throughout this process and easy to work with.

We are a very different organisation today than we were 18 months ago, and Grey Lemon has been a major part of this.  They encouraged us to take a critical look at our business strategy, structure and market approach, resulting in a fantastic shift in our own mindset; a shift that is already paying dividends.  Such change doesn’t happen on its own. Thank you, Victoria and Rhonda.

As part of this plan, they defined a series of targeted, creative campaigns that spoke directly to the client groups I wanted to grow – and its already translated into genuine results.

Artemis Interiors instructed Grey Lemon to help with the launch of a new service, Office Re-engineering. From the outset, both Rhonda and Victoria were incredibly knowledgeable and professional. Grey Lemon really helped elevate our offering all the way through; from positioning recommendations, key messaging, content strategy to the planning and implementation of the launch. We’re pleased to say that our new service has been very well received!

Having known and worked with Rhonda for many years, when I knew that she and Victoria were teaming up to create Grey Lemon, I had no hesitation in immediately picking up the phone. Our new business consultancy venture needed a dynamic skill set I knew Grey Lemon had! True to my expectations, they delivered fantastically.
Russell Middleton, Director

Spinnaker Consulting Group

As a global business, we have grown consistently in the last 8 years, but we found performance across regions was patchy. Grey Lemon was able to quickly identify where the main source of the problem was and gave us a set of clear actions to address it. We found Rhonda and Victoria to be honest, informed, and importantly really good to work with.

Grey Lemon brought the personable, no nonsense approach we needed to help us clarify our purpose for the People’s Pavilion. They worked WITH us to establish a clear vision for what we were trying to achieve and their industry experience, knowledge and understanding of social, sustainable and environmental impact shone through from day one. I highly recommend this dynamic duo.

Beyond the Box Consultants

Originally in the role of Director of Linesight, responsible for the establishment of the UK office, Rhonda was promoted to Chief Marketing Officer leading our Global Comms Team with responsibility for the marketing and development of the Linesight business around the world. Rhonda brought vast experience and an extensive network to our business, She brings an energy and enthusiasm to her work and has particularly strong skills in building external relationships with key stakeholders.


Victoria’s contribution to developing and applying market intelligence in conjunction with strategic Business Development has directly built a stronger presence for Hassell across EMEA. This work has increased understanding of and demand for our capability, which has been a result of her 100% commitment to helping us achieve our objectives. She has helped us achieve a range of notable successes with clients across the sectors we work in, too numerous to mention individually. This significant contribution will remain relevant and invaluable for us in the future.


After working for major developers for more than 25 years, my business partner and I decided to set up on our own. The insight Rhonda and Victoria gave us in the early stages of business establishment and growth was invaluable. They asked the hard questions and helped us filter through all the ideas to shape a structure and positioning for our business that has caught people’s attention and translated directly into profitable work.

SBI is on track to be in the best shape it has ever been thanks to the insight and guidance of Grey Lemon. Working with them has helped us crystallise our vision, streamline our business model and work more efficiently for the benefit of both ourselves and our clients. The Grey Lemon process was in-depth, challenging and enlightening. They were respectful of our 25-year history and pushed us to explore an ambitious vision for our future; with that has come a genuine sense of excitement for how we move into a new era for SBI.
Russell Mumford, Director

Sapphire Business Interiors

We chose to work closely with Victoria and Rhonda at Grey Lemon due to their reputation in tackling the grey areas in strategy and implementation, something we knew we needed to address if we are to increase our focus and impact.
The style of questioning and challenge made us work really hard to think through how our intended actions might pan out, and about the significance of planning with precision and intent. Consideration of measures and implementation as we progress our vision, mission and objectives meant that we were able to think clearly from the outset, and now look forward to putting this into action.
