Global Head of Leadership & Talent

This was a deceptively simple and overwhelmingly effective course. Really saw lightbulbs going off all over the place.

Katie was excellent as usual. Her insight and reassurances elevated the course from useful to genuinely enlightening. Thanks for your passion and dedication!

Gareth was incredibly engaging and knowledgeable, with a deft touch in giving feedback and marshalling the group. 

As always, Gina delivered with knowledge, compassion, thoughtfulness, insight, humour and familiarity with our organisation. Great job!

We did it on Zoom and I think it made the experience SO much better!

Katie coached us through the process in the same fantastic way she always does. Being on Zoom was highly effective.

Thank you - it had a huge impact on my approach to work and life.

The best training workshop I have ever been on. So interesting and insightful.

Really good course which totally exceeded my expectations. Has helped me solidify my desire to become a leader and I’m looking forward to moving my development plan towards this goal.

Sian really demonstrated mastery of the subject matter and tailored the course to what appeared quite an experienced group.

I have been on similar training courses in the past but this had the best content by far. No death by PowerPoint and all exercises were clearly outlined and easy to understand. Katie was a fantastic facilitator. So helpful and full of information and great examples of previous issues and knowledge.

Kate is a real gem and I look forward to working with her again and to recommending her to others within my network.

Head of Sales Channels

Katie was my inspiration for becoming a coach myself and also help others achieve great results.

UK Sales Manager

Really positive experience through which there was a lot of team bonding. Gareth had a very good way of making everyone feel at ease and we all went away feeling like we'd genuinely learned something as a team.

The trainer was extremely knowledgeable and personable and demonstrated several practical techniques covered to great effect. Her experience and confidence were a huge asset.

Katie is super-inspiring, challenging and a fantastic facilitator. Thank you!

Such an intimate setting with multiple different people with real scenarios made it very applicable and easy to grasp.

Excellent investment in ourselves as a team - very insightful and well led.
