DMM Training & Development Reviews

I have attended a number of management courses over the years, but Diane delivers leadership development in a way that is both engaging and highly practical. Throughout the programme, there was a strong emphasis on meaningful self-reflection. Not only individually, but as a group. Diane created a supportive environment that encouraged honest discussion and personal growth. As a result, I came away with practical tools and guidance that I can immediately apply in my role to develop myself further and better support my team. Each session was thoughtfully followed up with a clear summary and encouraging words of support. Diane was consistently approachable, generous with her time and genuinely invested in our development.

A brilliantly delivered course from Diane, she makes you think and consider everything you do, this course is not just about your work life its about you as a person and how you interact with other people whether these are colleagues, customers or family. We bounded as a cohort too, which I did not expect to happen. Thank you Diane!

Diane is fantastic, she is truly engaging and ensures that the content of her sessions are tailored to suit both your individual and business needs. She involves everyone in the discussion and takes time outside of the sessions to work with you. I cannot recommend her highly enough.

This was an absolutely fantastic course. Diane puts things in a down to earth manor which people can relate to easily. I've always been sceptical regarding Personal Development style courses but I found myself being thoroughly engaged and really enjoying, taking on board and utilising the skills Diane has taught. Fantastic, can't highly recommend this and Diane enough 5 stars!!!

I wouldn't hesitate in recommending Diane, a very worthwhile use of our time as a young SLT and some new to management. Enjoyable too! Thanks Diane.

Cannot thank Diane Mason and the DMM Training and Development Ltd material enough. Our journey as a management team has just commenced and the last three months of sessions have truly catapulted us on a forward trajectory that will assist us to grow and thrive. We have only just scratched the surface of our journey and we are excited to see where it takes us. I would firmly recommend Diane and DMM to any organisation. The session to session knowledge, experience and OOH support going above and beyond is second to none. From a professional and personal level, thank you for all the support!
