What leaders say
As CEO, I realised that whilst we had the individual talent in the team, we hadn’t yet found a way to get the best out of each other and work as a team. Now, 18 months on, we continue to grow and build on our success, ready for the next chapter in our business plan. Without Marie’s insight and input, I doubt very much if we would have got to where we are
The session broadened our knowledge of communication by increasing our awareness of how knowledge is communicated and received by others. This will enhance the efficiency of our company. A massive thank you to Dr. Stopforth for an engaging and informative afternoon.
We had the pleasure of Marie running a team coaching session with us. The session was focused on communication. We discussed what communication meant to us, explored real-life scenarios where miscommunication occurred, and identified where we could improve.
