Working with Achieve CTC was super easy and always on equal footing. The trainings Cathrin delivered were very well received, and the feedback on both content and delivery was excellent. She handled last-minute changes and technical challenges with confidence and a good sense of humour.

Cathrin is very knowledgeable of her subject and has added great insight and experience to the development and delivery of the people aspects of this project. Anyone that needs learning and development support with their people should work with her.

Cathrin demonstrates a good balance of being intuitive, understanding, compassionate, but also directive with feedback when needed. I would recommend her for individual or team coaching and development based on my experience.
