Axel Meierhoefer
We worked together  •  Participant, Friday business lunch network.
I have been working with Jonathan the last three years and witnessed is rapid ascend as a thought leader. He has amazing energy and found a ... way to combine the needs above the waterline, where the content, data, facts and numbers live, with the often under-served area under the waterline where human connection, relationships, empathy, and engagement live. Combining scientific knowledge with leadership qualities is Jonathan's strength and a great resource for anyone seeking his advice. I wholeheartedly endorse Jonathan.

Axel Meierhoefer
We worked together  •  Participant, Friday business lunch network.
I've had the pleasure of working with Axel for the past 3 years where he has been consulting with our team in the creation of a new training ... methodology as part of a international technology transfer project with a communicated €500MM capital budget. The new methodology has been an undisputed success for 3 years running, and has been specifically recognized by senior executives within Bayer. Axel has also created a coaching program for high potential candidates that has elicited strong positive feedback. Lastly, Axel has helped me hone and develop my leadership style and presence. I enthusiastically endorse Axel a individual who can creatively solve complex problems, create solutions, and demonstrate leadership ability.
