“Esther is a enthusiastic speaker, easy to work with and clear in her communication. In her lectures she provides lots of easy to implement ideas. Interaction with the audience is something that she does really well. I already work with Esther for almost 15 years and she did always an awesome job. She can speak about many subjects and is up to because she is still a vet-tech (already for 25 years full-time)”.
