My team and I had the pleasure of being coached by Susie in Berlin. Within a few days, she was able to promote substantial growth within my team. Boasting sharp awareness, she is in tune with the struggles that one may have and addresses those struggles with quick, accute solutions. Being a newcomer in my company, I often experienced draining spouts of insecurity and doubt in myself. Susie quickly took note, took the relationship that my team had, cultivated it, and influenced an evolution that instilled the confidence that I, as well as some of my fellow peers, had previously lacked for success. The most difficult part was seeing Susie go, but the impact that she left on my team and me will remain everlasting. Thank you, Susie!

I have the honour to work with Susie as a Trainer from RAIN Group for our Inside Sales Team of T-Systems International. Words can't really describe how much Susie has helped me personally to gain more confidence as a sales person, especially because I had no prior knowledge to sales itself, since I came from a totally different background. Susie taught me to believe in myself more, to use both my strength AND weakness, because we're all only human, and that it is the most important aspect of selling itself. I also really appreciate that Susie, even though she has a lot of knowledge in a lot of aspects (not only the niches!), she never once gave me the feeling that she was being condescending, but purely there to help me and my team to move forward. I can only recommend her enough to everyone that is interested and passionate in Sales to work with Susie!
