“Zhong Li is a very engaging and personable trainer. He is very thoughtful and assuring with his teachings throughout the entire course. He is able to relate real life examples when the topics are more challenging and often offer extra tips and guidance to the group. His constant willingness to share and to go over and above the course to reach out to the students is commendable. I have gained a better perspective and understanding on DMS. Thank you very much Zhong Li.”
