“I have heard Mr. Sumerlin speak twice now. I found his presentations to be thought-provoking, motivational, and done in a way that is relatable to anyone. As I looked around the room during these presentations, I saw others in the group nodding their heads in agreement and really grasping the messages. He took the time to ask exactly what we were looking to accomplish through the presentation. He asked the challenges our organization faces and tied key elements from our employees’ work into the discussion. I was truly impressed and pleased with the presentations Mr. Sumerlin shared with us.”Erica Figueroa, Manager, Social Security Administration
