Daniel S. Deiseroth

Project Manager & President Emeritus
I knew I wanted to be in this business when I was 5 years-old driving in a dump truck with my father delivering supplies to construction sites. Since joining Gateway, I have acted in all roles in the company over the past 38 years. Currently, I act as a project manager for various types of expert and specialty projects that mostly involve my time. In addition, I mentor the PM’s working on projects for numerous clients I have obtained over the years making sure they receive the highest level of service and expertise they have come to expect when using Gateway. I am fortunate enough to have spent my whole career at Gateway from being an intern in 1984 and starting full employment in 1985.

When not at work, I enjoy spending family time with my wife and daughter, especially in New York City. I also enjoy all forms of exercise, but mostly kettlebells and biking. In the summer I mostly play golf and, in the winter, enjoy a trip out west to ski.
