Other Information


Shortly after having served in the United States Marine Corps, I began my technology career in NJ as a Helpdesk Technician in 2001. Soon after, I began teaching Microsoft Systems Engineering courses on Windows 2000 at New Horizons Computer Learning Centers of NJ. In 2003 I moved to the DC Metro area to accept a Director of Technology position at Beauvoir The National Cathedral Elementary School, which I held for 13 years. I then moved on to a Solutions Engineer role at Carousel Industries in 2016 where I designed solutions for clients in many different verticals. After two years working from home as an SE, I realized that I missed being a part of a vibrant school community and feel extremely fortunate to have found this role so close to home. I am honored to be joining the CESJDS community.

I live here in Rockville and love spending time with my wife Tiffany, daughters Madison and Hailey, two dogs, and a few chickens. I am an avid grappler. I have been a wrestling coach since 2008 at St. Albans until 2015 and at St. Andrew’s from 2016 to 2018 and newly here at CESJDS. I am also a purple belt under Fernando Yamasaki in the gentle art of Brazilian Jiu-Jitsu which I have been practicing for about 8 years. I also love to travel and tap into my creative and artistic self, working with wood or paint or many other mediums.
