Hello, I’m Guillermo Castillo and thank you for your interest in our company. My father and I started Electrical Connections LLC in 2003. I attended Richard Montgomery High school and also studied at the University of Maryland University College business administration and finance. I am a blessed man married to my beautiful wife Maria and also blessed with my two children Belen and Guillermito. I have lived in Montgomery County almost all my life and feel this is the greatest place to live and raise a family. I feel it’s the diversity, the history, and the people that make living in our area so special.
