The Association for Frontotemporal Degeneration (AFTD )

Today, the diagnosis of frontotemporal degeneration (FTD) comes with no treatment and no cure. FTD is a rare disorder that causes impairment in personality, language, behavior and/or movement. It is a progressive disease that typically begins in the 40s-60s and thus affects family and finances in a way that the more common forms of dementia do not. AFTD is dedicated to funding research for the development of effective treatments and to developing resources and education programs for professionals and families and Colonial is a proud sponsor of the organization.

Upper Merion Tricentennial Mural Project

Upper Merion celebrated its 300-year anniversary in 2013, in part, by displaying a mural on the outside wall of Colonial Electric Supply's Customer Service Center in King of Prussia, PA.

    I have been working at Colonial Electric Supply full-time


    Colonial is very family friendly company to work for. Being a female here, I don't feel as I am treated any different then the men that work here. My boss is constantly asking if the situations I am in are comfortable and if not I need to address with him right away so they can be corrected (not that there has been any issues). If you work hard, you will be rewarded. I have moved up already once since I started three years ago.


    Being paid twice a month instead of every other Friday.
