Pros
Great relationship development opportunities with clients, general and electrical contractors, as well as sales representatives, front-line workers, and management. The office in San Diego is pretty spacious, and they offer free coffee/tea as well as free food during monthly events (great news for broke post-grads like me). It is a great place to work for if you're interested in a niche industry, and my advice would be to learn as much as possible early on for career growth opportunities and promotions.
Cons
Pay could be a bit better considering the tasks that coordinators have. I started as an intern, and after hiring me on full-time I was offered the same pay (tough for San Diego). Sometimes, it feels like an IT position rather than a coordinator because of the tasks you take on. Things can get repetitive, but thankfully management is involved as much as you want them to be. Currently in a transition phase (previously owned by ADT but recently became independent). This has caused a lot of changes and confusion across the board.
