are highly skilled tradesmen. This is one of the trade professions where an apprenticeship is involved and required. An apprentice must work under the supervision of a licensed electrician for a specific period of time. The amount of time is determined by each licensing municipality.

They like what they do, take their work seriously, and are genuinely concerned for the safety of their clients. The state licensing tests are grueling and time-consuming.
