I don't agree with cat. In order to be a manager you need to have the talents that a manager needs.. whether its dental or not. Talents are god-given. Skills are learned. If you have the talent to coach, multitask, make sound judgement and decision making, and are an excellent multitasker that can get results the rest can be taught.
The TRICK is.. while being on the job and still "learning" it does hinder the respect that your team will give you. Its not good to be a "manager" and ask your staff for help on something you are unsure of. I would definitely try to get a job where extensive training happens BEFORE being placed into the role. This will eliminate the "Can you help me figure this out" moments you may have with staff, and it will also give you people to call when you might be in need of help. I have experienced many people in my career being great managers and not coming with a dental background. Some of the best ideas come from new people who haven't been stuck in "dental" thinking for long periods of time.
