I recently got very fortunate through a family friend to be introduced to a Dentist and invited to intern at her office but was wondering if there was anything I should know before going in. I start in about a month roughly and I have no idea what I will really be doing (I'm guessing shadowing or front desk work) as I'm not out of highschool yet and have never had an actual professional job (mostly worked fast food). I was also told that most interns they get there will wear scrubs or business casual clothes, could someone please give me suggestions on where to look for scrubs or business casual clothes (that are reasonably priced).
