The conjunction in this sentence is the word 'and'
We refer to this conjunction as a coordinating conjunction, because it joins two words (or phrases) of equal rank - the noun teacher and the noun counselor, in this case. Other coordinating conjunctions include: but, nor, or, so, for, and yet.
To avoid confusion, word 'as' in this sentence is not a conjunction - it is a preposition we use when we describe the role/purpose/occupation of something/someone.
Subordinating conjunctions are used to introduce a subordinating clause, which is also not the case here. These include although, because, even though, etc.
