Where do I find the dermatologist?

You must first have a referral from your Primary Care Provider. If, you already have an appointment, you can ask at the desk at Quarterdeck for directions to the Dematolgy department. (I beleive Dermatolgy is in the new section of the facility on the first floor.)

Go through your primal care doctor for reference

Enter at the Emergency or main entrance & follow the sign to the next hall on left to patients scheduling.
