Are Patient First doctors real doctors?

I am going to Patient First tomorrow because of this reoccurring cold sore problem to find out what it is. I know it's not an STD because when I went to the female doctor they tested me and never called about anything negative they found. I've been there before and said nothing is wrong when I had the swine flu which frustrated me. Should i save my time/money on a real doctor from a hospital or other office?
