    Very satisfied with my PCP, support staff and office location.

  • Reviewed on 5/29/2026

    In all honesty, I choose doctors who are female. Dr. Penberthy is knowledgeable, and I feel very comfortable with her. It is taking a little bit for me to get used to dealing with males when they come in and do a pre-consultation before she does. That was actually why I left before, but she is good enough to come back to. It's not that the males are incompetent or anything else, I'm just much more comfortable with a female. I will say the Doctor Who spoke to me before Dr. Penberthy was quite nice and attentive to my issue. I also appreciate the fact that the regular office I've been going to for the past three years couldn't get me in anytime soon, and Dr. Penworth's office saw me the same day because I was in pain. I was definitely impressed with that and made my yearly physical with her in August.
