  • McKynzie B.

    “ The staff was so friendly, accommodating, and very kind. It was my first time having an appointment there and I was very well cared for. ”

  • Daniel R.

    “ The best queer general practice medical provider I’ve been to. They are always caring and candid which I appreciate and I have been seeing them for about 6 years. They’ve gone through tech and organizational changes, sure, but that hasn’t stopped them from their primary focus and knowledge regarding queer issues— far more than I can say from non-queer practices. ”
    – Daniel R.
