Honestly, if you can go anywhere else, I would recommend to do so.
Having horrific, rude, and incompetent staff in an office that is supposed to help treat mental illnesses isn't the best idea. Tack that on to the ridiculous wait times, terrible scheduling, lack of accommodation, and the fact that you'll never see the same physician twice, I think we've got the worst medical practice in Las Vegas on our hands.
I'm not a very picky person, but this office is seriously the worst. If you are just receiving a prescription, see if you can get it through your primary care doctor. If you are going for therapy, I would steer clear of this place and go literally anywhere else.
