Effective albeit old-fashioned.
The good: "Dr. Dan" has been practicing since dinosaurs roamed the earth. He has seen it all and you can always rest assured regarding accurate diagnoses et cetera.
The bad: He is old-fashioned in his views on women and gynecology.
The ugly: These views will influence how he treats you.
I know people (even in my own family) who think that "Dr. Dan" hung the moon, but if you want something that is outside of what he expects women to do with themselves, he shows his true colors.
Personal examples? Due to a psychiactric condition, I felt that I should try going off of hormonal birth control; additionally, I do not wish to ever conceive children. As a result, I asked him for a tubal ligation, which he refused to perform because I had no children already. When I expressed my reasoning as to why I chose not to produce children, and explained that if I ever wanted children I would adopt them, he told me -- and this is very nearly, if not exactly, his reply -- "Well, you don't want to do that, because there aren't enough healthy white babies out there."
Yes, he went there.
And besides, as he told me, all women generally needed to be on hormones anyway, and if he had his way, any woman who worked for him would be on the pill because it made them essentially more manageable. He also is one of those old-school doctors who view menopause as a disease, and will inevitably throw hormones at you regardless of how they may negatively affect you.
