I wasn't able to pull fresh web data this turn due to a tool-usage limit, and I don't have reliable, specific knowledge of this particular practice ("San Francisco Dermatology" at sfskin.com) to share confidently. Rather than guess, I'd recommend checking their website (sfskin.com) directly, along with Google Business/Yelp listings, for current details like provider names, services offered, accepted insurance, and patient reviews. If you'd like, I can try searching again to give you an up-to-date summary.
