Absolutely, in fact I came in from MD. My other option was Baltimore, but I opted for Philly as it's closer to where I work.
I simply called and made an appointment, telling them that I was interested in starting HRT. I was lucky in that there was a cancellation that had just occurred and I got in later that week (which I've since learned was a miracle).
I met with a PA, discussed my situation and he ordered blood tests (the lab is on site). He had me set an appointment to come back in a month.
A few days later the blood tests came back and using the online portal I got to see all of the details along with a note indicating that everything looked good enough to proceed.
So when I returned in a month I met with an intake person then with the PA again, then filled my prescriptions at the attached Walgreens and that was it. Beyond that I go back every four months or so for blood tests to make sure everything is ok.
One piece of advice- the place is particularly busy so I'd strongly suggest including ample time for your commute or you'll risk losing your appointment. They're pretty strict on lateness; twice I've seen them having to turn people away who had been running late, and the waiting room seems to nearly always be full (at least when I've gone).
