I was reading your post and realized that you live in NoVa too and are going to the Philly FFC. I live in Arlington and make the 2 1/2 hour trip to the Philly FFC monthly. I'm going again on Jan 17th. I definitely reccommend going to your appointments in person. I made the mistake of doing the 2nd one over the phone. When it came time to get the labs done, no one in the NoVa/DC area knew what the tests were and I had to go to Philly anyways.
