Thanks, jebarne. Excellent question, and excellent opportunity for us to simply explain our model.
Since we're based outside Philly, our work in DC and NY is by travel. Upon launch, will will rent offices in DC and NY for one day each week and take appointments at homes and offices for those days as well. Before launch (which is still several months off) our visits will not be strictly periodic, but will be based on interest, hopefully from testers from this forum.
In DC in particular, we're looking at several options in the central business district. We will be asking for opinions on good locations on this thread, suggestions (as always) very welcome.
(Related: Interested NY members, would you prefer to meet us in Midtown, or Downtown?)
