Still, I just checked their web page and they say 5th Floor with no mention of any suite number.
I will be going to Carson City sometime this year and will definitely pay them a visit.
When you spoke to someone was it an actual receptionist or the answering service? When I called them, the answering service did not identify herself as such (like when you call a doctor's office).
I wonder if they got a chair for that desk and phone? (haha)
