[Scan-DC] Wah frequencies?

[John Pak hotmail]

Greetings,
I was wondering if any one had frequencies for Washington Advantest Hospital in Tokoma Park Md?
In particular am looking for the security frequencies.
If pls and off sets are available that also would be helpful.
As a point of interest, Columbia Union College Security which is located across from Wah is now being dispatched by Wah Security.
I'd appreciate any help.
