I do not think this organization really exists. I suspect that it is part of a tax fraud.
I have visited their location at 404 Main St., Gaithersburg MD, and I have never seen anyone there. The door is always locked, on weekends, weekdays, always. I left messages on their voice mail and got no response. They don't seem to have a phone anymore.
I am suspicious because the rent on the real estate in this neighborhood is quite expensive. No one could rent there for years, and never use the space unless something funny was going on.
