He’s had the (202) 279-0806 number since at least 2013, prior to that (2011) only New York numbers.

I checked the D.C. address given and it was sold May 7, 2013. It’s a residential condo address. The current kmkhanlaw.com contact page does not list a D.C. number.

According to this site he bought the I St. SW condo in 2005.

So he maintained that D.C. address from 2005 through 2013.
