One of the most important things if finding somebody who actually understand Adult ADD. MDs, Psychologists and in some states social workers can diagnose ADD.

A couple of places to begin to look for help are www.add.org and www.addconsults.com

Another great way to find a professional who understands Adult ADD is by word of mouth. You could try to find a local ADD Support group and ask for reccomendations. A a great place to hook up with local people who have adult ADD is through http://adultadd.meetup.com
