I found out about the National Association of Free Clinics via MSNBC's Countdown and have stayed updated via the show and the NAFC's web page. The upcoming free clinics are listed below:
August 4th, 2010 -- Washington D.C. -- one day clinic
August 31st - September 1st -- New Orleans, LA -- two day clinic
Please see the NAFC's web page to either donate, volunteer, or set up an appointment to be seen at these clinics.
