2009 Field Season Consultant Survey

The 2009 Field Season Consultant Survey was mailed out in January 2010. The results of that survey are now available for viewing online here or you can download the written report. The results of this survey will be compared to the 2007 Field Season Consultant Survey and compiled. A report of compariative findings will be posted when complete.
