Thank you for your interest in AAC evaluations.  At this time, our specialist in this area, Dr. Ann Ratcliff has retired as of August 2016.  We are working on finding a replacement.  At this time, AAC evaluations are limited and we have quite a long waiting list, approximately one year.  We understand the importance of these evaluations and wanted to update you in case you needed to seek a more immediate evaluation.  To our knowledge there are other agencies in the state that provide such evaluations.  Please see the links below.  This is not an exhaustive list, but one that may be a start:
