Special Thank You to Katy Carter and Rebekah Cahoon!

We appreciate the dedication and hard work Katy has given to AVCS with almost 12 years of service as executive director.  Through Katy’s direction and leadership the agency has been reorganized into a well respected, sustainable small nonprofit with expanded access to mental health services for those underserved, and has encouraged prevention and health promotion through service, education advocacy.  During this period AVCS school contracts increased from 14 to 41 schools, hours of counseling provided at the schools increased from 3,500 to 20,000 per year, and number of clients serviced at the clinic increased from 875 to over 2,000 per year.

As AVCS Clinical Director and Controller, Rebekah provided direction, support and collaboration for over 9 years to help AVCS be the agency is today.   Rebekah’s commitment and amazing ability to take on both of these roles was remarkable. 

 Thank you both for all of your years of service to AVCS.  We wish both Katy and Rebekah the best in all that lies ahead!
