As the only piano and organ store in Gwinnett County at that time, England Piano and Organ Company was used as "central office" for organizing membership and as a meeting facility. By the fall of 1977, the Gwinnett County Music Teachers Association had approximately twenty members, a charter, a Junior Music Club, and full participation in all the metro Atlanta and state wide functions.

Through the years, members of GCMTA have served in a variety of leadership positions in the state association, including two past GMTA presidents, Julie Kirksey and Susan Andrews. Not only are GCMTA members outstanding leaders, they are committed to a high standard of excellence in teaching. That standard was recognized in 2004 when long- standing member Jean Mann was named as Teacher of the Year for the Georgia Music Teachers Association.
