The Trust is very much oriented towards serving the needs of young minds around the world. The Alumni Association was formally established in 2005 at the initiative of our College Principal Dr. Siva Kumar. A JKKNDCH Alumni Committee was created and this committee started looking for members. The first alumni meeting was organized in November 2012 under the leadership of JKKNDCH. The event was attended by students from various regions and some foreign alumni and that made it very popular.

Currently, the Alumni Association is headed by brand new committee members led by our current beloved Headmaster Dr. A. SivaKumar. The new alumni committee has already implemented various alumni activities and planned various programs for the near future. The institution has well-built academic facilities, modern laboratory facilities, activity centers, information resource libraries, sports infrastructure, separate residences for boys and girls, a general and dental hospital for health services and practices, and impulse placement cells to ensure a safe place for all students. The mission of the Alumni Association is to maintain a lifelong relationship with alumni through opportunities and benefits that encourage communication and engagement with the institution and encourage their contribution to the progress and success of the institution. The alumni vision is to gather the alumni of the entire department under one roof and build a strong alumni network in the alumni community. Engage current students with alumni and maintain an alumni database.
