KEEN is an NGO that was started in 1995 by an American teacher called Dick Wechter. At that time it was called CLEAN (Careful Learning from the Environment and Nature). Within a span of 2 years of inception, the NGO was managing the waste of 300 houses across the Landour the Landour. In 2005 Dana Crider, a maths teacher teaching at the Woodstock School, Mussoorie and a close friend of Mr. Dick Wechter, took over the management of KEEN and formed a fresh committee and members of the board. This is when the organization was registered as an NGO by the name of KEEN (Keeping the Environment Ecologically Natural).
