Jane Gillam

I discovered the Amargosa through my work as an Inyo County visiting nurse.  On early-morning winter walks, the silence and the sunlight made me fall in love with this unique corner of the desert.  Now that I am retired, my participation in the Amargosa Conservancy has become a meaningful way for me to live to my values.

Since joining the Board, I have discovered there are two goals for the Conservancy to which I can apply my efforts.  I want to help build the community of people who love the Amargosa and care about its future.  I also want to make certain the Conservancy, as advocate for the Amargosa, continues long into the future.
