Education, mentorship and the inclusion of youth as much as possible in our activities

Honesty and respect when presenting fact-based research and educating our community


A clean and healthy environment is vital to the health of our communities.

Human activities impact the natural environment and contribute to climate change and pollution that directly affects human health

Individual, community and governmental actions can mitigate the negative environmental impacts of human activities

We can arrest human caused climate change and environmental degradation by individual, community and legislative action 




Suresh Venkatraman

President, Board

Suresh’s daughters’ engagement in environmental causes were a major influence to join GreenTown. Youth all over the world are asking us, the current stewards, to do everything we can to reverse our effect on the planet’s environments and climate. Actions by individuals, communities, and governments must all come together to accomplish this monumental but achievable task. Suresh is passionate that we become acutely conscious of our consumption – from energy to products, from how they are manufactured, packaged to how they are disposed of – and make decisions and take actions to minimize our footprint.


Connie Miller

Vice President, Board

Clean Air Lead

As a Bay Area native and Los Altos resident who has spent her entire life enjoying the abundance of nature our region offers, Connie sees the urgent need to act boldly to create a sustainable and thriving environment for our children. All actions start with one person and grow into a collective wave of change. Connie believes Los Altos and Los Altos Hills are perfectly poised, with their educated residents, affluence and regional influence, to be the leaders of change and leave a lasting positive legacy for our planet. Through GreenTown Los Altos programs, education and policy influence, Connie hopes to be a resource for and inspire positive environmental change in others.


Don Weiden


Don’s career as a civil/environmental engineer and his personal enjoyment in wilderness camping since grade school have led to his interest in minimizing the impacts of our engineered and human activities on the natural environment.   He became interested in GreenTown Los Altos when investigating residential solar panels for his home and is now a proponent of converting vehicles and equipment from using fossil fuels to clean electrical energy.  


Kim Jelfs

Board Member

Zero Waste Lead

Kim first became involved with GreenTown through our "Skip the Straw' campaign and hasn't looked back! She loved our hands-on, "can do" approach and immediately felt at home. A former H.R. Manager, she has volunteered in schools and local communities and is passionate about waste reduction, eliminating single-use plastics, and living sustainably. When not growing food in her garden, you can find Kim hiking local trails and traveling. 


Gary Hedden

Past President, Board Member

Conservation Lead

Gary joined GreenTown in 2011 and now leads the effort to protect our natural resources. That means planting trees, cleaning creeks and advocating for sound conservation policies. He still likes to bike, and leads the Historic Homes Bike Ride, the Native Garden Bike Tour, the Hardy Jones Memorial Bike Ride, and the Summer & Winter Solstice night bike rides.


Glenda Chang

Board Member

Water Lead, Eating Green Lead

Glenda is a long-time reef and ocean conservation advocate, and pursues the Sustainable Development Goals, also known as the Global Goals. Change for a healthier planet can start at home, by young and old alike. As such, she is eager to learn, collaborate, and engage together as a community. Her interests include SCUBA diving, technological innovation, disaster relief, island nations and their people, discovering the outdoors, photography, and being foodies with her family. One of her recent projects is providing clean water to an indigenous mountain tribe.


Kris Jensen

Consulting Director, Development 

Kris is our quintessential perfect match. The living embodiment of an advocate, starting at age 13 by penning a note to Pres. Reagan protesting removing the White House’s solar panels. He lives sustainably, is a certified permaculture designer, gardens, cooks and does woodwork when he’s not guiding our community efforts. 


Michele Gerstel

Marketing Lead

Michele admits joining the GreenTown team was a no brainer. Why? Who wouldn’t want to be a part of a team of passionate, brilliant residents working to improve our community’s future? Marketing its programs are just plain fun. Not to mention rewarding. Enough to keep anyone smiling.


Jana Schlanker

Organization Lead

Jana is our organizational go to. Her smiling face makes it easy to make any request
and know it will be readily handled.  From managing our growing database, organizing volunteers and coordinating events, she has an eye for details that we enjoy having on board.
