Giving Tree

The Britton Fund was established in 2006 in honor of John Britton, a much-loved and admired arborist. The Britton Fund strives to ensure a healthy and sustainable environment through research and education in the field of arboriculture. Nelda, Jim and Carol participate on the Board of Trustees and Advisory Committee.   Jim, John, and Nelda's daughter Phoebe have participated in the Britton FUNd Ride, an annual day-long cycling event that is one of the organizations's main fund-raisers.


In 2002 Nelda was diagnosed with chronic lymphocytic leukemia and has become an active supporter of the Leukemia and Lymphoma Society (LLS). LLS strives to eradicate blood cancers through research.  It also provides patient and family support to those who suffer  from this disease.  Team in Training is an LLS fund-raising program that facilitates endurance athletic events.  In the past five years, both Jim and Nelda have participated in a number of Team in Training walking, hiking, cycling, and triathalon events. Jim is currently working for the Triple Crown with TNT by completing three events. The third will be the Kaiser half marathon in San Francisco this spring.  You can donate to his event here.


Groundwork Opportunities (GO) is a nonprofit organization which implements micro-development projects in underdeveloped nations.  The projects, centered around sustainability and community impact, include building freshwater wells, providing post-genocide reconciliation strategies, and developing sustainable farms.  Ryan, Nelda's son, worked with GO in Tanzania, Uganda and Rwanda on agriculture, education, and human rights projects.




 Jane has chosen to support her goddaughter Megan's "The Daily Run" through The Ability Foundation, an organization which provides wheelchairs and other support to disabled peoples. Megan is an artist studying graphic arts at University in Utah and was born with cerebral palsy.  She was inspired to see disabled people participating in marathons and running with their family on their racing wheelchairs and designed The Daily Run to raise funds for her own running-chair. Her goal for a new chair would allow her to do what so many take for granted-- walk and run.




Carol and Gini, Michael's wife, are passionate about horses.  We've continued to support the National Wild Horse Assocation, a nonprofit whose mission is to ensure the wellfare and survival of wild horses and burros in an ecologically balanced environment.








John and his wife Morgana support Vida Verde (, a Bay Area organization that promotes educational equity by providing environmental learning experiences for inner-city students. Vida Verde takes low-income students on 3-day, 2-night outdoor educational camps where they hike among the redwoods and explore tide pools for the first time.


The Tree Research and Educational Endowment Fund (The TREE Fund) provides research grants, scholarships, and educational programs to advance knowledge in the field of arboriculture and urban forestry.  In 1991, Jim started Tour de Trees with a few comrades who rode their bikes from Seattle to Oakland, 100 miles per day, to raise money for tree research. John has been a participant on two of the subsequent 500+ mile rides.  






Ruth participated in Glide Floss Bridge to Bridge Run for the second year benefiting the Special Olympics and intends to participate in the next event in 2011. The Glide Floss Bridge to Bridge Run is a 7k through San Francisco and proceeds go to help the Special Olympics Northern California give athletic opportunities to people with disabilities. Ruth also participated in the Brenda Donato Rainbow 5K Fun Run & Walk honoring Brenda Donato, an extremely active member of the Leukemia & Lymphoma Society's Team in Training program who lost her battle with leukemia in April 2007. To support Ruth in her Bridge to Bridge Run, email her here.  Those interested in supporting the Leukemia & Lymphoma society please donate.
