Southern Marin

Richardson Bay Audubon Center & Sanctuary


Once upon a time, Richardson Bay was headed to a life as a business area and residential marina. But concerned citizens rushed to its defense and purchased the land to create a sanctuary for birds and other water wildlife. The bay is open to everyone, so long as you don’t disturb any winter birds in hibernation.

What got you interested in philanthropy?
Giving is an expression of spiritual gratitude that makes the world a better place for everyone. I have a huge soft spot in my heart for children and so I’m compelled to give to those organizations.
Do you have a favorite charity?
Tribe Rising India is working to lift the Santal tribe out of abject poverty through education. By building the first-ever high school dedicated to Santals, they are overcoming caste prejudice and creating generational change. 
Why is it important for someone to give?
I believe our gifts are meant to be shared. When we do, we change individual lives and also impact our world.
