Planned Giving

Since the opening of the Brookfield Zoo in 1934, the Chicago Zoological Society (CZS) has set the global standard in animal care and conservation. And with an increasing need to protect the world’s threatened species and ecosystems, our mission to inspire conservation leadership by connecting people with wildlife and nature has never been more important.

Through planned giving, you may be able to structure a contribution that is larger than you ever thought possible. Did you know that, with proper planning, you may even increase the size of your estate while decreasing the tax burden your heirs will face?  Additionally, you can have the assurance your legacy will inspire generations to come as they experience a connection with wildlife and nature through the work of the Chicago Zoological Society.
