If you are not familiar with the Silicon Valley Community Foundation you are doing yourself and your clients a disservice.
Check out their new, redesigned website at www.siliconvalleycf.org.
They are an excellent resource for charitable giving information, and they provide support and administration for various charitable trusts and foundations. They also have an excellent Donor Advised Fund many of our clients use.
No matter your client's situation, even if working with the community foundation or some other charitable organization, make sure that they work with a qualified charitable planning attorney to plan their gifting and create the necessary documents.
