Can  you help me do some detective work?  I am trying to locate the residential address for Ken Fisher, the executive chairman and co-chief investment officer of Fisher Investments.

Ken Fisher's residential address is unknown. However, Fisher Investments is headquartered in Woodside, California and Ken Fisher is known to frequent that area. We can also check records for fisherinvestments.com to see if they include his residential address, or contact Fisher Investments directly to inquire about his residence. Another option is to check local property records to see if his residence is listed.
