To echo the other reviewers, Bill is simply wonderful.  We have been looking to purchase a house in the bay area for the last two years.  Other realtors were either too pushy, or simply didn't pay enough attention to what we were wanting from a home to guide us in the right direction.  Bill patiently answered all of our questions, calmed all our fears, and led us to the house we'll hopefully be living in for the next 20 years.  Not only did he find the house for us, but he cleverly structured our offer to make it very appealing to the seller.  If there were 10 stars, he'd get all ten.  I cannot recommend him enough.
