"If you’re looking for an auctioneer for a nonprofit event, look no further than Testarossa Winery owner Rob Jensen. He was the keynote speaker at a recent fundraiser for Palo Alto’s International School of the Peninsula and raised $40,000 for a luncheon tour of the winery at 300 College Ave. The bidding started at $3,000 and quickly jumped to $10,000. “It was the perfect opportunity to quadruple our donation and let the top four bidders win a luncheon for 10, bringing the total for that auction item up to $40,000,” Jensen said. The school, by the way, offers inquiry-based bilingual classes in French and Mandarin."
