Quotable: “That clap of thunder you may have thought you just heard was not a climate event. Rather, it was an ear-splitting serve from Mark Krupkin. The Stanford community will love getting to know this young man who is eager to learn, improve and dive headfirst into the entire Stanford experience. We are excited to welcome Mark (and his world-class serve) to the Farm this fall. He is an exciting prospect whose best tennis is ahead of him.” – Paul Goldstein, Taube Family Director of Men’s Tennis
