I do not know why someone from Genentech, located in South San Francisco, California; attempted to reach me on 5/2/16. I googled this number (650-225-1000) led me to this website: https://www.gene.com/contact-us/visit-us/s-san-francisco. I didn't bother to contact them back to inquire as they didn't leave a message for me to follow up either.
