Fun Facts
The best advice Dr. del Castillo has ever received is “Stay curious and never stop asking questions.”
The most exotic place she has visited is Costa Rica.
Not everyone knows this about Dr. del Castillo, but she grew up in Taiwan, spending the first 18 years of her life there before moving to the United States. She played on the high school varsity volleyball team as a setter and libero and competed against other international schools in East Asia, including Japan, Korea, and the Philippines.
Dr. del Castillo’s guilty pleasure is French fries – “anytime, anywhere, any kind!”
