Liz Whalen - Secretary

I am a biology teacher at Thomas Worthington High School and have taken students to Puerto Rico with WFSI's spring break program and chaperoned the Pacific Northwest trip.  I enjoy the quiet that comes with exploring our world and getting away from cities and towns.  I particularly enjoy fostering the opportunity for students to encounter the silence of nature in awe and wonder, in opposition to a world of Snapchat and constant music from headphones, where many people don't have silence for any part of the day.

I find peace and truth in nature.  In a society that is moving more and more toward technology, I find myself separated from reality and creation.  Returning to nature brings me back to what I was created for and helps me to re-align my priorities.
