Alyssa Cantwell

Keeper/Volunteer Coordinator

Alyssa is a San Diego native, started at LTB as a volunteer in early 2015 before being hired as a part time keeper in April of 2016 and now full time as a keeper and volunteer coordinator. She has a degree in biology from the University of San Diego and a love for animals she received from her grandfather, a veterinarian. Alyssa previously worked as a tour guide for the San Diego Zoo, teaching guests about conservation and how they could make a difference.

Alyssa always knew she wanted to work with exotic animals. Here at LTB Alyssa is able to indulge her passion and help make a difference in the lives of those who need it most. “I never thought the saying ‘do what you love and you will never work a day in your life’ could possibly be true until I came here. These animals are pure love and I wouldn’t do anything else.”
