Melissa Acosta

Community Educator

Melissa joined the team on April 1st,2022 as a Fellow for the Alliance for Watershed Education though Berks Nature. She onboarded the team permanently in August 2022 as a Community Educator for Berks Nature. Her goal is to expand our reach to community members who have not recently been engaged in our organization, whether it be from a lack of outreach in new locations or due to a language barrier.  As a bilingual speaker Melissa feels so excited to open the door for Spanish speakers to join our efforts with the environment.

Before she lived in Pennsylvania, Melissa lived in NYC where she previously worked for another non-profit organization named Greenpeace. In 2017 she had a life changing camping experience on the Virgin Islands where she came to the realization that environmental conservation has always been dear to Melissa since she was a child.  She knew she was on the right path and made a vow to continue her work to conserve mother nature throughout her life. Melissa is honored to be able to continue this work even after she has moved out of NYC and into the city of Reading. She believes if we continue to ‘Think Globally and Act Locally’ we can be the difference we need and want to see for our future.
