Belief Statement

“No one will protect what they don't care about, and no one will care about what they have never experienced” - David Attenborough 

Humans are not separate from nature and we depend on nature for many unseen things like clean water and air. Therefore, it is our responsibility to be good stewards and protect what we can. But to do so, we must first experience and appreciate nature in all forms. 

Personal Interests/Anecdotes

Beth enjoys photography, running, identifying all the living things, and slowly making her home and yard more environmentally, and bay-friendly. 

Beth’s initial career goal was a big cat zookeeper. That goal quickly changed after taking a substitute teaching job for a non-public special education school. With a new purpose, she pursued her teaching credentials and happily taught at the middle school level for about 8 years. After a hiatus to raise her children and travel the world with her military husband, she decided to go back to school and follow her passion for the environment. Now, Beth’s focus is teaching all who will listen about the importance of our natural world and trying to help them understand how nature benefits us all. 

Beth earned her BS in Small Animal Science from Delaware Valley University in Pennsylvania and her MA in Biology (conservation) through the Advanced Inquiry Program from Miami University in Ohio. She holds two teaching credentials from the state of Maryland (Sp.Ed., Bio)

Vicki Petersen, Office Manager & Naturalist




Academic and Professional Credentials

B.A. Journalism, UMCP, MAT Notre Dame of Maryland University

Belief Statement

In any relationship, to take more than we give is not only unwise, it is unsustainable.

Personal Interests/Anecdotes

During the pandemic, when food items became scarce on grocery store shelves, she put her interest in self-sufficiency to work in her own backyard, sharing the bounty with family and friends. Her son raised chickens and she grew tomatoes, cucumbers, herbs, green beans, tomatillos and more.

Last year, she planted two apple trees and is turning her focus on landscaping with food. Why can't a yard be beautiful and practical?

She has lived in a local Bayside community for nearly 30 years and can often be found walking her dog, BG, along the waterfront.
