She is also called the Bluebird Lady and has done many conservation projects in many areas in Ohio. In her day job, Darlene is Executive Assistant to the CIO at Cardinal Health. Spending time with her family is very important in her life.

Ann Petrushka

Ann Petrushka joined OYBC in the Spring of 2018. She was previously a board member of East Central (Ohio) Audubon. As a 3rd grade instructor at Northridge Primary in Alexandria, Ohio, she coordinates and leads “Earth Week” at the Primary. This is a week set aside each year that focuses on environmental studies and nature. Activities include outdoor nature study, presentations from visiting speakers, and live animal education programs. In addition to working with the OYBC, Ann enjoys birding, biking,  hiking, creeking, and traveling.

Warren Grody

Warren Grody became a birder by accident.  On a lark, his wife Linda bought him a pair of Bushnell 10x 50 binoculars for Christmas.  Not long after, he identified an American Coot in his community pond and he was hooked.  Since then, he has volunteered for Columbus Audubon at Green Lawn Cemetery for the past decade, served two terms on the CA Board, during which he was Treasurer for two years, and he has chaired the John Wilson Memorial Education Fund since its inception.  In his spare time, Warren is an education lawyer at the law firm of Bricker & Eckler.

Maria Dellapina

Maria Dellapina is passionate about conservation and making engagement with the natural world accessible for all. She has education and experience in ecological research and environmental education and finds volunteering with OYBC a great way to mentor the conservation leaders of tomorrow. When not birding, Maria is the Training and Satellite Manager at Local Matters, where she works to create food system change throughout Ohio via food education, access and advocacy. Maria loves birds just as much as she loves cooking and gardening; two things she teaches at her job. Whether it is birding, cooking or gardening, Maria is always looking for easy ways to help people connect, appreciate and protect our common home.
