Kentucky born and Georgia living, Mary has been in Columbus for about 11 years now.  She is finishing her Bachelor’s Degree of Fine Arts at Columbus State University this Fall. Focusing in photography, Mary has had a passion to photograph the world since she was about 10 years old.  When she isn’t running around with a camera, changing her hair color, or stressed about school, you can find her curled up with a book, chilling with friends, going on road trips or playing video games.  Mary has a passion for animals and loves to learn new facts about them.  Naturally, she has a “pet” moss ball named Mossmo.  Before she decided to major in art, Mary wanted to be a teacher for most of her life.  She still has a desire to teach, connect, and help others whenever she can.
