Brenna began her writing career with Amelia Bedelia fanfiction on hand-stapled printer paper. Her early original work was entrusted to gel pens and floppy disks, then ballpoint and flash drives, and briefly, receipt paper from her first job. In her Academic Period, she produced dry and esoteric works for which she was awarded a master's degree. She has also dabbled in visual media, and her minimalist comic, Ice Cream Money from Grandma, hangs proudly on her grandmother's refrigerator. She resides in Texas, where she teaches for a living and bakes for fun.
