Jay is a teacher, photographer, maker, designer, dancer, musician, and best friend. (Well… everything except for the dancer part.) He lives in Blacksburg, VA with his wife and two children. Jay currently works for Virginia Tech as Technology Trainer and Knowledge Manager at the University Libraries. When he’s not working, Jay enjoys race photography, camping with his family, watching The West Wing and Ted Lasso, and making podcasts.

While Teresa’s heart will always stay rooted in Virginia, she has been a happy transplant to the Pacific Northwest since 2004. She currently lives outside of Portland, OR with her husband, two daughters and four-legged child, Max. She is a student, wife, mother, knitter, bibliophile, beer and wine enthusiast, and nature lover. She currently works at a non-profit milk bank and when she’s not working or studying, she can be found traipsing around the beautiful state of Oregon, hiking, looking for waterfalls, picking berries, and bravely dipping her toes into the frigid waters of the Pacific Ocean.
