Co-Owner  & Pet Care Specialist:  Kate Hall, Ph.D.

Kate has a dog, a cat, and a horse.  Having grown up riding horses, Kate dedicated several years of her life working with former race horses and various therapeutic riding programs in Massachusetts.  These riding programs, which help physically and mentally challenged youths develop remarkable and priceless bonds with equally remarkable horses, provided Kate with an immeasurably incredible experience.  Kate has also been involved with pet rescue organizations in Massachusetts, New York and Virginia. She earned her PhD in Public Policy at Virginia Commonwealth University back in 2016. In addition to owning and operating Tail Wags, Kate teaches several business management classes part time at the University of Maryland Global Campus. Recently, Kate also started an animal photography business! If you are looking for professional photos of your furry friends, feel free to reach out to her through her website at

Co-Owner & Pet Care Specialist:  Mary Markakis, M.A., M.F.A


Mary currently has one kitty, Bailey Hallmark.  Mary and her first pet, Sparky, shared an immediate bond; his untimely passing motivated Mary to become involved in various care/shelter organizations whose mission it was to protect and/or save animals from unsafe environments.  Mary has since been involved, in some way or another, with pet rescue organizations across the country, fostering, transporting, and volunteering to provide daily care and/or find homes for various animals in Pennsylvania, New York, Arkansas and Virginia.   Mary recently finished her MFA at George Mason University and now also teaches writing courses part time at American University.
