A devout Christian, part of Kathy's practice is praying for her patients, Daria included. Kathy is married and has a dog, a terrier named Benji. Kathy also has some knowledge of survivalist tactics, which she became interested in after reading the first novel of the Ashes series, Out Of The Ashes, and picking up tips from the exploits of the main character, Ben Raines.
