Tana is a Christian, nurse and average layperson. She stresses that she does not have any theological degrees, so the information she gathers and shares needs to be clear and direct.

Books like Until Heaven Then My Friend, written after delving into God's word about pets going to heaven, is so comforting because the truths found were evident even to an average layperson, like herself.

She also has written books about grief and reassurance when our loved ones have or are passing away.  They are based on her Christian insight and research as well as experience with people in the dying process in her three decades as a registered nurse,
