Eight years ago, Buffie became severely ill. In the blink of an eye, Buffie's bubbly personality that her friends knew and loved seemed to disappear. She was overcome with chronic fatigue, joint pain, skin rashes, mouth sores, and hair loss. After a year of testing, she was diagnosed with lupus. Buffie is a National Ambassador for The Lupus Foundation of America. She supports initiatives to raise awareness and funds for lupus research. Buffie is happily married to the love of her life, Dr. David. Purselle. They have two fur babies, Louie, a four-year-old toy poodle, and Prada, a two-year-old Labradoodle. She lives by the motto, "If you look for the bad in people, you will surely find it," so she chooses to look for the good.
