She comes from a science background, with her parents holding multiple degrees in computing and physics, which provided her with a wonderful background to approach veterinary medicine with an integrated approach, offering bioresonance. She lives in Petaluma with her husband Carlton, their family dog, Jaxx and their adventurous cat, Spencer.
