Dr Scearce was raised in Orange County, California. She had an interest in veterinary medicine when she was young, but changed her mind and studied International Relations and German at the University of California, Davis, with a mind toward a career in the State Department.

During a year of study abroad, she changed her mind and decided to apply to veterinary school. She earned her DVM from the University of California, Davis in 1999. Afterwards, she joined a mixed animal practice in Central California, with an emphasis on dairy medicine. After five years in that practice, she worked in a few small animal practices before settling at her current practice, where she has been for the last 17 years.

Looking for additional tools to help her hospice patients, she became certified in acupuncture by IVAS in 2015. She is also certified in Chinese herbal medicine by Chi University, and completed David Winston's two year program in Western herbal medicine. She has additional training in both Western herbal medicine and integrative oncology.

Currently, she continues to work in small animal practice and teaches with Dr Laurie Dohmen at Purple Moon Herbs and Studies.
