Dr. Bigsby became involved in chiropractic after a sports injury to herself. While qualifying for the Boston Marathon, she injured her iliotibial band. Thanks to chiropractic care, she made a full recovery, ran Boston and continues to run marathons to this day.

Dr. Bigsby attended the Veterinary Spinal Manipulative Therapy course at The Healing Oasis Wellness Center in Wisconsin in 2002. She participated in 200 hours of intensive coursework in small animal and equine chiropractic. She then received further certification by passing the testing by the American Veterinary Chiropractic Association. She has practiced chiropractic on a part-time basis since that time, incorporating it with her more traditional approach to veterinary medicine.
