With her knowledge in the medical sciences and her training as a Plant Spirit Medicine practitioner, Dr. Preston works to weave together a process of healing that is unique for each client. By addressing the source of the imbalance the result is the restoration of health and wellness on all levels.

In her free time Dr. Preston enjoys going for walks, reading books, cooking and spending time with friends.
