Dr. Andrew Day

Dr. Andrew became a naturopath after feeling generally unwell in his early twenties. After going to the doctor and being told that he was perfectly healthy, he started to experiment with changing his diet, reducing stress and using dietary supplements. It worked. Those changes made a huge differences in his quality of life and he wanted to help others feel as well as he was feeling. That’s when he decided to enroll in the Naturopathic medical program at Bastyr.
