“I love working with patients, being part of their care. They inspire me and I learn so much from them,” says Dr. Letitia Cain, a naturopathic physician at Seattle Cancer Treatment & Wellness Center.
Dr. Cain says her overall goal for patients is to promote health and wellness—in body, mind and spirit. She recommends natural therapies, including vitamins, minerals, homeopathic medicines, and botanicals, that support the whole person and aid in building health.
A Fellow of the American Board of Naturopathic Oncology (FABNO), Dr. Cain earned a doctorate in naturopathic medicine from Bastyr University in Seattle.

She earned a bachelor’s degree at the University of Michigan, completed graduate coursework at Southeast Louisiana University in Hammond, Louisiana and post-baccalaureate premedical classes at Shoreline College in Seattle.
Dr. Cain joined the CTCA family in 2003 as a staff naturopath at Midwestern. In 2005, she stepped into the role of Director of Naturopathic Medicine at CTCA at Southwestern Regional Medical Center in Tulsa, Oklahoma. While there, she led a team of naturopaths and oversaw the hospital’s naturopathic residency program. In 2009, she became a part-time member of the CTCA team in Seattle, where she helps serve cancer patients in the Northwest.
Dr. Cain has been an adjunct faculty member at the Southwest College of Naturopathic Medicine in Tempe, Arizona.
