Ariel Mastrich, ND

Dr. Ariel Mastrich was born in New York and transplanted to the west coast years later. It was in Oregon, where she first discovered naturopathic medicine and holistic health care. She was introduced to herbal medicine and homeopathy, which showed her the body's amazing ability to heal itself without pharmaceuticals. This piqued her interest in natural medicine and started her journey towards becoming a physician. Dr. Mastrich earned her Bachelors of Science in Sports Medicine & Biomedical Science from Colorado State University in Fort Collins, Colorado. Afterwards, she returned to Oregon to obtain her Naturopathic Medical Degree.

Dr. Mastrich earned her Naturopathic medical degree from the National College of Natural Medicine (NCNM) in Portland, Oregon. While attending NCNM, her passion for nutrition and botanical medicine allowed her to develop into a practitioner who strives to find the cause of the body's suffering and develop strategies to bring the body back to a state of balance. Prior to becoming a Naturopathic Physician, she had spent years in nursing, fostering compassion, patience, and honing communication skills to help relate to patients and their specific health needs.

Dr. Ariel loves working with children and their parents &/or guardians, in discussing current health issues, regular well-child physical exams, discussing vaccinations and working towards individualized health care for each & every child.
