Dr. Mari Sawai

Naturopathic Physician

Dr. Mari’s passion for healing began at a young age. She graduated from Arizona State University with her bachelor’s degree in Applied Biological Sciences. Upon graduation she immediately started classes at Southwest College of Naturopathic Medicine. By age 25 she completed her Doctorate studies.

During her first year in medical school Dr. Mari participated in a 5-day intensive where she completed her first green juice fast and permanently healed herself from chronic constipation and digestive distress. After healing her gut so quickly she was eager to learn everything about fasting and detoxification. In her last years of medical school, she devoted her focus to fasting and detoxification methods. After graduating she completed internships at TrueNorth Health Center in Santa Monica, CA and Hawaii Naturopathic retreat Center in Hawaii. Dr. Mari’s first venture was opening Omizu Medical Sanctuary on the big island of Hawaii where she specialized in water-only fasting, advanced detoxification, and IV therapy. She has supervised over 500 fasts and helped to cure her patients from conditions such as diabetes, obesity, hypertension, IBS, parasitic infection, sugar addiction, and more.

She moved to Maine in 2015 to get hitched, Dr. Mari and Isaac co-founded Maine Comprehensive Health Institute that same year! She is now the proud mother of two beautiful children, a handsome pup, sassy little bird, and a Russian tortoise.

Dr. Mari combines the principles and ethical standards of Naturopathic Medicine with Functional diagnostic and laboratory techniques. Her patients appreciate her Sherlock Holmes style pursuit of the root cause of illness. By the time patients make it to her they have usually been around the block a few times and are relieved to feel heard and supported. She looks forward to working with you and uncovering the obstacles blocking you from achieving your best health.

Areas of special interest include women’s health at all ages/ stages, thyroid dysfunction, GI disruption, and chronic illness including Lyme disease and chronic fatigue syndrome. Dr. Mari is also known for her love of injection therapies including prolozone, neural therapy, and trigger point injections to treat all types of pain.

Dr. Abby Walker


Dr. Abby started The University of Maine at Farmington with an early childhood education major in mind. It was a year later she switched her path to becoming a chiropractor. After her first adjustment at 19 years old, her chiropractor removed her nerve interference and gave her body a chance to heal and repair from years of suffering from multiple allergies. Dr. Abby could only smell skunk before that. Finishing her pre-med courses at UMF she then attended Palmer College of Chiropractic in Davenport, Iowa. She graduated in 2003 with a Doctorate of Chiropractic and Bachelor of Science degrees.

Her first year of practice was in Hartland, Maine before purchasing an existing office in Skowhegan. She diligently created professional relationships with her patients’ physicians, physical therapists and massage therapists.

While managing her practice Dr. Abby furthered her education with the ICPA4Kids. (International Chiropractic Pediatric Association) She enjoys teaching everyday how the body, however old or young, has the potential to heal at its optimum functional capacity when given the correct tools.

Dr. Abby is a strong advocate for patients taking control of their own health. Working in a wellness center like MaineCHI has been a life long dream to help ease patients’ health quest in one accessible place.
