Dr Alyssa Marley ND

(Formerly Dr Alyssa Christoforou ND)

Dr Alyssa Marley ND received her Doctorate of Naturopathic Medicine in 2019 from Bastyr University in Seattle, Washington. At Bastyr, Dr. Marley honed her clinical skills through 800+ hours of primary care and specialty care rotations at the Bastyr Center for Natural Health and off-site community care clinics, 150+ hours of advanced preceptorships, and 300+ hours of advanced elective training and continuing education in the fields of gynecology, gastroenterology, diabetes and cardiovascular disease, oncology, pediatrics, and environmental medicine. She has additional specialty training in craniosacral therapy, Kinesio taping, biofeedback, and intravenous and injection therapy. Prior to attending Bastyr, Dr. Marley studied Biology and Anthropology at Fordham University in New York.

Dr. Marley’s passion for biology and anthropology, and the intersection of these disciplines, drew her to naturopathic medicine. She was fascinated by ancient people’s intricate understanding of the human body and the ways in which culture and society influenced health on a macroscopic level. Building on her own Greek and Polish roots, Dr. Marley integrates traditional healing wisdom with evidenced-based natural medicine interventions to treat the underlying cause of disease and address wellness on the physical, mental, emotional, and spiritual planes. Her guiding principle in practice is The Healing Power of Nature – both the intrinsic power of the body to heal itself and the extrinsic power of clean food, botanicals, water, air, and light to restore health and prevent disease and dysfunction. The result of her philosophy is a patient-centered, holistic, multidisciplinary approach to wellness.

Dr Alyssa Marley ND focuses on whole family health care, serving both female and male clients from infancy onward. Her practice primarily centers on hormonal imbalances including thyroid, adrenal, reproductive hormones and more; women’s health concerns such as irregular menstrual cycles, recurrent vaginal or urinary tract infections, premenstrual syndrome, polycystic ovary syndrome, fertility and preconception care; digestive disorders like acid reflux, small intestinal bacterial and fungal overgrowth, irritable bowel syndrome, and inflammatory bowel disease; autoimmune diseases such as Hashimoto’s disease, Celiac disease, rheumatoid arthritis and more; chronic infections including viral, bacterial, fungal, and tick-borne; and detoxification.

In her free time, Dr. Marley enjoys spending time in nature—hiking, cycling, and swimming—and in her kitchen cooking up delicious recipes and baking allergen-free desserts. She is a huge foodie and prides herself on finding the best healthy restaurants in cities across the globe. She loves to travel and frequently visits Cyprus and Poland where the majority of her family lives. After spending four years in the beautiful Pacific Northwest, Dr. Marley has been enjoying serving the Portsmouth community and exploring the White Mountains and New England seacoast.
