Dr. Eric Nazarenko, DC, CACCP
Dr. Eric Nazarenko, DC, CACCP uses chiropractic care to improve the health and wellness in all areas of patient’s lives, whether they are having problems with back pain or neck pain, or just want to start feeling better when they wake up in the morning.
Dr. Nazarenko, DC, CACCP takes a “whole person” approach in chiropractic care, which means looking for the underlying causes of disease, discomfort, and pain, as opposed to just treating the symptoms. Many seemingly unrelated symptoms often arise from imbalances in the spinal column, and Dr. Nazarenko, DC, CACCP will be able to determine the root of the pain and create a personalized chiropractic and wellness plan to suit each patient’s individual needs. Under the supervision and care of our caring and skilled chiropractor, patients report higher functioning in all areas of their lives. Because of Dr. Nazarenko’s extensive training in pre- and post-doctoral studies, we see amazing results in our clinic.
Dr. Eric Nazarenko, DC, CACCP adopts a functional medicine approach to understanding health. In addition to chiropractic care, he is leader in the area of gut health and food sensitivities. Gut health underlies many chronic diseases including autoimmunity, eczema, ADHD, and other digestive, neurological, and behavioral problems. Dr. Eric works with patients to transform their health through dietary and lifestyle change. He and his wife, Dr. Andrea Nazarenko, PhD, have written a book to help families regain health through gut healing.

Dr. Andrea Nazarenko, PhD
Dr. Andrea Nazarenko is the co-owner at Old Mill Chiropractic & Family Wellness. She is also the international bestselling author of When Food Hurts. She obtained her PhD in Clinical-Community Psychology, with a concentration in quantitative methods, from University of South Carolina (USC), as well as Masters Degrees in Psychology in Education (Columbia University, NY), Clinical-Community Psychology (USC), and Applied Statistics (USC). As a community and quantitative psychologist, her background is in the study of the how maladaptive and antisocial behaviors develop, particularly among serious and violent youth offenders; and in the development of statistical models that help us answer complex questions, such as why people respond differently to the same treatment or why people exposed to similar risks turn out differently.
Her current work focuses on helping organizations, mostly healthcare systems and governmental agencies, implement new practices and policies with quality. She is discouraged by the mediocracy of behavioral and physical health services in this country and worldwide and develops systems to bridge the gap between what we know in research and how we implement it in practice. The goal is to improve quality to improve outcomes. Her current projects include working with the Ministries of Health in Thailand to implement a physical activity intervention to improve health among dementia patients, working with the Commissioner of Health in Nigeria to improve the quality of maternal care for babies with Sickle Cell Disease, and participates in a national consortium to improve the quality of care provided to adolescents and adults with Sickle Cell Disease in the United States. She additionally conducts data analysis for the implementation of prevention programming in the United States Air Force and is the quantitative psychologist on a grant assessing how ready health centers are to screen for colorectal cancer. Above all, her heart is in the world of gentle parenting and spreading knowledge about the benefits of natural approaches to health. She is the biostatistical consultant to the International Chiropractic Pediatric Association and conducts research on the effectiveness of chiropractic with pediatric populations.
Her passion lies in activating her community to live the best life possible, and her mission is to spread knowledge about natural healthcare and supporting the physical and emotional health of children.
