His principal works are The Genie in Your Genes (YourGeniusGene.com), which reviews the research linking consciousness, emotion, and gene expression (USA BookNews “Best Health Book”), Mind to Matter (MindToMatter.com), which examines the science of peak mental states (American Book Fest “Best Health Book”), and Bliss Brain (BlissBrain.com), which demonstrates that “flow” states rapidly remodel the brain for happiness.
He has published many scientific papers in peer-reviewed journals, collaborating with scholars at various universities on outcome studies of posttraumatic stress disorder (PTSD), depression, and anxiety. He is the editor of the peer-reviewed journal Energy Psychology: Theory, Research, and Treatment (EnergyPsychologyJournal.org) and general manager of Energy Psychology Press, which maintains a research bibliography and case histories at EFT Universe (Research.EFTUniverse.com), one of the most-visited alternative medicine sites on the web. He is the science columnist for Unity magazine and his blog posts on the Huffington Post have been viewed by hundreds of thousands of readers.
In 2007, Church founded the National Institute for Integrative Healthcare (NIIH.org), a 501(c)(3) nonprofit institution dedicated to education and research on evidence-based healing modalities. The two primary methods he uses are EcoMeditation and Emotional Freedom Techniques (EFT acupressure tapping). He has worked with over a thousand pain clients, with average symptom reductions of 68% (Church & Brooks, 2010), and co-developed the Skinny Genes program which results in long-term weight loss (Church, Stapleton, et al., 2018).
In 2008 the National Institute for Integrative Healthcare initiated the Veterans Stress Project (StressProject.org), a clearinghouse to connect veterans suffering from PTSD with energy therapy practitioners. Over 21,000 veterans and family members have received counseling through the Project, and Church has twice been invited to testify before US Congressional committees on his work.
Church performed two pilot studies of EFT (Emotional Freedom Techniques) for posttraumatic stress disorder (PTSD; Church, 2010a; Church, Geronilla, & Dinter, 2009). They demonstrated highly significant results despite a small sample size, indicating a robust treatment effect. This led to a randomized controlled trial, published in the oldest peer-reviewed psychiatry journal in North America, showing highly significant results (Church, Hawk, et al., 2013). It demonstrated that 86% of veterans with clinical PTSD were subclinical after six sessions of EFT and remained so on follow-up.
