I’m a Clinical Psychologist in private practice in New York City. A main focus in my clinical practice is to help people become aware of mind-body interactions, especially their ‘gut feelings’ and other physical manifestations of their emotions, to be able to grow to be their true selves.
In an earlier phase of my life I was engaged in social science research projects at the Department of Medical Genetics, New York State Psychiatric Institute; Massachusetts Mental Health Center, Harvard University Medical School; The Medical Foundation (Boston); the Center for International Affairs, Massachusetts Institute of Technology; and the Stanford Research Institute. I was also Project Director for the Youth Leadership in Smoking Control Project under a National Interagency Council on Smoking and Health grant to the Lung Association of Mid-Maryland.
The Oriental Medicine Journal has published two of my articles: Successful Holistic Treatment of Clostridium Difficile Gut Infection: Case Study (2011) and The Microbiota-Gut-Brain Axis: The Constant Two-Way Communication Between Our Guts and Our Brains (2014). Many of the topics here are expanded versions of sections from the 2014 article. They’re identified at the bottom of the relevant pages.
In my  life as an artist, I make custom hand painted ceramic art tiles in my Hardin Tiles studio in New York City. I’m a life long cook – now developing healthier gluten free recipes. Some years ago I did catering for private clients – before I thought better of it – and more recently taught a gluten-free/dairy-free cooking workshop.
Other interests include yoga and Kinetic Awareness therapeutic ball work, meditation, travel, gardening (when I had one), cats and dogs, reading … and just generally learning new and interesting things.

The healer’s Hippocratic Oath instructing physicians to do no harm or injustice to patients has always seemed to me to be of the utmost importance. Yet doctors too often make dangerous risk-benefit calculations when prescribing drugs for their patients – even when excellent non-pharmaceutical alternatives are available.



Years of unhappy encounters with Western pharmaceutical treatments for various ailments of mine, my family, pets and patients gradually led me to seek more information and healthier alternatives that were more effective and didn’t cause collateral damage often worse than the original problem. The adjective iatrogenic, meaning  ‘induced inadvertently by a physician or surgeon or by medical treatment or diagnostic procedures’, has become necessary all too often these days to describe deleterious side effects from the practice of medicine.
My deep thanks to the many people who have been my teachers over the years – too numerous to name all of them here. I owe special thanks to Dr Denice Hilty, Carol Hornig, Dr David Miller, Ellen Saltonstall and Na’ama Yehuda.
