Miyoko speaks 1.1

Our speakers program provides a valuable opportunity to hear the latest on health and nutrition from our medical doctors, and to ask questions.

The following local medical doctors all support the idea that a vegetarian diet is much better for your health than the standard meat-laden American diet.

Here are the doctors who presented at Vegfest 2019.

Patricia McEachrane-Gross M.D.

Dr Patricia McEachrane-Gross, M.D.

Dr McEachrane-Gross, or Dr McG as she is known, brings a new and unique philosophy to family medicine, combining elements of an old-fashioned doctor’s office with modern medicine and a holistic, common-sense approach to health and well being. Dr. McG is board-certified in family medicine and preventive medicine. She grew up and attended medical school in the Caribbean, and completed her Family Practice residency at the JFK Medical Center in Edison, New Jersey.

“I call my philosophy functional medicine,” says Dr. McG, who has both a medical degree and a Masters of Public Health (M.D.H.) degree among her credentials. “It’s a philosophy that’s been around for a number of years, but it’s becoming a new approach to medicine.” Educating patients about proper diet and lifestyle is a major component of her practice, she says. “Most of our chronic diseases, whether it’s high blood pressure, diabetes, arthritis, heart disease, cancer – all of them have a lifestyle basis. Yes, there are some heredity aspects. But the majority of the causes are based in lifestyle and diet.”
