About Dr. Steinberg

Dr. Steinberg holds MD and PhD degrees and practices as a holistic gastroenterologist. She trained at Yale, Mount Sinai, the Institute for Functional Medicine and Parsley Health, and is an IFM-certified functional medicine doctor. She practices through Gut Instinct Health and sees patients anywhere in New York state by video.

One reason she became a gastroenterologist is that people appreciate a functioning GI system every single day. Functional medicine let her branch out beyond treating only GI complaints. She came to appreciate the impact of nutrition, environment, stress and trauma on the gut.

She was affiliated with Parsley Health at the time of a 2022 study on the Parsley Symptom Index.
