I’ve had good experiences here at Triborough GI. They are clean, the staff is friendly, and the wait time doesn’t make me want to hang myself haha. I’ve seen Dr. Brun here and he is very patient, thorough and knowledgeable.

My boyfriend suffered for months with stomach pain, gas and digestive issues. One visit to Dr. Brun and he is feeling much, much better. Staff is all friendly, concerned, and knowledgeable. They made us feel at ease and made our visits comfortable. They were understanding of his feelings and pain. I reccomend them 100%!
Robin B.
Dr. Grosman was so awesome. I didn’t feel rush he answered all my concerns and was very kind in asking me if I had any more questions. There was just a peace within me even just walking into his office he was very calm and welcoming.
