We specialize in diagnosing and managing a wide range of gastrointestinal conditions, including disorders of the upper gastrointestinal tract such as reflux (GERD), Barrett’s esophagus, eosinophilic esophagitis, and swallowing difficulties. We also treat stomach ulcers, Helicobacter pylori infections, and cyclic vomiting syndrome, as well as celiac disease, small intestinal bacterial overgrowth (SIBO), gut microbiome disorders, inflammatory bowel disease, and irritable bowel syndrome (IBS), including post-infectious IBS (PI-IBS). Our practice has unique expertise in diagnosing and treating intestinal infections and post-travel diseases such as malaria, leptospirosis, leishmaniasis, and typhoid fever, among others.
Clinic services
In-House Laboratory
Our physician-office laboratory is CLIA-certified, meeting the standards of hospital and commercial laboratories. We provide same day test results, often within just a few hours of sample collection.
For our patients or for patients with a referral from another provider, we are able to run stool samples on the BioFire FilmArray GI Panel, which tests for 22 of the most common gastrointestinal pathogens causing diarrhea and stomach distress.
Our in-office diagnostic PCR laboratory is the only place in New York to provide same day results for gastrointestinal and respiratory specimens, with results available often within hours.
Endoscopic Procedures
An endoscopic procedure is an outpatient procedure during which a thin flexible tube (colonoscope or gastroscope) is used to view the inside of your gastrointestinal tract. Endoscopic procedures include colonoscopy, flexible sigmoidoscopy, and upper gastrointestinal endoscopy or esophago-gastro-duodenoscopy (EGD).
House Calls
We are available to make house calls if you are unable to leave your home for any reason. For your convenience we can provide certain services at your home, hotel, or place of business.
