Locations and Hours
Monday, Tuesday, Wednesday 9 am to 5 pm. New adult and pediatric patients are typically seen in the mornings for longer appointment times with the physician. Because Dr. Srivastava holds unique Board Certification in both Allergy-Immunology and (Ped) Gastroenterology/Nutrition, all new patients require a note (not a referral) from their physician describing the reasons for the visit (gastrointestinal; allergy-immunology; or both). Patients sent for both Allergy-Immunology and Gastroenterology will require separate visit dates for their initial appointments. Patients initially seen for one specialty may choose to later be seen for the other specialty, but another note will be required.
Office Staff Hours
8 am to 5 pm Monday, Tuesday, Wedneday; 8 am to 4 pm Thursday, Friday. 24/7 Answering Service: for after-hours/weekend/holiday emergencies 716-688-0525 to reach the physician on call.
As a solo private specialty practice, all gastrointestinal procedures are performed at the hospital by and under Dr. Srivastava. Because this specialty practice uniquely serves both adults and children with complex gastrointestinal disorders, we have arranged to have endoscopy appointments available for our patients at the John R. Oishei Children’s Hospital and Millard Fillmore Suburban, with general anesthesia or moderate sedation, depending on individual needs and insurance approval when required. Not all procedures are available at all hospitals, because of variability in equipment owned and maintained by the hospitals. Currently, procedures are performed on Thursdays and Fridays 9a-5p.
