Welcome to Dr. Thomas Gross Gastroenterology

For the last 20 years I have been dedicated to Gastroenterology, the care and study of the structure, functions, and diseases of digestive organs. These disorders may affect the esophagus (swallowing tube), stomach, small intestine, large intestine (colon), rectum, liver, gallbladder, or pancreas.


Gastroenterology is more commonly known as "GI" which stands for Gastroinstestinal. This site is full of information about our practice, procedures, paperwork, and more!


Office Hours

Open 7 days a week from 9:00 am to 5:00 pm



Dr. Gross does procedures Monday through Friday at Hendricks Regional Health. He sees scheduled appointments in his office on Saturdays and Sundays. Whenever possible, appointments are scheduled in advance. If an emergency or urgent situation arises, every effort will be made to evaluate the problem in the office or at the hospital. If it is necessary to cancel an appointment, please notify the office as early as possible. The office personnel are carefully trained to handle telephone calls. The receptionist may handle some calls or refer them to a nurse or physician.

If there is an emergency, call 911 or go to a hospital emergency room.


Prescription Refills

Please call the office between 8:30 am - 5:00 pm.
Requests should be made at least one week before your supply is gone.

Provide your name, birth date, pharmacy name, phone number, prescription number, drug name and dosage, as well as how often you take it. Please note that we do not refill routine prescriptions in the evening or on weekends. Nurse response generally occurs in the afternoon.
