General Information

A gastroenterologist is a type of medical specialist that focuses on diseases of the digestive tract (the esophagus, stomach, small intestine, and colon) as well as the liver, pancreas, gallbladder, and most everything else inside the abdomen. Becoming a gastroenterologist requires an additional three years of training after completing an internship and residency program in internal medicine.

Precision Digestive Care is a solo practice, meaning there is only one doctor at the practice. This ensures excellent continuity of care and allows Dr. Gandolfo the ability to build stronger relationships with his patients than would be otherwise possible in a large group. As an independent practice, we also have the unique ability to rapidly respond to meet the needs of our patients in an always-changing healthcare environment.

Precision Digestive Care accepts most commercial insurance plans and Medicare. However since insurance plans change from time to time, we will ask for your insurance information when we schedule your appointment.

We currently accept the following insurance plans:

  • Aetna
  • Blue Cross Blue Shield
  • Cigna
  • Emblem
  • The Empire Plan
  • Fidelis
  • Magnacare
  • Medicare
  • Oxford
  • United Healthcare
  • US Family Plan/Tricare

Please bring a photo ID, your insurance card, a list of your medications, any pertinent health information and/or test results, any questions that you have for the doctor, and your copay.

Dr. Gandolfo performs most endoscopy and colonoscopy procedures at his AAAASF-accredited procedure suite located in the Central Street office. Dr. Gandolfo also has privileges to see patients and perform procedures at Huntington Hospital.
