Advanced Endoscopy

Delivering state-of-the-art care for acute, complex and malignant disease

GANV was first in Northern Virginia to establish an Advanced Endoscopy Clinic providing a comprehensive array of endoscopic services. The clinic functions in conjunction with Inova Fairfax Hospital’s Center for Advanced Endoscopy and is led by our interventional gastroentrologists, Medical Director, Dr. Behzad Kalaghchi, Dr. Byungki Kim, Dr. Mahmood Abedi, Dr. Iris Lee and Dr. NicholasM. Szary

Experienced in performing technically demanding and complex endoscopic procedures, our advanced endoscopists diagnose, stage and treat benign and malignant diseases of the digestive tract. Equipped with the newest technology and trained in the latest techniques, they are committed to maintaining an unsurpassed standard of care.

Responsive and Thorough

Our advanced endoscopists provide skilled, individual attention. To ensure an informed approach to care, they work closely with referring physicians to gain a complete picture of each patient’s medical history.

Our physicians are also accessible to referring physicians to discuss patient cases before, during or after care. Complete, detailed reports and progress updates are provided promptly, and all patients are returned to their referring physicians’ care once advanced endoscopy needs are resolved.
