About Thayer Nasereddin, M.D.

While Dr. Nasereddin treats a wide range of gastrointestinal issues, his primary focus lies in advanced interventional endoscopy procedures.

Additionally, he has extensive experience in managing pancreaticobiliary diseases, gastrointestinal oncology, Barrett's esophagus, luminal tract strictures and obstructions, large polyp resections, and gastroesophageal reflux disease. By staying at the forefront of these advanced interventions, he strives to provide his patients with the most effective and innovative treatment options available.

Dr. Nasereddin values his patients’ background, their history, and he is driven to recognize and honor the uniqueness of each individual with the specialized care he provides. He believes in educating his patients about their conditions and the available treatment options, enabling them to make well-informed decisions about their healthcare journey. He works to engage his patients in the decision-making process and work together to develop personalized management plans.

In his free time, Dr. Nasereddin finds joy spending quality time with his wife and two children. Dr. Nasereddin also enjoy traveling, engaging in outdoor activities, reading, attending professional sporting events, and pursuing his hobby of video editing/filmmaking.
