At Park Avenue Gastroenterology & Digestive Health, Dr. Zaffer specializes in preventing, diagnosing and treating digestive tract and liver disorders. By integrating the holistic and preventive approach of traditional Eastern medicine with the structured, evidence-based methods of Western medical education, Dr. Zaffer focuses on the whole patient, including lifestyle factors and mental health alongside physical examinations, lab tests and advanced gastrointestinal procedures. Unlike the administrative pressures present in corporate medical offices, Park Avenue Gastroenterology is a private, solo practice where Dr. Zaffer has been serving his patients and community for more than 30 years.

The benefits of private practice allows more personalized care, a deeper-patient doctor relationship, greater flexibility and continuity of care in treatment plans, and more attention on preventive medicine. Each of our patients is treated like family. We offer the highest quality of care in a warm and compassionate environment. 

Board-certified in Gastroenterology and nationally regarded with extensive clinical and practice experience, Dr. Zaffer provides consultation and evaluation based on the most scientifically advanced and clinically proven treatments and screenings. 

Our state-of-the-art technology and high-definition imaging and visualization of the digestive tract during colonoscopy and upper endoscopy procedures allows Dr. Zaffer to identify and accurately pinpoint subtle abnormalities, leading to a more precise diagnosis and more comprehensive treatment plan.
