About Us

Welcome to our practice. Our doctors have each received advanced training in a particular sub-specialty. In the case of our practice, these are gastroenterology (diseases and disorders of the digestive system) and diseases of the liver and pancreas.

Gastroenterological and liver specialists focus on the care and treatment of digestive diseases and disorders that include polyps, cancers, bleeding ulcers, cirrhosis, hepatitis, and other problems of the gastrointestinal tract and liver.

Doctors Karp, Hernandez and ​Beniquez Nieves are board certified and specialize in diseases of the esophagus, stomach, intestines, colon, pancreas, liver and biliary tract / gallbladder. They can provide you with screening colonoscopies for colon cancer and are dedicated to providing high-quality care to our patients.

Medicare and most insurance policies are accepted.
