In patients' words

"My experience at APP Gastro is the the worst I have ever had at any doctor's office. They cannot take a message accurately, send records accurately, and all the details in my chart were wrong every time I went despite me correcting them each time."

Jill Warwick Nicklaw on OpenGovNY/OpenDataNY

"As a colonoscopy patient - the experience has always been professional, caring, and knowledgeable. I have had 3 colonoscopies due to a family history of colon cancer. The prep is minor compared to the threat of cancer that I could face!"
