About Me

Your digestive system is a complex arrangement of organs, muscles, chemicals and processes, spanning the length of your entire upper body. It’s imperative each internal body part functions correctly to keep you healthy.

Trust Nicholas Daane, DO, for expert care and services in gastroenterology at Avera Medical Group Gastroenterology in Sioux Falls, SD.

Expert Care in Gastroenterology

Dr. Daane offers both surgical and nonsurgical solutions for a variety of digestive conditions, such as:

  • Dyspepsia
  • Dysphagia
  • Gastrointestinal bleeding
  • Hepatobiliary disorders
  • Pancreatitis
  • Malabsorption
  • Irritable bowel syndrome
  • Motility disorders
  • Inflammatory bowel disease

Expert Care in ERCP

While Dr. Daane provides the entire scope of GI care, including colon cancer screenings, he specializes in an advanced procedure called endoscopic retrograde cholangiopancreatography (ERCP). This procedure is used to endoscopically diagnose and treat both simple and complex conditions of the liver, gallbladder and pancreas, without the need for any external incisions.

"I love ERCP because it is interesting and challenging. I am proud and excited to be able to offer this service to my community,” said Dr. Daane.

Active Lifestyle

In addition to providing excellent health care, Dr. Daane is passionate about spending time with his family and his dogs. He also loves playing video games and basketball.
