I am a second-generation physician with family ties in Indiana for more than 150 years.

I spend as much time with a patient as needed to ensure all questions are answered and a treatment plan is in place.

I graduated from Case Western Reserve University and completed his fellowship training in gastroenterology and hepatology at Indiana University School of Medicine. I enjoy traveling with my wife and three daughters and spending time outdoors.

 

Clinical Interests:
  • Colorectal cancer prevention
  • Treatment of digestive diseases

“I am committed to treating each individual patient with the best quality of care and service for their unique needs.”

What to expect during a colonoscopy:

Colonoscopy expectations

A colonoscopy is a routine medical procedure that allows a doctor to examine the lining of the large intestine (colon and rectum) using a thin, flexible tube with a camera. It is commonly performed as a preventive screening for colorectal cancer or to investigate symptoms such as abdominal pain, bleeding, or changes in bowel habits. Although the preparation beforehand involves cleansing the colon and can be the most challenging part, the procedure itself is typically quick and done under sedation to ensure comfort. In this video, our Gastroenterologist Dr.Imler shares what to expect during colonoscopy and the preparations. .
