Welcome to your practice for coloproctology

Our coloproctological specialist practice has been in operation for over 20 years. It was founded by Dr. Angelika Hartjen and is now run by Dr. Klaus-Peter Ullrich, Dr. Gabriela Popovich and Dr. Sandra Kowalsky.
We treat conditions of the colon, rectum, pelvic floor and anal sphincter. We offer thorough advice on patients’ problems and their medical condition.

The treatment includes an anal ultrasound scan and a test of anal sphincter function. Our therapeutic options range from conservative treatments to smaller outpatient operations as well as inpatient treatments. Furthermore, our team offers holistic medical care for the entire gastrointestinal tract like colonoscopy and gastroscopy in a friendly and respectful atmosphere.

Your practice team warmly welcomes you!
