Endoscopy Centers

We are proud to offer two specialized endoscopy centers in Wausau and Stevens Point. Equipped with the latest technology, our centers provide a comfortable environment for endoscopic procedures. Our experienced GI professionals deliver high-quality care, ensuring your peace of mind throughout the process.

Provided Services


Radiofrequency ablation is a therapy primarily used to treat Barrett's Esophagus, a precancerous condition in the lower part of the esophagus. By using heat, we can destroy precancerous tissue before it becomes cancerous. This therapy is performed through the oral cavity, similar to a standard upper endoscopy.

Breath Hydrogen Test

The Breath Hydrogen Test measures the amount of hydrogen in an exhaled breath which can indicate problems in the small intestine. This test is particularly helpful for patients with symptoms such as abdominal pain, bloating, distention, diarrhea, or increased gas. It aids in the diagnosis of conditions like sugar intolerance, rapid intestinal food transit, or small intestinal bacterial overgrowth (SIBO).

Capsule Endoscopy

Capsule endoscopy involves swallowing a small capsule with a built-in camera, roughly the size of a large vitamin pill. As the capsule naturally passes through your digestive system, it takes pictures of your intestine. After approximately eight hours, you return to our office where we remove the monitoring device used to record the images. Our expert providers review the imaging from within your small intestine and contact you with the results. The disposable capsule exits naturally in your bowel movement.


Our gastroenterologists undergo extensive training to perform colonoscopies. We also arrange any necessary diagnostic tests and further treatments. Unlike other facilities that solely perform colonoscopies, we offer comprehensive care. Gastroenterologists conduct more colonoscopies and remove more precancerous polyps than any other providers, ensuring you receive the highest level of qualified care.

Endoscopic Ultrasound (EUS)

EUS involves using an ultrasound attached to a scope to obtain precise imaging of internal organs, including the esophagus, stomach, liver, pancreas, and rectum. It provides detailed images of lesions seen during standard endoscopies or other imaging studies like CT scans or MRIs. During EUS, tissue samples can be taken for valuable diagnostic information.

Endoscopic Retrograde Cholangiopancreatography (ERCP)

ERCP is a procedure used to diagnose and treat conditions in the pancreas, gallbladder, and liver. Our providers use an endoscope passed through the oral cavity to access the tubing that drains these organs. With this approach, our doctors can investigate the organs, perform biopsies, capture images, or expand narrowed areas if necessary.

Esophageal Manometry

Esophageal Manometry is a test that measures the pressure and pattern of muscle contractions in the esophagus. By passing a thin tube lined with sensors through your nose, down the esophagus, and into your stomach, we can collect measurements. This test is particularly useful for patients with unexplained difficulty swallowing.

Fecal Transplant

Fecal transplant is used to treat persistent Clostridium difficile (C. diff) infections. In partnership with Open Biome, we obtain purified fecal material and introduce it into the patient's gastrointestinal tract. This procedure adds healthy bacteria to the recipient's colon, overwhelming and eliminating damaging bacteria.

Flexible Sigmoidoscopy

When performed by a trained gastroenterologist, sigmoidoscopy examines the lower part of the colon. The procedure typically takes a few minutes and can be done without anesthetic or sedation if desired.

Hemorrhoidal Banding

Using the CRH O'Regan System, we provide gentle suction to grasp hemorrhoid tissue located just inside the anus. Then, a rubber band is placed around the tissue to restrict blood flow. This causes the hemorrhoid to shrink, dry up, and fall off. Typically, one to three sessions can completely eradicate worrisome hemorrhoidal tissue.

Infusion Services

Our infusion center offers a range of intravenous therapies, including rehydration with normal saline, iron supplementation for anemia, and immunosuppressant infusions for the treatment of Crohn's disease or ulcerative colitis. Our dedicated team of nurses provides these services in a friendly, relaxed outpatient setting at our Wausau and Stevens Point offices.

Liver Elastography

Liver elastography with FibroScan® is a non-invasive method to measure the stiffness of your liver. It involves emitting a small pulse of energy, which may feel like a slight vibration, onto your skin. FibroScan® calculates the speed of this energy to provide your healthcare provider with an immediate measure of liver stiffness. Increased stiffness could indicate inflammation or scarring, crucial information for addressing liver health.

pH Studies

pH monitoring involves attaching a small capsule or probe in the lower portion of your esophagus to continuously measure and record acidity levels for approximately 48 hours. Elevated measurements suggest acid reflux. You wear a small pager-like device to collect this information while keeping a symptom journal. After 48 hours, you return the recorder to our office for evaluation by one of our expert gastroenterologists.

Upper Endoscopy

An upper endoscopy is a procedure where a scope with a built-in camera is inserted through your mouth to examine your esophagus, stomach, and the first part of your small intestine. The procedure is performed under mild anesthesia. Upper endoscopy allows for the evaluation of various gastrointestinal ailments, including acid reflux, difficulty swallowing, nausea, bleeding, and abdominal pain.
