As a family man and father of three, Dr. Wientzen feels blessed by the great range of specialty care and medical testing services which are just minutes away from his home.

Ease of access to advanced medical tests is important to Dr. Wientzen, his own family and the hundreds of Northeast Iowa families who choose the Gundersen Decorah Clinic for their care. It means peace of mind, and savings in time and expense, for him, for Gundersen Decorah Clinic patients and the community.
In fact, the range of testings available right at the Decorah Clinic may amaze you: Dr. Wientzen says hardly a day goes by when he doesn't hear a patient's surprise.

"Let's say a patient needs a CT scan," explains Dr. Wientzen. "They almost always, say 'Oh, so we need to go to the hospital?' We tell them they can do it all right here and they say, 'That's awesome!'"

Gundersen Decorah Clinic has its own medical testing lab, too. With labs and advanced imaging technology also on site, and mobile technologies that come regularly to the clinic, a patient typically need travel no farther than down the hallway at the Gundersen Decorah Clinic. This includes, but is not limited to:

  • Full cardiac stress testing
  • Nuclear medicine testing
  • Bone density imaging
  • MRI
  • CT (CAT) scanning
  • X-ray
  • Audiology testing
  • Ultrasound
  • Concussion baseline and post-injury testing
  • Labs including fasting cholesterol, blood sugar, liver and kidney function, vitamin D, Calcium and other typical panels ordered by your provider.

"If you come for a visit and need labs and testing, we can do almost everything here in this building," says Dr. Wientzen. "We can provide everything a patient needs with rare exception—at the same time or in short order."

He notes that along with convenience of advanced testing, 20-plus visiting Gundersen Health System specialists provide a big advantage to patients of the area.

"It makes such a huge difference to have specialists and testing available right in Decorah," he says. "Our goal is to provide as many services as we possibly can here, where you are comfortable and close to home."
