I have recommended Dr. Mortenson to a co worker and she now goes to him. He always gives explanations , options on treatments, refers to specialist if need be and always ask if I agree with the treatment.

Duane was awesome. Explained everything I needed and was very convincing in trying to get me to agree to a colonoscopy. It seems like he genuinely cares about his patients and that they aren't just another appointment to him that he's trying to hurry out the door. I felt like my overall health meant something to him.

Duane is a prime example of all I had hoped for my physician as I age. So good at putting me at ease. His nurses are exactly the same. We are so pleased we chose St. John's Family Health.
