I was told to keep this appointment but he can’t do anything for me until I have the breathing test that are scheduled for October 24. I felt very disappointed about not having my issue addressed. I didn’t feel it was his fault.

As I said previously, Dr. Westerhausen is very professional and compassionate provides patient care on today’s normal standards. He never made me feel like he was in a rush, he answered all of my questions he listened. He explained things in great detail for my current health challenges and future outlook and the need for follow up and images.

08/26/2026

He was very thorough with explaining the symptoms and showing them to me on his monitor, the procedure to be performed and what to expect post procedure! That was very reassuring to myself and my wife.

I really liked Dr Westerhausen and his nurse was wonderful

11/26/2025

He seemed to be curt/contrite with me.Boldly saying that I didn't have COPD.Without giving any other possible reasons why i cough so much. And have shortness of breath.Making it seemed like my pcp shouldn't have even wasted his time on sending me to him!And just to have my pcp do a test every year!That I don't need a pulmonologist!He didn't offer a clue as to why/what is wrong with my lungs!!!!!!I wouldn't tell anyone that I know to see him!!!!

11/24/2025

Did great

I came in for a second opinion and chose to change from my previous pulmonologist to Dr. Wesenhousen. I could not be happier!
