Dr Armstrong is an amazing doctor. he spent time with me making sure I had all my questions and concerns answered, I had a problem after surgery and he didn't hesitate to have me come in to the office to be seen by him to address the problem. there should be more doctors like him. I am completely happy with the care I received from him.

I have a high degree of confidence in Dr. Armstrong's competence and concern for his patients. He approached my follow-up with professionalism and made me feel comfortable with my progress. The PA student on his surgical rotation was also very engaged and competent.

The Dr was unable to correct my problem and suggested we wait until after my knee replacement to maybe try something else. Dr Osterling had already explained most of this to me but was trying to cover all bases to get me some relief.

This was my 1st visit w/Dr. Armstrong. I trust him completely based on personal demeanor in attending/listening to my concerns & symptoms, his analysis & explanation of a treatment plan. He is willing to put all the pieces of the puzzle together before jumping to a conclusion.

I would recommend Dr. Armstrong to anyone who needed surgery. He is a very caring, compassionate surgeon. I have recommended him in the past.

Did not receive a good description of what the surgery would be like or what the expectations were for time off from work/limitations to lifestyle following surgery. I understand it was partially because we were going to have to repeat the appointment, but it wouldn't have been bad to give that understanding at this appointment.
