Doc seemed extremely rushed and wanted to pass off other doc as soon as appt started.. didnt think i had any injuries even after checking me and wanted to order tests; although tests were in my record indicating the injuries i had and he still felt they were inaccurate and would not resolve anything.... was not pleased

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.

Dr. Armstrong is a real good guy that I trust with my surgical care. His title should be exceptional surgeon rather than general surgeon!
