There is no publicly available rating for this care provider for one or more of the following reasons:
  1. He or she does not see patients in the outpatient clinic setting.
  2. He or she sees patients, but has not yet received the minimum number of Patient Satisfaction Reviews. To be eligible for display, we require a minimum of 40 surveys. This ensures that the rating is accurate and statistically reliable.
  3. He or she is a community provider, not a Geisinger-employed provider. Community providers tend to see patients in their own private outpatient practices, which we do not survey.

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.

Dr. Armstrong is very compassionate. He doesn't rush you if you have questions. He makes me feel comfortable in a less than comfortable situation.

Everyone was concerned about me.

When told about a new problem, we discussed how to proceed, but after leaving the office, I had many questions about the cause and degree of concern about this issue. I wish I would have asked these questions while we were talking, but at the shock of a new development I wasn't quick enough to think of this. Perhaps a better discussion of the issue could have been included with the discussion of remedy.

Dr. Armstrong is one of the most amazing doctors I've ever seen, and I've seen many, many doctors. He was kind, nonjudgmental, didn't talk down to me, and was generally just a pleasure to work with as a patient. I wish that all of the doctors that I've had to deal with were like him.

I have heard wonderful things about Dr. Armstrong. Have several friends who had surgery under his care and all have had very good experiences with him. His PA was also very nice. They both spent an extended amount of time with me, which was appreciated. I have seen Geisinger doctors for over 20 years and have only ever felt rushed out of a visit once or twice. I have many friends who have Penn State Hershey insurance and they are always complaining about doctors making them feel rushed. So the extra time is always nice.
