He was recently elected to serve on the American Medical Association’s Board of Trustees for a two-year term.
Dr. Armstrong has fostered an interest in ophthalmic telemedicine and healthcare technology innovation and entrepreneurship since medical school. He is focusing his research endeavors on instituting tele-ophthalmology at Mass Eye and Ear and beyond. He has served as an advisor for various health technology startups. In his role as founder of Ocular Technologies, he has been working with collaborators in Boston and across the United States in the design of novel telemedicine and artificial intelligence technologies in the field of ophthalmology for which he won the 2020 MIT 100k Entrepreneurship Award.
Dr. Armstrong has published more than 16 peer-reviewed publications, multiple book chapters, and presented research and lectures at multiple national and international conferences. Dr. Armstrong’s clinical research in ophthalmology has focused on novel ophthalmic multimodal imaging techniques for a variety of eye diseases, as well as epidemiologic studies of eye trauma presenting to emergency departments across the United States.

The Doctor was very nice and pleasant he was seeing patients because my Dr is on maternity leave. That office takes a long time to finally see the Doctor the wait is just way to long. The only bad thing was the horrible music being played in the waiting room completely inappropriate for a Doctor's office. It was 80s club and Rock music. Several people were not happy about it including me. It was like torture as you are already not happy about the LONG WAIT.

The office was having some issues with the phone lines being down and could not receive calls for a couple of days. The reception area was especially sensative to everyone for this issue. They handled each complaint with tact and were as courteous as possible to everyone affected. They managed to rotate the patients in an orderly manner and made issues almost seamless in the process. That allowed the rest of the staff to provide services without huge wait times. The process from getting pre-examined to having images taken was just as smooth and the nurses were just as efficient and sensitive to all of us.
