Patient Comments (3)
in Quakertown, PA |
I was scoped by Dr. Marcos in 2014 as a family member told me they were diagnosed with the hereditary condition known as Barrett's esophagus. Not only was I diagnosed as having Barrett's, remarkably, Dr. Marcos also identified a considerable lesion on my small intestine. Fortunately the lesion was not cancerous, but would have become cancerous within 1-2 years. Dr. Marcos referred me doctors to deal with the condition. I was operated on, the lesion was removed, and I am fully recovered!

Dr. Markos is a very kind and caring doctor. He takes the time to get to know his patients and listens to all concerns. He is really thorough and does a great job explaining his thoughts and next steps. One of the only doctors I have seen who sits you down in his office to chat after your exam.
