Patient Reviews

  • "My yearly visit was yesterday, having just lost my partner of 38+ years in February my mental state was not very good. The staff and Dr. Koka expressed great care, concern and support for me during this visit as they have always done. They let me talk and cry and just listened. I have been a patient in the practice, since 2012, before Pennsylvania Cancer Specialists took over and the staff has always been very compassionate."
