About Boulos Beshai


I was privileged to be trained by kind-hearted and expert pathologists in well-known cancer centers. Pathology has been highly rewarding to me. Behind every slide I examine, I see a patient, a family and a referring colleague, who are anxiously waiting for the "right answer." Through this, I consistently utilize my communication skills, and I always think and work in an organized and detailed manner for the patient's benefit. I believe that pathology is a continuous and endless learning process, so I happily joined this great institution to be directly involved in patient care, as well as research activities.
