Overview
Philosophy of care | As a colorectal surgeon, I strive to provide the highest level of care while treating you with the respect and dignity that you deserve. | Why I entered medicine | In college, I volunteered at a hospital for children with special needs. While there I was able to personally see how much of a role the physicians and nurses played in the lives of the children and that feeling is what drew me toward medicine. | Community involvement | Throughout my career I have volunteered in clinics for those in homeless shelters. I have also participated in church and community health screenings and events. | Personal interests | Outside of my medical/research interests, I enjoy spending time with my family and traveling.

Philosophy of care | My patients are my family. | Why I entered medicine | I emigrated from Ukraine with my grandmother, who played a significant role in my life.

The surgeons who took care of her became forever my heroes. I vowed to do the same for those who needed my help. | Community involvement | Stroudsburg has been my home the past seven years. I look forward to having the privilege and opportunity to treat my community at Lehigh Valley Hospital−Pocono. | Personal interests | I am an avid triathlete and enjoy swimming, biking and running.
