Philosophy of care | My job is to save the lives of patients with aortic aneurysms, to prevent strokes in patients with carotid artery disease and to avert amputation in patients with impaired blood flow to their extremities. However, what I treasure in my job is the relationship with patients and their families, developed sometimes over years and sometimes quickly during a challenging time in their lives. I always remember that patients like you who seek out my expertise are people – with jobs, lives, hobbies, families and compelling personal stories. I enjoy hearing those stories and playing a role in caring for those individuals. | Why I entered medicine | Honestly, I wasn't very good at physics. After studying physics and engineering as an undergraduate at Haverford College and as a graduate student at the University of Virginia, I figured out somewhat serendipitously that I was good at surgery and enjoyed caring for patients. Vascular surgery is intellectually engrossing and technically challenging. | Community involvement | My wife Oksana and I support the YMCA, and three generations of Jacksons have attended a YMCA summer camp in Rhode Island. Because Oksana is of Ukrainian heritage, we support a number of humanitarian causes in that country. | Personal interests | My family and I enjoy hiking and camping (Indian Garden Campground at the Grand Canyon is my favorite campsite). My kids play a lot of soccer, and some baseball and softball, so I've become a student of those games. We're pretty dedicated Philadelphia Union fans.
