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.

I chose internal medicine because it allows me to establish long-term relationships with my patients. I truly enjoy the follow-up care and ongoing relationships I have with my patients, welcoming back the same patients again and again. It is my goal to help manage all of your health care needs - promoting healthy lifestyles, managing chronic conditions, treating illness and coordinating the transition between specialists, hospitals, and other caregivers.

I understand the importance of communication in the current health care environment, and will strive to keep you and your family informed every step of the way.

Philosophy of care | I believe in a patient-centered approach to medicine. That means treating my patients as individuals and really focusing on their personal preferences, values, cultural traditions and lifestyle choices. It also means giving them the tools they need—as individuals—to take care of themselves. The old way of medicine – when people see a doctor once they’re already sick – is clearly not working. Today’s approach focuses on prevention, and I am passionate about spreading the message. The goal is to get people into the doctor’s office early, before problems begin. Then, we can work as a team to create the healthiest future possible. I strongly believe in the 'patient-centered medical home' concept. | Why I entered medicine | I always envisioned helping other people and making a difference. When I did my clinical rotations, I knew I would end up in internal medicine. I feel this is where I can have the greatest effect on people’s lives. I can spend time getting to know my patients while providing a lifetime of care. | Personal interests | I started running when I was in medical school, and I haven’t stopped since. I like that the only thing you need is a pair of sneakers. You can do it anywhere, anytime. Once my feet hit the ground, I can focus on the motion of running without any other thoughts racing through my head. It’s my stress relief, and it really works for me. I’ve run several 5K and 10K races. I just completed my second half-marathon, and I hope to do a full marathon in the future.
