What factors made Northwestern stand out to you when choosing a residency program?
I rotated at Northwestern as a visiting sub-I student and loved it. The breadth of cases and complexity of the pathology was appealing and has not disappointed. The surgical training is phenomenal, the faculty are approachable and dedicated, and the resources for research and career development are unmatched.
What areas of vascular surgery are you most interested in exploring or pursuing as a career?
I'm passionate about caring for patients with peripheral artery disease and carotid disease, and much of my research has focused on how to improve our education of patients with PAD. I really enjoy the problem-solving and creativity that is required of treating patients with aortic diseases, include aneurysms and dissection. I'm also interested in multidisciplinary surgical care and enjoy working with other surgical specialties to manage complex pathologies.
How would you describe the culture of the program and the overall resident experience?
Our culture is supportive and inclusive. My coresidents are some of my best friends and I'm incredibly grateful to get to train with them. We work hard, but we also frequent Timmy O'Toole's after education and have a competitive fantasy football league. Our advanced practice providers, our program administrators, and our OR nurses are all phenomenal and make our training possible. We're incredibly lucky!
What do you enjoy most about living in Chicago, both inside and outside of the residency?
Chicago is an awesome city! I try to jump in Lake Michigan as much as I can, and I love spending time at the concrete beach in the summer. It's a great place for foodies and music-lovers - there's always a new restaurant to try or a concert to attend. Running along the River Walk or Lakeshore Trail is also unbeatable.

What factors made Northwestern stand out to you when choosing a residency program?
I primarily chose Northwestern for the people. The trainees were hard working and supported each other, led by faculty that bend over backwards for their patients and their trainees. It didn't hurt that it's located in a pretty awesome city.
What areas of vascular surgery are you most interested in exploring or pursuing as a career?
I fell in love with vascular surgery for the variety, big and small cases, open and minimally invasive, everywhere in the body so I'm hoping my career reflects such a variety.
How would you describe the culture of the program and the overall resident experience?
I can call any of the vascular trainees or attendings at any time for any reason. We choose to spend a lot of time with each other in and outside of the hospital.
What do you enjoy most about living in Chicago, both inside and outside of the residency?
The food, the people, and the lake.

- Graduate School: Federal University of Minas Gerais (UFMG)
- Undergraduate: Federal University of Minas Gerais (UFMG)

What factors made Northwestern stand out to you when choosing a residency program?
I chose Northwestern because of its unique combination of tradition and innovation. Northwestern is one of the most established vascular surgery programs in the country, with a history of landmark contributions to the field and more than 50 years of training vascular surgeons who have gone on to become leaders in our specialty.
At the same time, our program is forward-thinking and embraces cutting-edge vascular technologies, with a strong emphasis on teamwork, quality improvement, and patient-centered care. Our faculty are exceptional mentors, and of course, the Code Aorta program is another.
What areas of vascular surgery are you most interested in exploring or pursuing as a career?
My primary clinical interests are complex aortic disease and peripheral artery disease, with a particular interest in endovascular and hybrid approaches. From a research perspective, I am interested in outcomes research and quality improvement initiatives aimed at improving results for patients undergoing peripheral revascularization and AAA repair. I am also passionate about international collaboration.
How would you describe the culture of the program and the overall resident experience?
The people make our program special. There is a true sense of camaraderie among residents and fellows, and my co-residents and APPs have become true friends. The atmosphere is highly collaborative, with a strong focus on teamwork. We are consistently supported by our attendings, outstanding APPs, and program coordinator, all of whom are deeply invested in our education and professional development.
What do you enjoy most about living in Chicago, both inside and outside of the residency?
Chicago is a lively, multicultural city with incredible architecture and an amazing lakefront. I love how much there is to do and explore.

Chong (CJ) Na, MD
- Medical School: University of Miami Miller School of Medicine
- Undergraduate: University of Florida

What factors made Northwestern stand out to you when choosing a residency program?
Northwestern draws a referral population complex enough that you're not waiting until your last year to be part of difficult cases, and the integrated track means you build that exposure early on. I was also drawn by the Midwest, and Chicago specifically. I wanted to train somewhere that felt like a place I could actually live in during residency, with a city around the hospital and people who were pleasant to work with.
What areas of vascular surgery are you most interested in exploring or pursuing as a career?
All of it honestly. I joined this field because the breadth is the appeal — open aortic work, endovascular, limb salvage, access, venous disease, etc. — and I haven't found a reason to narrow that down. If a subspecialty interest emerges in the latter half of my training, great, but I do not feel the need to force it.
How would you describe the culture of the program and the overall resident experience?
The structure of Northwestern surgery is set in a way you constantly learn from other divisions, not just your own — abdominal transplant, critical care, plastics, cardiac, thoracic surgery, etc. Each brings a different way of thinking about sick patients and/or how to operate; being exposed to these high-volume subspecialties here have shaped how I manage patients more than a single mentor alone. The cross-pollination is what I value most about the resident experience at Northwestern; you leave with more than just a vascular surgery toolkit.
What do you enjoy most about living in Chicago, both inside and outside of the residency?
Living in Streeterville means my commute to work is a walk, which matters more than you would think when you're rounding early or operating late. Outside of the hospital, the lakefront is right there — the path, Lake Michigan in the summers, and the whole downtown within reach on-foot or train ride. Chicago is a big city without the cost or the hassle of the coasts, and each neighborhood is distinct enough that you can spend the entirety of residency and still find new parts of it. It's an easy place to have a life outside of residency.

What factors made Northwestern stand out to you when choosing a residency program?
Northwestern stood out to me as a residency program because of the people. After doing a sub-internship here, it was clear to me that the residents, fellows, APP's, and faculty all worked together as a team with the ultimate goal being excellent patient care, teaching and supporting one another along the way. Each faculty member brings a different point of view of not only the specialty, but also of different career trajectories that the trainees have the opportunity to look up to and emulate.
What areas of vascular surgery are you most interested in exploring or pursuing as a career?
I am most interested in pursuing the biomedical engineering world of vascular surgery through device development and innovative surgical techniques and tools. Vascular surgery as a field has a unique intersection between new technology and hands-on surgery that is always changing and improving.
How would you describe the culture of the program and the overall resident experience?
I would describe the culture of our program as "work hard, sweet treats later." As a group, we are hard-working and supportive, making sure that we do whatever it takes to take the best care of our patients as possible. When the day is over, we celebrate together with snacks, always!
What do you enjoy most about living in Chicago, both inside and outside of the residency?
There is never a dull moment in Chicago - there is always a new restaurant to try, lakefront to walk/bike along, museum to wander, and shopping to do. I love that we are in the middle of the best city and get to have the best of both worlds of training and living experience.

My primary interests are in complex aortic disease, endovascular device design, and advanced imaging techniques such as 4D Flow MRI.
How would you describe the culture of the program and the overall resident experience?
There is a shared motivation to become the best vascular surgeons that we can be. We love to learn from each other and have a great time while we're doing so. While vascular residency/fellowship is certainly busy, we always find time to get together along with our partners/spouses/families - whether it be after education/journal club, on the weekends, or just because!
What do you enjoy most about living in Chicago, both inside and outside of the residency?
Living in Chicago makes it really easy to be spontaneous for dining, sports, arts, and entertainment. It's an accessible city with multiple modes of transportation keeping you connected to all the neighborhoods, nationally, and even internationally (although O'Hare will make you question your sanity at times). The summers here are unbeatable and definitely make you forget how cold the winters are.

What stood out most to me was not only the culture of our program but the entire division. I had the privilege of doing a sub-i and spending research time here as a student, and I could see how invested the faculty were in trainees, how much the residents supported one another, and how much people genuinely seemed to enjoy working together. I also knew I wanted a program that would give me excellent clinical training in a strong health ecosystem while still encouraging me to pursue my interests in research, education, advocacy, and leadership.
What areas of vascular surgery are you most interested in exploring or pursuing as a career?
One of the things that initially drew me to vascular surgery was how broad the field is, so I am still excited to explore a lot of it! I am interested in limb salvage, aortic disease, and the pathophysiology underlying these disease processes. I’m excited to learn more about vascular remodeling and further delve into how we can better predict outcomes and design therapies.
How would you describe the culture of the program and the overall resident experience?
I’d describe our program as a tight-knit family! Everyone is very hard-working and approachable, and I always feel so supported by my peers, seniors, staff and our faculty!
What do you enjoy most about living in Chicago, both inside and outside of the residency?
Growing up, I always loved visiting Chicago- it’s one of my favorite cities! My favorite thing is how easy it is to walk along and enjoy both the lakefront and the river. Living in Chicago makes it so convenient to (even spontaneously) take advantage of time outside of the hospital since there’s always something exciting to do!
