Professional Activities:

I’m a vascular surgery trainee at the University of Washington. Before starting residency here, I completed general and vascular surgery training at the largest academic hospital in Latin America, where I gained experience and cared for diverse, underserved populations. In the United States, I’ve been involved in physician-sponsored IDE trials and multicenter collaborative research. My work has included data collection, database management, manuscript writing, and national presentations. I’m passionate about advancing clinical excellence, driving innovation in vascular care to expand our collective ability to improve lives.

Why UW?

I chose the University of Washington for its exceptional reputation in vascular surgery and its commitment to training surgeons through a broad and deep clinical experience. I was drawn to the program’s high case volume, exposure to complex vascular disease, and culture of excellence in both open and endovascular techniques. Beyond the technical training, I was impressed by the collegial environment, strong mentorship, and opportunities to engage in impactful research. I knew this was the place where I could challenge myself, grow, and ultimately become the kind of surgeon I aspire to be.

What advice do you have for incoming interns?

Be present, available, and curious. Show up early, stay engaged, and take every opportunity to learn—not just from the attendings, but from your co-residents, nurses, and patients. Ask questions, volunteer to help, and don’t be afraid to admit what you don’t know.

What do you like best about living in Seattle?

Seattle is an incredible place to live, especially if you enjoy staying active outdoors. I love running, swimming, biking, and playing tennis—there are countless parks, trails, and scenic routes throughout the city. One of my favorite things is catching a glimpse of Mt. Rainier on a clear day. Its presence on the horizon is always striking and serves as a powerful reminder of the natural beauty that surrounds us here. Whether it’s city views, forests, or mountain backdrops, Seattle offers the perfect mix of nature and urban life.
