What are your future plans? Academic interventional cardiology or electrophysiology
Why did you choose OHSU for your fellowship? After spending time in the bay at UCSF for residency, the opportunity to return back to Portland for fellowship was an opportunity I could not pass up. The cardiology fellowship has achieved an exceptional amount of progress in the last several years, as has the department as a whole. I found the subspecialties of interventional cardiology as well as electrophysiology, where my interest lie, to be exceptionally strong. Both groups have great clinical volume, exceptional clinical and personal mentorship, and an abundance of opportunities to get involved to whatever extent you wish. People across the division are extremely kind, invested in your learning, and a joy to work with.

Chris Chen

Christopher Chen, M.D.
2nd Year Fellow

Undergraduate: Texas A&M University, Medical School: Texas A&M Health Science Center College of Medicine, Residency: Baylor College of Medicine

Dr. Chen is a Houston native and his initial interest in medicine and then cardiology was sparked from a prior job as a nurse assistant and telemetry tech during his undergraduate years. He left the great state of Texas to escape the heat/hurricanes, explore a different area of the USA, and learn from a new crop of physician educators.

What are your future plans? Pursuing a career in EP or Imaging in an academic or private setting.
Why did you choose OHSU for your fellowship? Comprehensive program (they pretty much have everything). I was particularly drawn to EP and Imaging. Two major hospital systems/population - a private/academic-hybrid University Hospital and the good ol' VA hospital both connected by a wonderful sky bridge overseeing the Willamette River and the city of Portland with Mount Hood in the background. Balanced clinical duties - while the fellowship has its months of heavy clinical duties the call schedule is extremely reasonable (we are not one of those programs where your first year is trial by fire) and spread more uniformly throughout 3 years. Faculty here are very supportive; I was surprised that the culture here is NOT to avoid calling your attending in the middle of the night when things are going south and you need the extra support. Our program director really cares for us and has shown in the past that she will go the extra mile in creating opportunities to customize and mold your training goals to fit your career goals.
What do you enjoy doing outside of training? Taking my eighty-pound cream retriever named Casper to a whole multitude of amazing dog parks around town, and hanging with my co-fellows and all their dogs too! Also, enjoy sports and Netflix.

Interests: Interventional cardiology
Why did you choose OHSU for your fellowship? Because of the people that I meant on my interview day. There is a tremendous amount of support for pursuing all fields of cardiology. Everyone here is part of one big family and is committed to seeing you succeed. OHSU is also a large referral center for the area, so the cardiac pathology is very diverse, which I think is important for training.

What advice do you have for residents applying to fellowships? Think about programs where you will fit in with the people and the culture. It is by far the most important consideration for picking a program.

Khoa Nguyen

Khoa Nguyen, M.D.
2nd Year Fellow

Undergraduate: University of Michigan, Medical School: Virginia Commonwealth University, Residency: University of California - Irvine

Dr. Nguyen did a chief year prior to the fellowship. It was a valuable year to slow down and reflect on the different career pathways available to young physicians. For example, he says one day, I might have been attending on the wards; another day I was running a didactic lesson for medical students; and on a different day, I was serving as a liaison between hospital administration and house staff. By dawning these different hats, the chief role propelled him into different situations and tested his responses to them; therefore, divulging many valuable “ah-hah” moments.  The year came with highs and lows as expected, but it was a phenomenal experience.

What are your future plans? I want to spend the first year of my fellowship to delve into and learn about the various fields within cardiology and proceed from there. I can see myself practicing in an academic setting in the future.
Why did you choose OHSU for your fellowship? Diverse clinical experiences, renown teachers with emphasis on understanding integrative physiology, and a supportive environment.

Francis Phan

Francis Phan, M.D.
2nd Year Fellow

Undergraduate: Wichita State University, Medical School: University of Kansas School of Medicine, Residency: Oregon Health & Science University

What do you enjoy doing outside of training? hikes with his fiancee and 90 lb goofy rescue pup, working out, cooking, college basketball, KC Chiefs and rooftop beers in the PNW summers.
Why did you choose OHSU for your fellowship? As a former OHSU resident, I was fortunate to experience first hand how collegial and supportive the faculty and fellows are towards one another. I knew that this was a foundation for me to thrive in and I feel incredibly grateful to train here.

Following medical school, he completed a research year at Mayo Clinic, Rochester evaluating into surgical outcomes of patients with valvular heart disease. Completing residency in Portland at OHSU was not only an enriching academic experience, but he really loved living in the beautiful PNW, spending as much time as possible outdoors checking out new hiking trails and trying out all the great vegetarian food in Portland with his sister and friends. During residency he became involved in research related to cardiac amyloidosis and subsequently completed a fellowship in cardiac amyloidosis here at OHSU. He is excited to stay in Portland where he has made so many great friends and can’t wait to learn all that he can during his general cardiology fellowship training here at OHSU.

What are your future plans? I plan to pursue a general cardiology fellowship next year.
Why did you choose OHSU for your fellowship training? OHSU had very supportive, approachable faculty who were focused on helping me learn and achieve my goals. Having spent 3 years as a resident at OHSU I felt confident that I would have a great clinical experience focused on education as well as required resources to help support my research endeavors.
What do you enjoy doing outside of training? I love spending as much time as I can outdoors usually hiking, camping, or skiing. When I'm not outdoors I enjoy watching/playing soccer and spending time with my friends.
