Cardiovascular disease

Christopher Chen, M.D.
3rd Year Fellow - Chief 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.
Alexander Farr, M.D.
3rd Year Fellow
Undergraduate: University of Michigan, Medical School: Wayne State University School of Medicine, Residency: Baylor College of Medicine
Dr. Farr is originally from Michigan and spent most of his time there before moving for residency. He spent two years doing research in immunology before pursuing medicine as a career.
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, M.D.
3rd 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, M.D.
3rd Year Fellow - Chief Fellow

He’s since fallen in love with Portland, the PNW and amazing medical community here and looks forward to staying here beyond fellowship.
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.
