Andrea Antenucci, MD

Andrea "Andi" Antenucci, MD

  • Hometown: Danville, CA
  • Undergraduate: Boston College
  • Medical School: Keck School of Medicine of USC
  • Residency: UCLA
  • About Me: I was born and raised in California and absolutely love living in LA - a city that truly has it all. I enjoy exploring the LA food scene, traveling, skiing, golfing, football season (go 49ers!), and hiking to California's best alpine lakes with my Golden Retriever, Gio. When I am not in the hospital, however, I spend most of my time chasing around my adorable (and crazy!) one-year-old!
  • Why I Chose UCLA: After four amazing years training at UCLA for Anesthesiology, staying at UCLA for my Critical Care Fellowship was an easy decision. The UCLA faculty are leaders in the field, incredibly brilliant, and enthusiastic teachers. Additionally, at UCLA, I will have the opportunity to train in several high-acuity intensive care units, gain valuable exposure to patients on mechanical circulatory support, and learn from diverse multi-disciplinary teams.

Phillip Kim, MD

  • Hometown: Long Beach, CA
  • Undergraduate: University of California, Irvine
  • Medical School: Keck School of Medicine of USC
  • Residency: Harbor-UCLA
  • About Me: Having completed all of my schooling and training in southern California, I am excited to remain in the area for fellowship. In my free time, I enjoy taking advantage of the outdoor activities SoCal has to offer, including hiking, camping, and visiting the incredible national parks. I also like collecting house plants (at my peak I had 52 of them), cooking new recipes, and watching live shows.
  • Why I Chose UCLA: I chose to do critical care fellowship at UCLA for many reasons. I was drawn by the broad range of pathologies I would encounter while rotating through the multiple different ICUs, with a special focus on mechanical circulatory support. I also appreciated the department’s welcoming, supportive culture, and its reputation for clinical excellence. It was apparent that UCLA would provide me with the opportunities necessary to become a well-rounded, capable intensivist.

  • Hometown: San Diego, CA
  • Undergraduate: University of California, San Diego
  • Graduate: University of California, San Diego
  • Medical School: Keck School of Medicine of USC
  • About Me: Dr. Louis Nguyen is in his second year of his two-year fellowship after training in Emergency Medicine at Los Angeles General Medical Center. Outside of medicine, he has a diverse set of interests, including dabbling in tech, playing games, being outside backpacking, making a cup of coffee, or even learning a new hobby.
  • Why I Chose UCLA: I chose UCLA for critical care fellowship for multiple reasons. The opportunity to train across multiple high-acuity ICUs, work alongside leaders in critical care as a tight-knit team, and learning from a complex patient population were big factors. I am excited to learn a lot at UCLA and carry it forward into my future career.

Vivek Shah, MD

  • Hometown: Azusa, CA
  • Undergraduate: University of Southern California
  • Medical School: UCLA David Geffen School of Medicine
  • Residency: Harbor-UCLA Emergency Medicine
  • About Me: When not in the ER or ICU, I enjoy reading, Brazilian Jiu Jitsu, kettlebells, and cooking (not all at once).
  • Why I Chose UCLA: UCLA has been my home for medical training since I started at Geffen. It’s felt like home ever since, providing unparalleled clinical exposure with amazing faculty, co-residents, and now co-fellows. Plus, learning critical care with 365 days of sunshine seems like a winning formula.
