Biography
Medical School: Medical University of South Carolina
Residency: Mayo Clinic
Why Children's National: I was excited to join Children's National Hospital because of its status as a high-volume program with a diverse patient population. I was drawn to the combination of experiences offered at both Children’s National and George Washington University Hospital, where I could manage complex referrals and ECMO at a Level IV center, as well as being a part of delivery room resuscitations in a Level III setting. Living in D.C. is a major bonus too!
Research Interest: Neurodevelopmental outcomes
Fun Fact: Before medicine, I worked as an English teacher in France.

Residency: NYU/Bellevue Hospitals
Why Children's National: The unique combination of an amazing Level IV NICU/referral center with exposure to a wide range of pathologies/diverse patient population and a Level III NICU with delivery experience seemed perfect for fellowship training. I was also excited about the research opportunities with the Developing Brain Institute. I have found the culture here to prioritize our learning as fellows in a dynamic and engaging way!

Biography
Residency: Baylor/Texas Children's Hospital
Medical school: Meharry Medical College
Why Children's National: I was excited to come to Children’s National to gain more experience at both a referral and delivery center knowing that would enhance my abilities as a clinician, especially to be well trained at one of the top institutions and supported by some of the best people in the field! Also coming back home to D.C. to be close to family, living and working in a diverse area and getting to serve this population was really important to me! I love the culture both in and out of the hospital, not to mention being a HUGE foodie, D.C. is such a great place to be!
Research Interest: Point-of-care ultrasound (POCUS)
Fun Fact: I love to travel and try new places; I have lived in five major cities and counting.

Biography
Medical School: University of Pennsylvania
Residency: Icahn School of Medicine/Mount Sinai
Why Children's National: I was excited to come to a large referral center for the most complex and unique pathology, balanced with time at a Level III focused on learning the fundamentals of prematurity. Equally as important, I felt that the faculty and co-fellows were warm and supportive, and I have been proven correct. Our class is already close one month in, and we constantly comment on how lucky we feel to have each other. Lastly, I went to undergrad in D.C. and absolutely love this city: its architecture, its museums, its nature, and its food scene! Almost half of us lived in D.C. prior and came back, which bodes well!
Research Interest: POCUS for NEC
Fun Fact: Many of our pets have food-related names here, so adding my cat Babka to that list. Otherwise, outside of work you can find me enjoying grandmother-like activities (crochet, book club, last person this century with an AMC Stubs membership).

Biography
Medical School: University of Virginia
Residency: Cincinnati Children’s Hospital
Why Children’s National: From my residency, I knew I liked the setup of a large Level IV NICU being separate from the Level III NICU. This lets you get exposed to numerous interesting cases with complex physiology without the risk of being interrupted by deliveries. Having these two separate environments helped me feel like I could better focus on my learning in both settings. I also knew I wanted to expand my skills in fetal care consults and difficult conversations so being at a center that managed referral patients, post-op patients, and ECMO patients was important to me. My wife and I also had our first baby during residency so being close to family in the Northern Virginia area was also important.
Research Interest: Palliative medicine and fetal care
Fun Fact: I started painting by following along with Bob Ross and now most of the paintings in my house were painted by me.

Biography
Medical School: University of Pennsylvania
Residency: Children’s Hospital of Philadelphia
Why Children’s: I loved that Children’s National is a big referral center where I’m exposed to high acuity and a wide variety of diseases, but also that we rotate at GW where we do delivery room resuscitation and manage more bread-and-butter NICU patients. I also wanted to gain ECMO experience and wanted to go somewhere where EMCO is managed in the NICU. Plus, I went to college in D.C. and was very excited to come back to this incredible city.
Research Interest: Clinical research and quality improvement
Fun Fact: I have a fluffy corgi named Strawberry, who I occasionally carry around in a backpack.

Medical School: SUNY Upstate
Residency: Eastern Virginia Medical School/Kings Daughters
Why Children’s: Children’s National stood out to me as a place where I could have the autonomy I needed for consistent "boots on the ground" learning, but also as a place full of friendly and supportive people. The vast pathologies at Children's National, in addition to the delivery opportunities at GW, seemed like the perfect training for a budding neonatologist.
Research Interest: Neonatal nutrition and education
Fun Fact: In my freshman year of college, I learned how to row and competed at the NCAA Rowing Championships.
