Here are some highlights of our program, which we feel set us apart:

1. Los Angeles General Medical Center: Our residents are exposed to a variety of practice settings. We spend most of our time at Los Angeles General Medical Center, one of the busiest hospitals in the US, in one of the most diverse counties in the US. Here we have the privilege of caring for the underserved, and learning from a wide range of pathologies.

2. Other Practice Settings: In addition to LA General, we rotate at Keck Hospital of USC, which exposes us to subspecialized surgical pathology and the handling of complex cancer resection specimens. Our program is also associated with Children’s Hospital of Los Angeles, where we spend time learning pediatric anatomic pathology, apheresis and blood banking, and cytogenetics. Last, but not least, we share a campus with the Los Angeles County Office of the Medical Examiner, which provides top notch training in forensic pathology.

3. Unique Experiences: Pathologists can see patients, and at our program we do! On our cytopathology rotations we staff a Fine Needle Aspiration Clinic, where we perform superficial aspirations with and without ultrasound guidance, and subsequently interpret them. We also see patients during rapid on-site evaluations in cytopathology, on our 2-week apheresis rotation at CHLA, and on our microbiology rotation where we spend a week rounding with our colleagues in infectious diseases.

4. Teaching Opportunities: We are closely associated with the Keck School of Medicine of USC and frequently have medical student rotators in our department. Additionally, we have regular opportunities to lead small group sessions in pathology at the medical school.

5. Research & Mentorship: Our esteemed faculty are leaders in their respective fields and offer mentorship and guidance to our residents as we navigate residency training. Many faculty are actively involved in research and book writing and provide ample opportunities for residents to participate. Our residents and faculty attend and present at a variety of conferences throughout the year including USCAP, CAP, and LASOP among others.

6. Location: Our program's location in the vibrant city of Los Angeles provides residents with a unique cultural experience and a wealth of extracurricular activities. It’s not often that you can live in a place with 284 days of sunshine and the ability to ski and go to the beach in one day!

7. Our Residents, Fellows & Faculty: We may be biased, but we think we get to work alongside some of the coolest, nicest, smartest, and best people around. You will form career-long (and lifelong) relationships during residency.
