About Me

My name is Dr. Sarmen Sarkissian.  After completing my residency in internal medicine at LAC+USC I would go on to complete my fellowship in hematology/oncology at UC Irvine’s Chao Family Comprehensive Cancer Center.  During my last year of fellowship, as I was developing a study plan for both board exams, I would write my very first and very own clinical vignette. Over the course of several years, this would evolve into HOQBank.com with more than 2,500 clinical vignettes, 7,500 flashcards and 450 diagrams.  Ever since its launch in 2019, it has remained a valuable asset for our community, helping 100s of fellows and practicing hematologists/oncologists pass their board exams.  All questions have been written by me, as have all the flashcards.  I have enjoyed the feedback to date and will continue to grow it, offering more content and resources with time.
