How We Started

At PASS Program, founded by Dr. Francis Ihejirika, we specialize in USMLE Prep Courses and COMLEX Prep Courses. Our mission is rooted in Dr. Francis’s personal journey from a struggling student to a successful educator, inspiring us to support students facing academic challenges. We offer a personalized, empathetic approach to USMLE and COMLEX Preparation Courses, understanding the unique hurdles each student faces.

Our Unique Approach

Understanding Over Memorization
Our innovative top-down approach in our USMLE and COMLEX preparation courses focuses on understanding essential normality in medicine. This method ensures students grasp core concepts, fostering a deeper comprehension rather than relying on rote memorization. We believe in nurturing a non-judgmental and safe learning environment in our USMLE and COMLEX prep programs, where every question is an opportunity for learning and growth.

Meet Our Team

Dr. Francis Ihejirika, MD

Founder / Director of PASS Program
Dr. Francis Ihejirika, was born in a small village of Owerri, Nigeria. He emigrated to the United States at the age of eight, two years after the onset of a Civil War in Nigeria. His family was in fact the first refugee family allowed into the United States in 1969. This required new legislation from Illinois senators at that time. Francis attended Northwestern University in Evanston, Illinois, graduating with a degree in Biology. He received his medical degree from the University of Illinois College of Medicine in Champaign, Illinois.

He did his Internal Medicine and Pediatrics residency at Saint Francis Medical Center in Peoria, Illinois and enjoyed a very successful practice there for nearly 10 years. He returned to the University of Illinois College of Medicine in 1997 as a Faculty Member in the department of Pathology and became the academic support for the Urban Health Program which assisted minority students. Under his guidance, the pass rate and test scores for minority students increased significantly. He then developed, and is now current director of PASS (Physician Assisted Student Success) Program in Houston, Texas.
