Dr. Najeeb is the single most spectacular medical teacher you will ever have! I love this man. He has clarified everything from the coagulation cascade, immunology, neurology, and embryology. His sense of humor and brilliant illustrations make everything stick well in your memory. His ability to illustrate 3-dimensional relationships has been useful for excelling in anatomy. I cannot thank you enough for all the wonderful work you do. I recommend your lectures to anyone who wants to truly understand medicine!
