Rothenberg, M.D About the Experience How was your overall experience?: Option A Option B Option C Option D Option E Comments: If you want to present yourself as an ABA diplomate when speaking to the examiners, you have to know what you are talking about, how to formulate your answer quickly, and how to speak well under pressure. Dr. Rothenberg taught me all of these. He goes through the topics efficiently, practically, and provides constructive criticism. He does a fantastic boot camp review of the most common oral board cases and demonstrates true expertise. The mock exams allowed me to practice in a realistic setting and learn the key elements of presentation. Dr. Rothenberg’s course made me a confident examinee and now a better Consultant and Diplomate. A. Tzonkov, M.D.
