The National Student Leadership Conference on Medicine & Health Care is a program designed for high school students who have an interest in pursuing careers in medicine and healthcare. It aims to provide them with an immersive and educational experience to explore various aspects of the field. Since my knowledge is based on information available up until September 2021, I don't have specific details about the National Student Leadership Conference on Medicine & Health Care in 2023. I recommend visiting the official website of the National Student Leadership Conference or conducting an internet search for the most up-to-date information on dates, location, registration, and program details for the 2023 conference. The official website should provide you with comprehensive information about the event.
