USA Medical & Dental Speaker Series

The speaker series is for the benefit of college students pursuing a career in medicine or dental medicine. Medical students and dental students in our teaching fellowship program share their wisdom and experiences to help the pre-health students. In addition, the nonprofit hosts these speaker events to raise awareness for our national health project and health campaign.

Recipients of the Medical and Dental Teaching Fellowship Award receive an annual stipend to support professional activities such as research, conferences, and residency interviews. The annual stipend for each fellow ranges from $1,000 to $5,000 per year based on level of commitment.

Fellows are responsible for teaching medical or healthcare topics to train all chapter presidents at HGA and to advise student members in their journey to medical school and dental school. The nonprofit does not record these talks or distribute media.
