Board-eligible physicians in any primary discipline of medicine are encouraged to apply. A Colorado medical license (full or in-training) and current DEA certification are also required.

Applicants who cannot meet these requirements, such as international fellows, may be able to participate in the International (non-ACGME) track (see the International Fellows & Rotations section).
