2019-2020 Surgery Intern Class

The General Surgical Residency Training Program at UC Davis provides residents with unparalleled clinical and operative experiences; robust didactic, simulation and conference curricula; a team approach to career development, mentorship and fully funded research opportunities. For more than 50 years, we have been committed to training “thinking doctors” versus “cookbook doctors” and take great pride in the success of our graduates.
