Depends in how you define 'creationist.' I do "believe in one God, the Father, the Almighty, maker of Heaven and Earth, of all things visible and invisible." I do not, however, interpret the book of Genesis literally and believe that the agency of that creation conforms to the sequence of events discovered after the fact using scientific observation.
Any story that is written down is necessarily incomplete and must function as much or more on a metaphoric level then on a physical recapitulation of EVERYTHING that happened in the time of that story.
