Gretchen has been the keeper (and policer) of the Nicholson brand for more than eight years. Outside of brand policing, she makes sure the rest of the world knows how amazing our team is and how awesome our work is by putting us front and center in industry publications, at conferences and everywhere in between—and she will never be convinced that silty sand and sandy silt aren't the same thing.
