Isabella Briggs plays Denise in The Summer I Turned Pretty season 3. Denise is introduced as Steven Conklin’s office co-worker and becomes part of the season’s workplace and relationship storylines.
Denise is listed as a season 3 character rather than a returning figure from the earlier seasons. Her professional connection to Steven gives the character a role in the show’s adult-transition storyline, as the younger characters move through college, jobs, relationships, and decisions about their futures.
The character appears alongside several other new or expanded season 3 roles. Sofia Bryant plays Anika, Belly’s college roommate; Lily Donoghue plays Lacie Barone, Taylor’s sorority sister; Zoé de Grand’Maison plays Agnes, Conrad’s medical-student friend; and Kristen Connolly plays Lucinda Jewel, Taylor’s mother.
Denise’s actor is sometimes mixed up with the performers playing these other newcomers because all of them were added to the final season. Isabella Briggs was announced as one of the season’s new regular cast members, while the other names listed above have different character relationships and narrative functions.
