Pop-Pop is Dawn and Jeff's maternal grandfather and Sharon Spier's father. His wife is Granny Porter.


Prior to the series he was in army; he would write letters to his wife while in basic training.

He has lived in Stoneybrook his whole life and currently still lives there at 747 Betrand Drive. Pop-Pop was a banker who is now retired. He is an organized person and had an office he frequently used in the finished basement.

Mary Anne mentions that even though she has not known Granny and Pop-Pop very long, they treat her like a granddaughter and she thinks of them as grandparents.

In Mary Anne and the Music Box Secret, he and his wife went on an anniversary cruise, and their basement flooded while they were gone. A neighbor watching the house informed Sharon Spier of the flood, and she got to work right away in order to fix it before they returned from vacation. She called a plumber and got members of the BSC to help clean it up. When he and his wife returned they were relieved to see that the damage wasn't as bad as they thought and was mostly fixed by the time they got home. Before Sharon and the BSC began the clean-up, Mary Anne mentions that Pop-Pop was proud of how he fixed or made everything in the basement, rather than hire someone else to do it. He converted the rec room into a cozy space, built some of the shelves and cabinets, and set up a workshop in the corner.

His best friends are Esther and Hank. Granny and Hank grew up in the same neighborhood.


  • When he was 11, he wrote a prize-winning essay on what it means to be an American. In Mary Anne and the Music Box Secret, Sharon finds the essay among many of his and Granny's papers.
