Trenton Sandler

LSU Division I distance runner and running YouTuber

Dennis first named Trenton in his piece about finishing an Ironman 70.3 in Coeur d’Alene with zero training. That race was a test of operating principles rather than preparation, and Trenton was part of the post-race reality. The two shared Korean BBQ with a group of young builders, a moment that marked a shift toward a healthier starting line for Dennis. Trenton is an LSU Division I distance runner who also runs a YouTube channel focused on running, and his personal site was built by Dennis’s team.

Trenton appears in Dennis’s broader context of building with people who are doing the work publicly. When Dennis watches Trenton build in public alongside Grant, he sees a dynamic that resonates with his own history. Specifically, Dennis recalls his late friend Chris Rummel. Chris died in a motorcycle accident in Mountain View, leaving behind undocumented work that was locked behind his credentials. That loss is a primary reason Dennis builds in public now. Seeing Trenton and Grant execute this approach makes Dennis feel he is witnessing what he and Chris had, but done smarter. It is a recognition of a shared value: transparency and presence over hidden effort.

Trenton is one of the first sixty names on Dennis’s People & pets list, a ranking system Dennis uses to select the individuals he honors on this site. He is also listed among the names on the Money Tree page, which tracks the people Dennis works with and believes in. This inclusion signifies that Trenton is not just a contact, but a builder whose work and presence matter to Dennis’s ongoing projects.

Dennis takes pictures with people so he can remember them, and this page serves as the public version of that habit. The specific photos from their time together live in a named Google Photos cluster. Dennis intends to come back to narrate those frames, providing the context behind the images that capture their interactions.
