WHO WE ARE

Founded in the heart of San Francisco, Treeline Security began in 2010 with a simple but powerful mission: provide top-tier, personalized security solutions that empower clients to take control of their safety.

Treeline Security combines the personal touch of a small, client-focused team, with the extensive reach and resources of a large network. We are a diverse, woman and minority-owned business that values relationships built on trust.

Just as a treeline exists outside the bounds of everyday danger, our team of professionals remain an unsurpassable force, at the ready.

The team handled everything from crowd management to VIP security for our special guests, making sure it all ran smoothly. They were professional, approachable, and proactive in addressing any concerns. Thanks to their expertise we were able to focus on the event itself, knowing the security was in great hands. Highly recommend!”
