About
Meet Ethan Collier
Founder of Collier Landscaping & Irrigation, and the person who's on-site for your project — not just in the office.
My Story
Nine years, hundreds of projects, one focus
Designing and building beautiful landscapes is my passion. I started working in the landscaping industry at 17, and over the years since I've had the privilege of working on hundreds of projects across the San Diego area — from small irrigation fixes to full backyard transformations.
That hands-on experience is where I built a deep, practical understanding of residential landscape design and construction. I became a licensed contractor and built Collier Landscaping & Irrigation into a full-service design-build company — one that handles a project from first sketch through final walkthrough, not just one piece of it.
I'm still the one showing up to your property, whether that's for a design consultation or the day the crew breaks ground. That's on purpose.
