Hi, I’m Jeffery Stevenson of JSI Landscaping.

First off, thanks a lot for taking the time to find out more about what my company and I have to offer.

I’ve been landscaping in the Greater Portland Metropolitan area for over 25 years now and built this company from the ground up. We have a stellar reputation around town, having thrived for more than two decades on referrals alone, and have won numerous design awards and awards of excellence for both expertise and service.

I am an internationally accredited Certified Landscape Professional with PLANET, as well as a Certified Landscape Manager (also with PLANET), and hold a National certification as a Certified Landscape Irrigation Auditor. I’m also licensed with the Landscape Contractors Board in all phases of landscape construction and a licensed Landscape Irrigation Backflow Device Installer.

My professional affiliations and memberships include the Oregon Association of Nurseries (OAN), Oregon Landscape Contractors Association (OLCA), PLANET (Professional Landcare Network), and the Association of Northwest Landscape Designers (ANLD).

As far as formal education goes, I received a Bachelor of Science in Business from Oregon State University and studied Landscape Technology at Portland Community College.

When you work with JSI Landscapes, your project is never passed off to someone who doesn’t know what they’re doing. I offer personalized service, meaning you will be working directly with me and my crew – a small handful of my best guys have been working with me for a decade or more.

We live for landscaping. We love working with the Earth and finding the best ways to combine Nature’s beauty with Man’s standards to create an exquisite embrace of form and function.

Are you ready to let us dig our hands in and bring out your yard’s potential – to bring your dream alive? If so, just get in touch using the info on our contact page; we’ll set you up with a free consultation.

I look forward to getting to know you more!

Kind Regards,


Have a Perfect Day

What Perfect Means Is Up To You
