CLINT LANDON

President & Owner

I am a native to the Northwest, born and raised in the Portland Metropolitan area. I have worked in the green industry for the last 25 years in areas ranging from landscape maintenance and construction, climbing arborist, plant health care technician, arboricultural consultant, sales representative and now as President and owner of General Tree Service.

I earned a Degree in Horticulture from Oregon State University. I am a Board-Certified Master Arborist and have a Tree Risk Assessment Qualification.
When not working, I enjoy spending time with my wife Amy, children Grace and Cooper and my dogs Silvi and Arlo exploring the outdoors. I look forward to meeting you soon and helping you with your tree and landscape needs.

STEVE ZETTERLUND

Operations Manager

I have been with General Tree Service since 1992. I am an ISA certified arborist and licensed with the state of Oregon as a Landscape Construction Professional.

I am also a licensed commercial pesticide applicator and pesticide consultant. I have a Bachelor of Science degree in Biology from North Park University in Chicago, IL.

I love spending my time outdoors. I especially enjoy hiking and exploring the beauty of the Pacific Northwest. I love the Oregon coast and any trail that leads to a waterfall! I also enjoy taking road trips and exploring out of the way locations.

JIM SHERWOOD

Commercial accounts & Wilsonville rep

I grew up in Eastern Washington spending my summers working on a wheat farm from high school all the way through college. I have a bachelor’s degree in Forestry/Geography from Eastern Washington University and Washington State University with a minor in Biology.
I have been involved in urban forestry for over 30 years and have been working for General Tree Service for over 27 years. I am an ISA certified arborist and am a licensed commercial pesticide applicator and consultant through the Oregon Department of Agriculture.
I enjoy fishing, hunting, golf and bowling but my biggest passion is competitive gardening and particularly, growing giant pumpkins. I have grown a personal best 1,868 lb. pumpkin and am ranked amongst the top 10 growers in the world.
I am a board member of the Great Pumpkin Commonwealth which oversees the competitive weighing of thousands of giant fruits and vegetables throughout the world. I am also a founder of the Pacific Giant Vegetable Growers, a Northwest group of competitive gardening fanatics! I welcome the opportunity to meet and work with you to help you care for your trees and landscapes throughout your home and business.

KYLE FORDHAM

Area Representative Manager

I entered the tree care industry in 2005 after a severe windstorm rolled through my home state of Minnesota. In 2010, I moved to Portland to climb the beautiful trees of the Pacific Northwest.
After 15 years of swinging around in trees, I’m happy to put my passion and experience to work as the newest area representative at General Tree Service.

I graduated from Portland State University with a degree in philosophy and a certification in social entrepreneurship with studies focusing in behavioral economics, systems science, social innovation, and design thinking.

When I’m not immersed in the world of arboriculture, I’m busy with music, cycling, billiards tournaments, woodworking, leather working and spending time with my wife. I also volunteer on the board of directors for Robin’s Reach, a non-profit focused on community education and effectiveness monitoring for wetland restoration projects in the Portland metro area.

Juan Rodarte

McMinnville rep

Juan started working in the tree care industry in 2009 after moving to Oregon to work with his brother. The shift in scenery from the deserts of Nevada to the forests of the Pacific Northwest deepened his love and respect for the lush green landscapes and the variety of trees found in his new home. As an arborist, he’s done just about everything but finds his passion in beautifying properties with his fine-tuned ornamental pruning skills. When he’s not busy at work Juan likes to fill his days spending time with his family and playing guitar in his band.

ANDREA CRACKNELL

Customer Service

I have always loved spending time outdoors, both for work and play. I started in the green industry in high school and continued through college, working summer jobs with landscape crews, small nurseries, and for private landscapes. I continued to nurture my love of plants and earned a degree in Horticulture from Oregon State University.

I began with General Tree Service in 1999, and spent many years working in Plant Health Care department, primarily as the Turf technician. I really enjoyed getting to know our GTS customers while working to improve and maintain their landscapes. In recent years, I have transitioned into Customer Service, and taking on other office roles.

In my free time, I’m usually at a ball field or basketball court, cheering on our two teenage daughters. When we can pull away from sports, my husband and I enjoy taking the kids camping and exploring some of our great National Parks.

ANGELA O’DELL

Accounting Clerk

I was born and raised in small town Oklahoma and am a diehard Sooners fan. I moved to the Portland area in 1995 and began my career with General Tree Service in 2001. I spent my first 16 years with GTS as a customer service representative and then moved into accounting in 2017.

In my spare time I enjoy spending time with my husband and son, snuggling with our dog Pearl (the Director of Barketing for General Tree), watching sports (especially college football), cooking and serving in our church.

IRIS REIMNITZ

Landscape Design/Customer Service

I was born and raised on Kodiak Island, Alaska spending much of my childhood outdoors and on my father’s fishing boat. I graduated from the University of Washington with a B.A. in Germanics and earned a teaching certificate there as well.
After 8 years as an elementary teacher, I moved to the Portland area. Soon thereafter, I began summer work as assistant to the head gardener for Washington Park and the Pittock Mansion. It was there I discovered my true passion in life. I have now worked with people, plants, and trees for the last 21 years.
My specialty lies in landscape design and consultations, planting projects, designing outdoor containers, and full on landscape renovations. I am also an ISA certified arborist and can assist with tree preservation as well as all aspects of our customers’ landscape needs.

In my free time, I savor time away from work with my family and our two dogs. We enjoy our beautiful outdoors with hikes in the gorge, camping on high alpine lakes, and summer days on the coast.

DEBBIE GARDNER

Office Manager

I’ve lived in Oregon all my life and love all its green beauty. Before joining General Tree Service in 2001, I spent several years working in the “corporate world”. After the birth of my son, I knew I had to get out of it and find a career with more of a balance between home life and work life. I have found that here.

I started in Customer Service and shortly after transitioned into Human Resources and Office Manager. I have met a lot of great people here over the years and felt like a valued part of the company.

When not at work I enjoy spending time working in my yard, walking my dog and floating down the Clackamas River.

Emily Horvath

Customer Service

I was born and raised in the Bay Area of California and moved to the Pacific Northwest in 2013 to start my own life adventures. Though there are days where I miss the California rays, I could never give up the beauty of Oregon. I had never worked in the green industry prior to joining General Tree Service in 2019 BUT! I have been in customer service for 10 plus years. I have worked in retail and healthcare, collecting the proverbial badges of experience in the customer care field and finally found a home here with GTS. Moving from the “corporate world” to a family business has been one of the best decisions and experiences. Everyday I learn more about plants, trees and things with leaves while getting the opportunity to work with our passionate staff and wonderful customers.

I savor time away from work with my partner in crime Jonathan and our cat Booker. Spending our days immersed in board games, good books, cooking, laughing, crafting and adventuring around Oregon from its bustling charming cities to its magnificent forests.

Call in anytime! I am here to schedule appointments, help with billing concerns, be a point of contact or if you want to just say a quick “hello”…
