Meet the Arborist
Sidney Glenn
Head of Field Operations | Licensed 3A & 7A | ISA Certified Arborist in Oklahoma City
Hi, I’m Sidney Glenn.
I’m an ISA Certified Arborist serving Oklahoma City, with over ten years of experience in horticulture and arboriculture. I specialize in tree and shrub care, plant health care (PHC), and advanced diagnostics to uncover what’s really affecting your landscape.
My goal is simple: help you keep your trees healthy, resilient, and enjoyable; not something you constantly worry about.
A Smarter Approach to Tree Care in Oklahoma City
Tree care isn’t one-size-fits-all.
Oklahoma’s clay soils, extreme heat, drought conditions, and urban stress create challenges that most trees aren’t naturally built to handle. And more often than not, problems start below the surface, not above it.
That’s why my approach is built around three core principles:
- Prevention is better than cure
Proactive care helps avoid costly damage and long-term decline. - Healthy soil = healthy trees
Strong roots and balanced soil lead to better growth and natural resilience. - Urban trees need extra support. The urban landscape is not a natural environment. Compaction, construction, and hardscapes create stress that requires professional care.
Instead of just treating symptoms, I focus on improving the environment your trees grow in, because that’s where real, lasting results come from.
Expert Tree Diagnostics & Problem Solving
If something looks off with your tree, there’s usually more going on beneath the surface.
I specialize in identifying the why behind tree issues, including:
- Soil and root-related stress
- Environmental and site conditions
- Planting and structural problems
- Early-stage decline before it becomes severe
Many homeowners come to me asking, “What’s wrong with my tree?”
The answer is rarely simple but with the right diagnosis, it becomes manageable.
Common Tree Problems in Oklahoma City
Over the years, I’ve seen the same core issues affect trees across the metro:
- Poor planting practices
- Compacted or low-quality soil
- Drought stress and inconsistent watering
- Root damage from construction or foot traffic
These problems weaken trees over time, leading to:
- Increased pest and insect activity
- Fungal disease issues
- Thinning canopies and poor growth
The key to effective tree care isn’t just treatment, it’s fixing the root cause first.

What You Can Expect
With the right care, your trees can thrive even in Oklahoma’s tough conditions.
You’ll notice a healthier, more vigorous growth, richer color and fuller canopies, better resistance to drought, pests, and disease and increased lifespan and overall landscape value
Most importantly, your landscape becomes something you enjoy again, not something you stress over.
Tailored Recommendations—Not Guesswork
No two properties are the same, and your tree care plan shouldn’t be either.
Every recommendation I make is based on real diagnostics, specific to your soil and landscape and aligned with your long-term goals
We start with improving the environment first, then apply targeted treatments only where they’re truly needed.
That’s the difference between custom plant health care and generic, one-size-fits-all programs.
