Our Team



Tom VerHage - Owner
50+ Years of experience with Katerberg VerHage
Michigan State University -- Horticulture and Landscape Design

"As the seasoned veteran at Katerberg VerHage, I can honestly say we build ‘Landscapes for Life.’ Ten, 20, 30, and 40+ years after we’ve completed landscapes, they are still combining form and function and adding value to the property.  … And even more importantly, the relationships we’ve built with our customers and staff over the years is very rewarding.”

Marc VerHage
Field Supervisor / Commercial Snowplow Sales and Estimating
25+ Years of experience with Katerberg VerHage

"90% of a project's value occurs in site management, in breaking down the project and forecasting it from inception to long term maintenance. It's all the steps few people see before the finished project. At Katerberg VerHage, we do not cut corners. Our success is built on making sure landscapes function properly, that's what creates lasting value."

Leigh Johnson
Materials Purchasing / Nursery Manager
15+ Years of experience | 10+ with Katerberg VerHage

"It’s so important, now more than ever, to keep material costs to a minimum. Because we grow most of our own trees and buy in larger quantities than a lot of our competitors, we can maintain the quality you expect, and offer a great price too. We do prefer to buy locally, but some of the unique and really special things we are known for are found only on the west coast (or even further away). We love to be able to offer the best to our clients."

"Maintenance work is rewarding on so many levels – we interact with    
all kinds of clients, transforming their properties into the oasis they desire.   Whether we are overseeing spring and fall clean up, lawn care, annual and perennial gardens, seasonal and holiday-scapes, or special set ups for events; we love making our clients look really, REALLY good.”

Tim Degeest
Commercial Landscape Sales and Estimating / Project Management
20+ Years of experience | 5+ with Katerberg VerHage
Michigan State University – Associates in Turf Management
Certified Irrigation Contractor, Certified Irrigation Designer

"I grew up around the landscape industry and have always admired the way our industry puts the finishing touches on a construction project. I also enjoy watching our work mature and add beauty from one year to the next. To be involved in the transformation our industry brings to a site is one of the most rewarding careers I can think of. The combination of science, art and engineering brings about challenges on a daily basis. But along with those challenges comes the awe and wonder of seeing and working with God’s stunning creation every day. At Katerberg-VerHage, we pride ourselves in providing “landscapes for life”. I truly enjoy working with a great group of people who care about relationships with our customers and want to ensure we provide those landscapes for life."

Greg Noorman
Site Work Sales and Estimating
25+ Years of experience | 5+ with Katerberg VerHage
Grand Valley State University – BA in Management

"In our industry, site work is most often driven by the lowest bid, so it’s my job to bring value to the table.  The success of nearly every project depends on things most people never see, like grading, drain tiles, and the overall site management.  By demonstrating how our experience, thoroughness, and efficient timely communications can anticipate the full scale of a project, we save clients money, time, and ensure that potential challenges are addressed upfront.”

Jeff Stap, R.L.A. – Registered Landscape Architect
Residential and Commercial Landscape Design/Build
25+ Years of experience | 10+ with Katerberg VerHage
Michigan State University – BS in Landscape Architecture

"To design the ultimate landscape, I start by listening … and asking questions.  I find out what the client likes and doesn’t like – often reading between the lines.  Some clients may not know what they could do, so I enjoy explaining their options and teaching them about our profession. We talk about immediate goals, and possible longer term plans.  Sometimes we even have to tell them something that they have their heart set on, won’t work.  But at the end of the project, honest communications lead to satisfied customers.”
