About Jeff's Outdoor

Our Company Mission

When our company officially began in June of 1994, we had no idea the impact we could make in our landscape community, the outdoor lives of our loyal clients, and the employment opportunities we could afford our staff. We have learned and refined our skills to become a leader in our market and a proud part of our local community.

We appreciate nature.

We are healthier and happier outside. Our clients are too!

We are Professional.

Everyone we meet could be a customer.

Our Leadership Team

The Jeff's team sticks to the simple values we started with back in 1994: friendliness, hard work, honesty and integrity. Keep reading to learn about some of the people you'll be working with at Jeff's.

Jeff Ronhaar, Head Coach at Jeff's Outdoor

Jeff Ronhaar
Head Coach
Founded Jeff's in 1994

Jeff's Outdoor began when an enterprising 14-year-old decided to turn paper route customers into lawn care customers. Jeff started with one mower and never looked back. If only he had invested that money back then...

Jeff is currently passionate about overland adventures, working remotely and coaching business leaders to new heights.

Paul Dumaresq, Maintenance Division Manager at Jeff's Outdoor

Paul Dumaresq
Maintenance Division Manager
Started at Jeff's in 1999

Paul has been with Jeff's since the beginning. In fact, he's the second person Jeff hired. His main role is maintenance operations, but we have a hard time keeping Paul from getting his hands dirty.

Paul has spent years maintaining hundreds of properties and he does so with passion and with pride. Jeff likes to talk, but when Paul has a story going about his kids, no one gets a word in edgewise.

Alan Eadie, Design & Build Division Manager, Jeff's Outdoor

Alan Eadie
Design & Build Division Manager
Started at Jeff's in 2017

Alan joined our team full-time in 2017 after working independently as our landscape designer for the previous 10 years. He has an extensive background in residential landscape design and also spent years working and designing golf courses.

Alan and his wife Trish love to relax in their cabin up north; like all of our staff, the outdoors is where they feel most at home. We suspect it's that peace and tranquility that inspire Alan's best ideas.

Sherry Vildersma, Maintenance Administrator, Jeff's Outdoor

Sherry Vildersma
Maintenance Administrator
Started at Jeff's in 2011

Sherry started by running one of our Horticultural crews for years. She's now the Maintenance Administrator for Summer and Winter. Sherry and her husband Peter enjoy spending time with their grandson Noah. Touring north to cottages and camping are their favorite adventures.

She also enjoys scrapbooking, gem art, paper quilling, sewing, and building with LEGO with Peter and Noah. Sherry is fond of frogs and pieces of her collection can be seen around the office.

Tracy Ronhaar, Design & Build Administrator, Jeff's Outdoor

Tracy Ronhaar
Design & Build Administator
Started at Jeff's in 2022

Tracy has worked at Jeff's Outdoor since 2022, but honestly, being married to Jeff is probably the real full-time job. She enjoys family time and has loved becoming Grammie to her five beautiful granddaughters.

Lately, Jeff has talked her into Overlanding with their Jeep and dog Gus, and traveling to remote places across North America. When you show up at our offices, Tracy will be the smiling face that greets you at the door.
