Accredited companies: focus on certification as a cornerstone of their business practices, conduct their business affairs responsibly, value community and customer relations, and maintain high standards of workmanship and environmental stewardship in residential and commercial settings.

In recognition of their commitment to excellence through certification, the Accredited Landscape Horticulture Company “Seal of Approval” is awarded to successful applicants who: meet the criteria, agree to the Pledge of Excellence, and submit to a Customer Reference Verification. Maintenance of the Seal requires reaccreditation every three years to retain the accredited company status.

"Company Accreditation is simply the culmination and validation of the emphasis we have put on training development and overall professionalism of our company. It is recognition from the profession that what we believe in, and the way in which we conduct our business, is to be aspired too. For our clients, it is one of the reasons they have retained our services. It now has a name within our profession and it means that we have another item to promote and differentiate ourselves when presenting to clients. We have always believed we want to stand out and not blend in; being an Accredited Company enables us to do that." ~ Paul Doornbos CLHT, CLHM - President & CEO Thornbusch Landscaping Company Inc.
