About Us

Grand Arbor Supply (formerly Midwest Arborist Supplies) has been supporting professional arborists for over 40 years. Located in Grand Rapids, Michigan we offer prompt shipping and superior customer service from our knowledgeable staff of experienced arborists. Grand Arbor Supply is a division of Grand Arbor Group, Inc.

We started distributing Mauget micro injection products in the early 1970’s and expanded our offing to complete tree care supplies in the mid 1990’s. We proudly launched one of the industry’s first e-commerce websites in 1998 with a full line of arborist supplies. In the early 2000’s Midwest Arborist Supplies partnered with Arborjet as one of their first distributors working aggressively to assist arborists in the battle against Emerald Ash Borer. Our diverse product line covers all areas of arboricultural maintenance from climbing and rigging equipment to advanced plant health care products.

Please browse our website for all of you tree care tools, chemicals, and fertilizers. If you need further assistance or don’t see a product you’re looking for, please contact us at 800-423-3789 or info@grandarborsupply.com. We are happy to assist you to make informed decisions to help care for trees.
