Industry Partners
To ensure we spend our time focusing on our specialty of diagnosis and preservation, Sims leaves the pruning and removals to the experts that we trust. Although Sims cannot guarantee the work of other companies, anybody on our recommendation list is someone we have worked with and have been approved by the arborists of Sims THS. Trimmer referrals are not listed in any particular order.
TO OUR FELLOW GREEN INDUSTRY PEERS: Have we worked with you before? Are you interested in being put on our referral list? Send us an e-mail!
