 Tri-City Tree Doctor   and   United Tree Service

Our 77th Year of Providing HIGH QUALITY TREE CARE


UNITED TREE SERVICE (UTS) was established in 1946 by Marion L. Sutton.  Upon his death in 1986, the business was taken over by his son, John Sutton. For the first 20 years of its existence, the company was a full service tree company, doing all types of tree service and landscaping. In the mid-1960’s, the landscaping, tree trimming and tree removal parts of the business were discontinued. Since that time, UTS has concentrated on providing high quality tree health care, including diagnostic services and treatments for pest and disease control, fertilization, and tree surgery. 

UTS serves primarily Shiawassee, Livingston, and Genesee counties. 

Since April of 2016, UTS no longer does spraying and deep root fertilizing, but continues with diagnostic, injection, and tree surgery services. 

UTS also does deer protection applications. 

John is an ISA Certified Arborist. 

UTS maintains professional membership in the International Society of Arboriculture(ISA) and ISA Michigan.

TRI-CITY TREE DOCTOR   was established in 1999 as a branch of UTS. M. David Sutton, another son of M. L. Sutton, is the arborist who manages this branch.
Tri-City Tree Doctor serves Midland, Bay, and Saginaw counties, as well as adjacent counties in mid-Michigan and some distant counties that require specialized services. 
David has been a certified arborist for many years and became a Board Certified Master Arborist (BCMA) in 2005. As of 2022 there are only 22 BCMAs in the state of Michigan out of 784 total certified arborists. 
As of July of 2021, Certified Arborist Jonathan Getzinger has joined the company.  He hopes to soon become a BCMA.
Tri-City Tree Doctor also maintains professional membership in ISA, ISA Michigan, and the Midland and Sanford Chambers of Commerce.
