Bullinger Tree Service
Three Generations of Serving the Bismarck-Mandan Community

In 1952, Leonard Bullinger Sr., believed there was a need for a tree trimming and removal company in the Bismarck-Mandan area and founded Bullinger Tree Service. He believed in delivering excellent customer service and superior workmanship to his customers. Through his passion and hard work, Leonard Sr. gained the trust of many home owners, and built a reputable foundation for his company.

It was not long before Leonard’s son, Leonard Bullinger Jr., was right by his father’s side learning the ropes of the family business. In 1973, Leonard Jr., began working full- time for his father’s growing business. With a strong bond between father and son, Leonard Jr., learned of course hard work, but more importantly his father instilled a philosophy of customer service and superior workmanship.

In 2003, after receiving his Bachelor of Science degree in Business Administration from the University of Mary in Bismarck, Brian Bullinger joined the company and became the third generation of Bullinger Tree Service. With a big influence from his father and grand-father, Brian is resolute in his desire to ensure Bullinger Tree Service’s future while still preserving the foundation that Leonard Sr. and Leonard Jr. worked so hard to build.

Over 60 years later, Bullinger Tree Service has grown to become the one oldest most respected tree care companies in the State of North Dakota.
