Tree Care Experts - Carson Lead groundsman for Alliance Tree Care Minnesota
Carson - Lead Groundsman

One of our tree care experts is Carson. He has always had a passion for the outdoors, which started at a very young age growing up on his families farm in Stillwater, MN.  He has always been an avid outdoorsman, appreciating hunting, hiking and camping with his family. 

That strong enthusiasm for the outdoors led him to his desire to mix the outdoors with a career.  Carson shared his love for the outdoors with his love for computers, leading to his degree in 3D animation and modeling.  After his degree Carson learned that he didn’t want to be strapped to a desk and he could have both of the things he enjoyed by working outdoors by day and working indoors by night.

Our tree care expert Carson is the lead groundsman in charge of the staff, equipment maintenance, safety protocols and assisting the climbers in any way possible.  He has been with Alliance since the beginning and we wouldn’t know what to do without him and look forward to his advancement within not only the company, but within the tree industry. 

Tree care experts - Alex Gorder - Apprentice Climber/Foreman

Alex always has liked being active and outdoors.  From being in sports as a child, he developed the need to stay outside.  Whether it be camping, fishing, hunting, you name it, he loves it.  He enjoys the abilities Alliance tree work has given him, as one of their tree care experts, to boost further in the industry, as well as stay in great shape!

Alex decided to go straight into the work force after high school and became a climber.  With the help of Kelby & Melissa, there’s no limits he cannot reach.  As a young man with many choices to make in the industry, he has decided to become the BEST climber and all around tree guy that he can be! 

Alex is in charge of preparing the staff and equipment for the days work schedule, safety protocols and assisting the staff in any way possible.   He has been with Alliance for over a year and is actively working toward becoming a Certified Arborist in the coming years.

Tree care experts - Tim Morgan - certified arborist specializing in plant health care and consultations.

 Tim started to expand his love for trees and the outdoors during his full time career as a Dakota County youth corrections officer in 2002. His physical stature made it easy for him to become one with the trees as a climbing arborist. It didn’t take long before he conquered that position while working for a handful of other local tree services and went out on his own.  

Tim has worked closely with the city of St. Pauls Forestry Department board, holds multiple certifications and licenses including but not limited to his Arborist Certification and MN Pesticide License.  

One of Tim’s finer points is his thirst for knowledge and his passion for teaching. He’s helped 100s of young adults through his love for trees and he is an invaluable asset to the tree industry. Time enjoys spending his time with his two children and wife along with outdoor activities such as dirt biking, snowmobiling and traveling.

Jeff Anderson - Crane operator

Jeff started working with cranes in the oil fields in the mid 70s. To advance his knowledge and experience he began working with his brother in law in the early 80s using cranes to assist in setting trusses for new construction and moving heavy loads, machines and goods for a variety of purposes. 

His use of a cranes during storm clean up and trees allowed him to venture off and start to use cranes for technical tree removal projects. Something that the industry had never done before back in the 80s.

Jeff started using his cranes to do primarily tree removal work in 1989 and has not only been a true innovator in the use of crane work with the tree industry, but a teacher as well. Jeff enjoys spending his off time with his two children and parents while maintaining his family horse farm.

Aaron Dickinson - Arborcology Consultant

Aaron grew up in Vermont with a love of the outdoors and an appreciation for the forest & trees. After earning his Associates Degree in Urban Tree Management, he quickly found a love for plant health care. This led to his Bachelor of Science in Forest Biology, his Certified Arborist Certification, American Society of Consulting Arborist Degree and is a Registered Consulting Arborist.

Having spent the majority of his career in New England, Aaron holds a Massachusetts Arborist Certification, Connecticut Arborist License, and Rhode Island Arborist Certification. He holds pesticide licenses in Vermont, Massachusetts, Connecticut, New York, Maine and Minnesota. 

With 29 years in the industry his knowledge base and consulting experience is well known and only a handful of people hold his amount of certifications nationwide. Aaron enjoys spending his off time with his wife and being active in the outdoors.
