Christian Siewert is currently the Michigan Chapter Liaison for Tree Fund. Tree Research and Education Endowment Fund (TREE Fund) is a 501(c)3 nonprofit dedicated to supporting scientific discovery and dissemination of new knowledge in the fields of arboriculture (the science of cultivating and managing trees in a landscape) and urban forestry. Since their inception in 2002, TREE Fund has awarded over $3.3 million in funding to support:
Scientific research on urban tree care issues
Education programs related to trees
Scholarships for students aspiring to be tree care professionals
Knowledge gained from TREE Fund research directly impacts tree care practices, arborists’ techniques and people’s lives every day. Their work is made possible by the generous support of corporate, small business and community organization partners, as well as individual donors.

Continuing Education is very important to us. We attend several conferences and workshops each year to ensure we are current on updates and safe practices in the tree care industry. This includes continuing education, learning new pruning standards, research in pest and diagnostics, and safety and professionalism. Most conferences sponsor an exhibit featuring the latest and greatest tools, materials and services also.

“We have the privilege to live and work around organisms who’s existence gives us pause…who’s existence the planet is dependent upon. This work gives us great joy.”
Our love of trees and the desire to live among them dictates that we interfere with this process. These interferences affect trees in a complex manner. Managing these interferences in the best interest of the trees and their cohabitants is my job as your arborist.
Not only do healthy trees add beauty and value to your property, but they are a necessary part of the woodland as a whole. Improper care will change how your trees interact. This will cost you as the homeowner more money in additional overhead costs and expensive future tree care from additional storm damage, cleanup and repairing the damage from improper care. Let a professional arborist explain the benefits of trees and their proper care to you.
At C & A Arborists, we aim to maintain the beauty, and health, of your trees. Located in New Buffalo, we have been servicing S.W. Michigan and N.W. Indiana for over 15 years.
Well-cared-for trees are gorgeous and beneficial, while poorly maintained trees can become significant liabilities and cost you much more in the long run..
Unhealthy trees are often either dangerous, unattractive or both. If you have a plant that needs help, trust our expert arborist to diagnose and recommend the perfect treatment for your trees and plants. Don't wait until it's too late to call our tree doctor.
C&A Arborists is the first tree service to be owned and operated by an ISA (International Society of Arboriculture) certified arborist in the Harbor Country Area. Our expert arborist, Christian Siewert, has been working in the tree service industry since 1987, and has been the owner of C&A Arborists since 1997. Christian studied arboriculture at Merristwood College in Guildford, England and received his certified arborist status from The International Society of Arboriculture after starting C & A Arborists in 1997.
Christian and his team of trained arborists know the needs of trees and are trained and equipped to provide proper care.
Pruning or removing trees, especially large trees, can be dangerous work. Tree service and tree removal should be done only by those trained and equipped to work safely in trees, which is why C&A Arborists is your trusted choice for your tree services.
