Your specialist for tree care and tree removal

In the mid 1980’s Gary Blackburn founded Westerwälder Baumdienst (Westerwald Tree Service) which through its success quickly grew into the nationwide active Baumdienst Siebengebirge (Seven Mountains Tree Service).

Having a solid foundation based on training and years of experience, for example in the famous Sherwood Forest, Gary Blackburn provides the best credentials. In addition are his years of study at the renowned Merrist Wood College in Surrey.

Baumdienst SIebengebirge was quick to earn a reputation for competence and reliability, which today still grows through the addition of further staff and the opening of new offices. Baumdienst Siebegebirge serves customers in Nordrhein-Westfalen, Rheinland-Pfalz, the Koblenz area and Cologne, Bonn, Düsseldorf and the Eifel. Many of the customers are local councils, nature protection organisations, forestry commissions, companies, parishes and private households.

Approximately 20 trained specialists service the customers with small to large scale contracts from tree care to difficult tree removal including stump removal.

The family business is run by Gary Blackburn together with the involved and highly competent support from his sons Kevin and Alexander, both of which as trained tree inspectors, tree surgeons and European Treeworkers manage their own tree teams. Gary’s third son Luke is already in the third year of his training and enthusiastically supports his brothers.
