About Ben

Ben Mullen began tree-climbing in 2003. He was trained in Ireland by internationally-renowned tree-climber Bill Blythe. After completing his training Ben became head tree-climber for Noel O’Leary Tree Services and went on to open up Alpha Arbor Ltd. After 2 years working successfully in Ireland, the Alpha Arbor team moved to New Zealand and were contracted to work on some of the most challenging trees on some the most testing terrain in the world.  


Alpha Arbor Ltd. then moved to Australia in 2010 and were awarded tree surgery contracts across the state of Victoria. We also worked with other arboricultural companies and city councils on some major tree projects including Australian Mountain Ash and Mountain Grey Eucalyptus removals. During this time the team became highly specialised in working on large and dangerous trees averaging ~90m in height. We also gained experience and excelled in helicopter removals, crane work and modern rigging techniques.


Throughout our 5 years in Australia Alpha Arbor Ltd. worked alongside some of the best climbers in the world such as Joe Harris two-time Australian tree-climbing champion and Grant Cody the current Australian tree-climbing champion. We also actively participated in training apprentice tree-climbers such as Joe Loorham who went on to become one of the top contract climbers in Australia.
