OArborista

OArborista is a professional arboriculture company operating across the Sesimbra and Lisbon areas of Portugal. Led by Ruben Oliveira, a certified arborist trained at Broomfield Derby College in England and holding a City and Guilds NPTC certification, the company brings more than 15 years of hands-on expertise to urban and forest tree care. Specialising in urban arboriculture, OArborista offers a comprehensive range of services: selective pruning to encourage healthy growth and structural integrity; crown thinning to allow light penetration without altering a tree's overall shape; crown lifting to safely remove lower branches; sectional dismantling of medium to large trees using rope and climbing techniques; assessment and management of hazardous trees; and general landscape maintenance for gardens, parks, and institutional grounds. All work is carried out in strict compliance with health and safety standards and guided by principles of environmental balance, ethics, speed, and transparency. The team uses specialist climbing equipment and ropes, enabling safe work in confined spaces or difficult-access locations without endangering surrounding property. Beyond physical tree care, OArborista also provides environmental consultancy, advising clients on tree health, species assessment, and best arboricultural practices. The company's ethos combines technical excellence with a genuine passion for trees and the natural environment, positioning it as a trusted partner for anyone seeking responsible, expert tree management in the greater Lisbon region.
