History
It all began as a hobby for Alberto Tassi, rooted in his childhood love for aquariums and fish. Moving to Portugal made it hard to keep up with this passion, but when he and his wife bought a house with a small backyard, Alberto saw an opportunity. He built a small pond for the fish — a modest yet beautiful project that, over time, kept growing.
Back then, Alberto was working for a large automotive company. When a colleague asked for his help renovating an apartment, knowing his background in construction, Alberto agreed. The project's success led the colleague to suggest he start a renovation business. Alberto thanked him but admitted his true dream was to create a business focused on ponds and landscaping. Encouraged by his friend's words, "You already have the most important thing — passion. The rest will fall into place," Alberto decided to take the leap.
And so, Oásis Biosistema was born. The name was inspired by the backyard that had become his own oasis in the city. Alberto began studying ecosystems, pond filtration, and landscaping techniques, wanting to create serene oases for other people. Today, Oásis Biosistema offers a wide range of services, from ponds and conventional pools to decks, vertical gardens, and much more. "I do what I love for people who love what I do."
