Meet Robson De Oliveira
Robson De Oliveira is the proud founder of Tier One Electrical. With more than 25 years in the business, he has extensive experience across the industry, from residential service calls and renovations to large commercial and ground-up construction projects.
Robson started Tier One with a simple standard: every job, big or small, should be done safely, cleanly and right the first time. That standard still guides how the company quotes, plans and finishes its work today.
He leads a team of experienced electricians who share that commitment. Robson speaks five languages — English, Portuguese, Spanish, Russian and Ukrainian — so customers and crews across Massachusetts can talk through their project clearly, in the language they're most comfortable with.
