Our Founder
Andrea Ferreira, the heart behind Harmony Professional Services LLC, was born in Brazil and has proudly called New York City home for more than two decades. Her journey from Brazil to Manhattan shaped her resilience, work ethic, and deep appreciation for the spaces where people live and work. With a vision to blend professionalism with genuine care, Andrea founded Harmony to bring a new standard of consistency, trust, and excellence to commercial cleaning in the city she now calls home.
Under her leadership, Harmony has grown into a team of experienced professionals, each with more than 10 years of expertise, united by the same values of dedication and detail. Andrea believes that a clean space is not just about appearance, it is about creating harmony, focus, and pride for the people who use it every day.
