Built on accountability, consistency, and a hands-on understanding of what businesses truly need from a commercial cleaning partner.
While working in bookkeeping and accounting during her college years, Ana Liranzo noticed recurring quality control issues from the cleaning company servicing the office building. Rather than accepting inconsistent standards as “normal,” she believed commercial cleaning companies could operate with greater accountability, communication, and attention to detail.
Inspired by that experience, Ana became certified in the building services industry and founded Semper Fi Cleaning Systems, Inc. in 1997 — a name inspired by the Latin phrase meaning “always faithful.” In 2005, the company evolved into Omega Maintenance Corp, continuing its commitment to reliable service, operational support, and long-term client relationships throughout New Jersey.
Today, Omega Maintenance Corp supports offices, healthcare facilities, warehouses, laboratories, operating rooms, commercial buildings, and high-demand environments requiring specialized cleaning and facility support services.
Ana Liranzo holds a Master of Business Administration and a Bachelor of Arts in Psychology from Kean University in Union, New Jersey. Her background in psychology continues to influence the company’s client-focused approach, emphasizing communication, responsiveness, and understanding the unique operational needs of every facility.
Under her leadership, Omega Maintenance Corp has grown into a commercial cleaning and facility support company serving businesses across New Jersey with a team of more than 30 employees and plans for continued regional expansion.
Tell us about your building, operational schedule, and cleaning requirements, and our team will recommend a customized cleaning solution tailored to your facility.
Every facility has different operational challenges, traffic patterns, maintenance expectations, and cleaning requirements. A healthcare office may require detailed disinfecting and greater attention to high-touch surfaces, while warehouses and industrial environments often require specialized cleaning to help manage dust buildup, floor safety concerns, and high-traffic operational areas.
Office buildings and commercial properties also require consistent daytime appearance maintenance to support employees, tenants, and visitors throughout the day. In many environments, cleanliness impacts not only appearance, but also safety, employee experience, customer perception, and day-to-day operations.
At Omega Maintenance Corp, we customize our cleaning programs around your facility’s specific operational needs, including:

One of the company’s most memorable challenges came during the early stages of the COVID-19 pandemic, when Omega Maintenance Corp was called upon to provide fogging and disinfecting services for the Housing Authority of the City of Elizabeth across multiple locations.
At a time when uncertainty surrounding COVID-19 was at its highest, the company mobilized specialized equipment and trained personnel to provide critical disinfecting services without hesitation — reinforcing Omega Maintenance Corp’s commitment to responsiveness, safety, and operational support during high-pressure situations.
Experiences like these continue to shape the company’s approach to commercial cleaning and facility support today. Whether responding to emergency situations, supporting high-traffic facilities, or maintaining day-to-day operations, our team understands the importance of reliability, communication, and consistent execution.
We’re not a franchise—and that makes a difference.
