Why we built JMO.

Founded in 2022 and based in Malden, Massachusetts, JMO supports property management companies and REITs with recurring maintenance, MEP expertise, and broader property services.

Property teams need dependable technical service and a partner who can coordinate the work. JMO connects maintenance and repairs with turnovers, restoration, roofing, renovations, and capital improvements, so the relationship can continue as a property’s needs change.

Our mission

To be the trusted property services partner that property management companies and REITs rely on for accountable work, dependable service, and long-term support.

Our vision

To make coordinated property services easier to manage as our customers and their portfolios grow.
