D&D Elevator Maintenance

Serving the greater New York region, D&D Elevator is a leading elevator maintenance company with a legacy of long-term relationships built on the highest levels of customer service.

Our principals are always easily reachable and immediately responsive to all emergency and routine needs. We strive to know all of our customers by name and place primary value on personal relationships, accountability and reliability.

Many of our current contracts are with customers that we have been serving continuously since the beginning in the early 1980s.


Established in 1981, D&D Elevator Maintenance, Inc. has been providing best maintenance practices throughout the New York metropolitan area for over 30 years.

Robert Schaeffer, currently D&D’s CEO and President, has been with the company since its inception. Robert has “worked his way up,” having performed every job description within the industry. Beginning as an apprentice, and working under two seasoned veterans (Tom Davies and Theodore Dettmering, the original owners of D&D), he learned how to install, maintain, repair and modernize elevators. In 1984, Nunzio Meccariello, currently D&D’s treasurer, began leading the effort to build an efficient and dynamic modernization and construction Department. The company was joined in 2005 by Michael Bonardi, currently D&D’s Vice President, who brought to bear his vast experience with large service, modernization and construction projects.

Over the years, D&D has achieved several industry milestones, including the first AC gearless machine installation in North America. This state-of-the-art equipment has already given the customer over 20 years of reliable operation and remains in service today. In 2001, we introduced our “Engineered Elevator Service Plan” to our Maintenance Program. This concept was based on new code requirements being adopted by the State and City of New York, complying with Section of the Code for elevators and escalators.

In 2002, Robert partnered with the National Association of Elevator Contractors to develop an industry-wide Certification program for the education and training of field technicians. This program is now being used for both training and licensing by over 80 elevator companies nationwide.

In 2003, D & D obtained approval of its “Certified Elevator Technician” (CET) program from both the Federal and State Department of Labor. D&D is currently the only merit shop Contractor in the State of New York to offer Apprenticeship training to its technicians.

In 2011, the CET program was awarded accreditation by both ANSI and ISO for meeting its standards for certification programs.
