ads ENGINEERS was founded in 1979 by Michael Ambrosino, PE and Dominick DePinto, PE, specializing in Mechanical and Plumbing Engineering.  In 1982, they were joined by  Kenneth L. Schmieder, PE and expanded the range of expertise to a full MEP Engineering Firm

ads ENGINEERS offers full consulting Engineering Services (HVAC, Electrical, Plumbing, Fire Protection, Energy Modeling, LEED Services and Commissioning).

As an owner-operated mid-size firm, ads ENGINEERS is able to offer the depth of a large firm, while still providing the “hands-on” involvement of the firm’s partners. The partners, with their commitment to advancing the MEP industry through lectures and published papers, are the driving force behind ads ENGINEERS.  Our staff are seasoned professionals, committed to providing quality services, and to working as team players to meet fast track deadlines. They are dedicated to improving coordination among the mechanical and architectural trades, enhancing quality control, and focusing upon cost effective solutions.

Our firm has active projects throughout the United States.  At ads ENGINEERS, cooperation, innovation and practical solutions have consistently resulted in repeat commissions from existing clients with whom we have developed extremely successful working relationships.


Corporate Philosophy

It takes a team of individuals, not companies, to make a successful project. At ads ENGINEERS the partners and employees are committed to giving their personal attention and service to our clients.
