philadelphia, pa • since 1964
Dimitri J. Ververelli, Inc. (DJVI) provides Mechanical, Electrical, Plumbing, and Fire Protection engineering for the buildings the Philadelphia region depends on — hospitals, universities, historic landmarks, and commercial towers alike.
Family-owned since 1964, we bring the technical depth of a large firm and the accountability of one that answers its own phone.
For over 60 years, building owners, architects, and facility managers across the Delaware Valley have turned to DJVI when a project needs more than a checklist — it needs an engineering partner who understands the building, the budget, and the people who'll use it every day. We listen first, then design systems that are efficient, code-compliant, and built to last.
