About us

Our company co-founders, Paul and Ioannis (John) Zannis, are both Mechanical and Electrical engineering graduates of National Technical University of Athens and also hold postgraduate degrees (M.S. and Ph.D.). They first started working on MEP design and supervision projects in 1974. In 1987 they co-founded P-I Zannis and Associates, a company that became one of the leading companies in Greece in MEP consulting and design, offering a wide range of services.

The current company Managing Director, Michael Zannis, a Mechanical Engineer with B.Sc. and M.Sc. degrees from Yale University (Connecticut, USA), constitutes the next generation, tasked to guide the company in an era of increasing economic and enviromental challenges.


In the past years our company has completed more than 250 projects, most of them in Greece, but also in neighboring countries in Eastern Europe, Northern Africa and the Middle East.

Project Map

The diversity of our past projects, both in scale - from relatively small to some of the largest and more important in the region - but also in variation - ranging from road tunnels to hospitals and everything in between - has equipped us with the experience and adaptability which enables us to tackle all kinds of MEP projects.

More specific, our past projects include:

  1. Buildings of all types, such as hospitals, hotels and casinos, commercial buildings, theaters and museums, educational buildings, residential projects, transportation terminals, and many more.
  2. Infrastructure Projects, related to transportation, such as roads and road tunnels, railways (conventional and underground) and airport servicing facilities, and also city utility networks, such as city water supply and sewerage networks, and electrical distribution grids.
