Marek is a well-rounded design professional, with comprehensive knowledge of and experience with: building envelope restoration, code compliance, construction administration, and long-term building maintenance in the Tri State Metro Area. His building envelope experience began as part of a select group of University at Buffalo students and professors working with a local manufacturer to apply cold bending complex geometries to develop prototypes of a progressive modular self-supported façade system from textured rigid sheets of metal. Marek’s fascination with building envelopes lead him to joining a young and talented team restoring a Lower East Side landmark known as the Jarmulowsky Bank Building, where he was introduced to New York City’s rigorous landmark restoration process.

Marek gradually transitioned into a project management role, where his primary focus was working with a wide range of clients to provide restoration and code compliance services.

You can often find him walking upstate NY trails or NYC sidewalks. He recently spent a week traveling between Berlin, Krakow, and Paris, and his next trips include Peru and New Zealand. During the winter months, Marek spends his time indoors exploring area museums and cultural centers.
