In my many years with Thornton Tomasetti, I have taken pride in mentoring our young architects and engineers in how a building is detailed and put together from the ground up.

With more than 50 years of experience in architectural investigation, analysis and design, Henri Gueron manages the renovation and rehabilitation of older buildings, including façades, interior surfaces and materials, and performs design for new structures. He joined Thornton Tomasetti in 1999, after leading his own architectural practice for more than 35 years. Henri is a registered architect in New York and has been an active member of the American Institute of Architects since 1974.

An Expert in Façade Investigations and Repair
Henri specializes in façade investigation and rehabilitation work. He has performed numerous FISP (formerly Local Law 11) inspections for façades in a variety of cladding materials, and is experienced in the design of repairs for deficient conditions. Henri has managed a variety of investigations, material analyses and structural distress evaluations involving reinforced concrete, steel, masonry and wood construction. His experience encompasses a range of building types, including academic, office, police stations and healthcare facilities in the New York area.

Emergency Response
Henri has provided remediation design and stabilization services for a variety of structures throughout New York City. He took part in the World Trade Center Disaster Site Recovery initiative, providing immediate damage assessment, assistance with demolition and temporary stabilization procedures and inspection of hundreds of buildings in the surrounding area.

Outside of Work
Henri was born in Paris, France, and immigrated to the United States at age 11. He is an avid golfer, and loves to cook to keep up with his wife, who is a culinary star. They have two grown sons and two granddaughters.
