About

I bring a strong focus on innovation and practical problem-solving to existing buildings and building envelope design at Thornton Tomasetti, using advanced technology to deliver high-impact solutions.

As a Building Envelope Engineer at Thornton Tomasetti, I focus on the assessment, design, and renewal of building envelope systems. My work includes detailed field investigations, development of practical strategies to improve energy performance, and support for compliance with the Massachusetts Stretch Energy Code.

I have contributed to projects involving façade restoration, historic preservation, thermal performance upgrades, and moisture management. My experience includes work on educational, research, and civic facilities.

Guided by Thornton Tomasetti’s values of integrity, collaboration, and sustainability, I am committed to improving the performance and longevity of the built environment.
