I have been an Architect for over forty years and have worked with many developers and owner’s representatives. Matt is one of the most knowledgeable and professional. He is timely, responsive and resilient. He enables and inspires others, by example, to work cooperatively toward designing and building great enduring architecture.

The first tenant of 901 Broadway, an 1870 commercial building near Union Square was Lord and Taylor. When the store moved in 1914, the picturesque French Second Empire property was used for manufacturing and retail at the ground floor. After years of deterioration, this project has restored the decorative cast iron and the slate roof. The signature pavilion at the corner of 20th Street and Broadway now welcomes visitors to Brooks Brothers on the lower floors, and mixed-use residential and office space on the upper levels.
