With 40 years of experience in high-end residential and commercial ground-up construction, my work encompasses more than $50 million in completed projects across some of the most sought-after addresses in New York and New England. My career has been driven by a lifelong passion for design, craftsmanship, and building high-performance homes that stand the test of time. I take pride in combining efficiency, innovation, and attention to detail to create homes that are as durable as they are beautiful. Outside of work, I’m an avid sailor and skier—both pursuits that reflect my appreciation for precision, challenge, and the satisfaction of mastering every element I work with.
