What inspired you to pursue a career in your industry, and what path brought you to your current role?

My grandparents inspired me to pursue a career in architecture. One grandfather was an interior designer and one an aerospace engineer. From a young age I was always fascinated with building and construction. From drawing in school to building models, I knew architecture was the only path for me. I interned during co-op semesters in the Hamptons and landed at MSA after completing grad school. I was attracted to the firm because of the diversity of work where I could learn commercial design while integrating my residential experience.

What accomplishment or project so far in your career are you most proud of?

I am very excited and proud of two residences we are currently working on, one in Old Westbury and the other in Asharoken. The exterior design fits into the site using natural materials and unique geometry. The renderings look magical. I cannot wait till we break ground on these two incredible homes and I am grateful to be part of them.

Who has been a mentor or influential figure in your career, and what is the most valuable advice they have shared with you?

The most influential person in my career is Paul Masi of Bates Masi Architects. I first met him and learned about his work during my freshman year of college, where he completed a presentation of his ideology and recent projects. Two years later, I became an intern during my co-op semester. The most valuable advice he gave me was when beginning a project, strip it down to the basics and only add elements when necessary. Simplicity is key.

What trends or opportunities do you see shaping the future of your industry?

The most relevant trend that we utilize every day is AI. From enhancing renderings to back-of-office spread sheets, it is critical to be on the cutting edge as the technology grows.
