I’ve been in residential real estate for 10 years and started working on commercial deals about 5 years ago — and having Bernadette as a resource has been a huge part of that growth.

Whether I’m navigating a complex deal or just want a second opinion, she’s someone I know I can trust. She’s sharp, collaborative, and truly one of the best in the business.
