I'm sarah, and I love working with families who love the A1A as much as i do!
A Florida transplant from Atlanta, I’m the licensed Realtor behind Costiero. With a degree in Interior Design from the University of Georgia and over a decade in marketing and project management, I have a passion for real estate along A1A from Fernandina Beach to Palm Coast. With education and experience in real estate investment and flipping, my sweet spot is helping families list their piece of paradise for the best market price. I also love helping new buyers find the perfect vacation property to enjoy along our beautiful stretch of coast.
A Georgia peach at heart, I love an evening at Turner field and have attended the Masters over 25 times (yes, you read that right). My husband and I are bulldogs, but I grew up in a house divided, so I have a soft spot for that yellow jacket.
