How It Began
The COAST Story
Luxury real estate markets rarely change overnight. More often they evolve through a small group of leaders who recognize opportunity before the broader industry does. On Hilton Head Island, that shift began several years ago when two of the market’s top-producing agents — Rick Saba and Tristan O’Grady — made a decision that would reshape not only their businesses but the trajectory of luxury real estate in the region.
At the time, both agents were already operating at the highest tier of the profession, each surpassing 100 transactions and more than $100 million in career sales volume. Their reputations were built on trust, performance, and the ability to represent exceptional properties and clients.
Rather than remain inside a traditional brokerage model, they chose eXp Realty for the creative freedom and global reach the platform offered. From that vision, COAST brokered by eXp Realty was born.

Rapid Growth
From Four Agents to One Hundred
What began as an ambitious idea quickly became one of the most compelling growth stories within eXp Realty. COAST started with just four people — two co-founders, a Director of Operations, and a listing coordinator. Within two years, COAST became the #1 eXp team in South Carolina by sales volume.
Today the organization includes over 100 Realtors and has helped launch six additional eXp teams, expanding its influence beyond Hilton Head Island. Agents were drawn to the team’s collaborative culture, entrepreneurial mindset, and luxury-focused marketing approach.
The speed of this growth reflects something deeper than recruitment — it reflects a model that works. Systems that scale. Culture that retains. And results that attract.
