About Marina

Real estate is personal.
So is the way she works.

Marina Sirbu came to South Florida by way of Romania and Moscow, and brought with her something that's increasingly rare in this business: patience. She doesn't push, she listens. She doesn't rush, she investigates. And by the time you sign — whether you're buying a $480k starter or a $5M penthouse — you understand exactly what you're signing for.

Over seven years at London Foster, she's closed 142 transactions across Miami Beach, Sunny Isles, Bal Harbour, and the Brickell waterfront. Her clients are doctors, founders, retirees relocating from New York, and international families putting their first roots down in Florida. She speaks fluent English, Romanian, and Russian — and is conversational in Spanish — which means a lot of her business now comes from referrals through embassies and family offices.

What sets her apart isn't the volume. It's the retention. 67% of her closings in the last two years came from past-client referrals. That's not a metric she markets. It's just how she works.

Client Reviews

What clients say

Marina handled the sale of our Sunny Isles condo from start to close in 41 days — for $90k over asking. She was honest about what we'd get, ruthless on the negotiation, and made the whole thing feel effortless. We've already referred her to two friends.

Daniel & Elena R. Sunny Isles · Sold 2026

We relocated from Moscow with our two kids and Marina found us a home in Bal Harbour we'd have never discovered ourselves. She handled the school district questions, the inspector, the lender — even the moving company. World-class.
