about our team

Bill Hernandez and Bryan Sereny are co-founders of the Bill & Bryan Team, Douglas Elliman’s #1 team in Miami Beach for the past ten consecutive years and consistently ranked among the top .1% producers nationwide by annual sales volume. Together they have generated over $3 billion in sales over two decades, with individual transactions reaching over $100 million.

Bill and Bryan are recognized leaders in the South Florida luxury market, advising buyers and sellers of waterfront estates, luxury condominiums, and trophy properties across Miami-Dade, Broward, and Palm Beach counties. Their clients include business leaders, Forbes 100 Billionaires list members, Fortune 500 executives, hedge fund and private equity principals, and upper-high-net-worth international buyers establishing residences in Florida. While some of these acquisitions were publicly reported as part of deliberate relocations to Florida and broader domicile and tax strategies, a significant portion of their business is conducted privately and off market, consistent with the discretion their clients value.

Beyond sales volume, what distinguishes the Bill & Bryan Team within South Florida luxury market is the depth of their market intelligence. For more than 21 consecutive years, the team has tracked and analyzed luxury market data across the region on a monthly basis, building a long-term perspective few brokers can match. Together, Bill and Bryan have closed sales in more than 175 buildings and neighborhoods, memorized the floor plans of over 300 developments, and represent more transactions exceeding $5,000 per square foot than any broker partnership in Florida.

Their market knowledge has consistently helped establish new pricing benchmarks across Miami Beach's most coveted neighborhoods. They achieved a record-breaking $3,300 per square foot on Pine Tree Drive, forecast years before the market arrived there. They also set the South of Fifth price per square foot record at Continuum South Beach, hold the price per square foot record in Sunny Isles, and were selected to represent Witkoff’s Shore Club Private Collection, which produced the highest-priced condominium sale in Florida history at over $110 million.

Bill and Bryan operate with one guiding principle: their clients’ long-term interests always take precedence over the broker's short-term incentives. They have advised sellers to decline offers they believed undervalued a property, counseled buyers away from overvalued acquisitions, and have consistently been proven right over time. It is the foundation of a referral-based practice built entirely on trust, verified results, and over two decades of compounding market knowledge.
