Century 21 Real Estate has expanded its presence along Florida’s Gulf Coast through the affiliation of Sarasota-based RoseBay Realty, a brokerage with deep roots in the region and a reputation built over more than three decades. Founded in 1994 by Magdiel “Mike” Rosario after a successful aviation career, the company has grown from a locally respected operation into a prominent player serving buyers, sellers, investors, and aviation professionals relocating to Florida.
Rosario’s transition from aviation to real estate helped shape the brokerage’s identity. Drawing on relationships developed during his years in the airline industry, he built a business that became known for helping fellow aviation professionals find homes and investment opportunities across the Sunbelt. Over time, RoseBay Realty expanded beyond that niche and developed a broader presence in Sarasota’s competitive residential market while maintaining a strong emphasis on personal relationships and community service.
Today, Rosario leads the brokerage alongside Managing Broker Becky Culp, whose more than 30 years of experience in the Sarasota market has made her a trusted adviser to clients and agents alike. Together, they oversee a team of approximately 40 real estate professionals specializing in luxury homes, residential properties, vacation rentals, and investment real estate. The firm’s leadership has also signaled plans to continue recruiting experienced agents and expanding its geographic footprint along Florida’s Gulf Coast.
The decision to affiliate with Century 21 provides RoseBay Realty with access to the brand’s global referral network, marketing platform, technology resources, and international recognition. Century 21 President and CEO Mike Miedler welcomed the brokerage into the network, noting that its long-standing commitment to client service and community engagement aligns closely with the company’s values. For RoseBay Realty, the affiliation represents an opportunity to combine local expertise with the scale and connectivity of one of the world’s most recognized real estate franchises.
The timing comes as Sarasota continues to attract new residents, retirees, and investors drawn by its strong economy, coastal lifestyle, and growing housing market. The region’s population growth and ongoing business development have intensified demand for experienced real estate professionals who understand both local neighborhoods and broader market trends. Industry observers say the combination of Sarasota’s momentum and Century 21’s brand reach could position the brokerage for continued growth in the years ahead.
