Sarasota Brokerage Helps Fortify the Century 21 Brand Along Florida’s Gulf Coast

Current President and Broker Magdiel “Mike” Rosario originally founded the brokerage in 1994 after relocating to Sarasota following a successful career in airline management, banking, and human resources. Rosario, now nearly a 35-year real estate veteran, rose to a director-level position in the airline industry where he oversaw operations at some of the busiest airports in the country, including Los Angeles International Airport and Newark Liberty International Airport. Upon moving to Sarasota, Rosario got his start in real estate by helping pilots, flight attendants, and other aviation personnel buy and sell property in the area.

Quickly, Rosario realized his management abilities translated well to his new career, which inspired him to become a full-time real estate professional and open his own brokerage.

Joining Rosario in leadership is fellow 20-year industry veteran and Managing Broker/Owner Becky Culp. Culp has lived in Sarasota for the past three decades, which has provided her with keen market knowledge and insight into nearby luxury and second-home trends. Culp, Rosario, and their independent sales professionals also specialize in residential real estate, commercial listings, and rental properties throughout Sarasota, Bradenton, Venice, and Palmetto. Rosario, a Puerto Rican native, is also fluent in Spanish and regularly assists Spanish-speaking clients.

Now doing business as CENTURY 21 RoseBay, Rosario, Culp, and their independent sales professionals will have access to the CENTURY 21® brand’s world-class technology, marketing, lead generation, agent learning, and coaching. Looking ahead, brokerage leadership plans to continue growing its roughly 40-agent firm via strategic recruitment efforts and by exploring additional office locations in its existing market and beyond.

“Joining the CENTURY 21 brand is an exciting step forward for our company,” said Rosario. “ The strength of its internationally recognized name, innovative resources, and commitment to excellence will enhance our ability to serve clients, support our agents, and continue growing our business. We believe this collaboration positions us for a strong and successful future.”

The brokerage’s growth aspirations are rooted in the same family-oriented, people-first philosophy that has guided RoseBay since its founding over thirty years ago. By prioritizing relationships and internal collaboration, Rosario and Culp have cultivated an environment that empowers agents to succeed and provides clients with personalized, holistic service.

“Sarasota has always been a special place to call home, and that’s why I decided to plant my roots here over 30 years ago,” said Culp. “Our team takes great pride in helping buyers and sellers also discover the beauty of our community, and that shared purpose is what drives us. We’ve always been intentional about growing without losing sight of why we’re in this business, and the CENTURY 21 brand shares that same commitment to people and personalized service.”

With idyllic weather year-round and a unique blend of coastal beauty and rich culture, Sarasota is often regarded as one of Florida’s most desirable places to live. From its scenic beaches and thriving entertainment venues to its growing economy, the region is a premier destination for both full-time residents and second-home buyers.

“Mike, Becky, and their agents have spent more than 30 years carefully curating an identity defined by service, collaboration, and community involvement,” said Mike Miedler, president and CEO of Century 21 Real Estate LLC. “Over these past few decades, they’ve successfully navigated some of the industry’s most challenging and transformative periods by never losing sight of the people and communities they serve. We’re thrilled to welcome that kind of resilience and person-first mindset to the CENTURY 21 network.”
