At Windermere International Realty, we believe real estate is about more than buying or selling a property. It’s about understanding our clients, knowing the market, and being there every step of the way.

Ron Biegelaar, Broker, brings years of real estate experience and a hands-on approach to every transaction. With a strong knowledge of the Windermere, Winter Garden, Dr. Phillips, Bay Hill, and greater Orlando markets, Ron focuses on providing straightforward advice, personal attention, and a smooth experience from start to finish.

Working alongside Ron is a team of experienced real estate professionals, including Hans Welbergen, Broker Associate, Marilyn Welbergen, Sales Associate, and Brenda Gooch-Vanderpol, Sales Associate. Each brings their own experience, knowledge, and personality to the team, while sharing the same commitment to personal service and putting clients first.

Hans brings a practical approach and strong understanding of the local market, helping clients confidently navigate their real estate decisions. Marilyn is known for her attention to detail, communication, and personal approach throughout the buying and selling process. Brenda brings her own experience and dedication to helping clients achieve their real estate goals, with a focus on making every transaction as smooth and straightforward as possible.

Together, Ron, Hans, Marilyn, and Brenda offer the personal attention of a local team, backed by the strength and reputation of Windermere International Realty.
