At Century 21 The Harrelson group, we are all about knowledge. Our agents take extensive training in marketing, working with sellers, working with buyers, and all around customer service at its best. Our website provides extensive photos and information on every community of homes for sale in the Grand Strand, and is always a work in progress. Founder Greg Harrelson spends his time studying the local market and training agents to be the best they can be for our clients.
