Callie Harris serves as Senior Real Estate Agent with The Donnelly Advisory Group, working closely alongside Brenda Donnelly in the representation of luxury properties throughout Old Town and the Lower Florida Keys. Her practice is distinguished by a deep understanding of waterfront ownership, coastal environments, and the lifestyle considerations unique to island living.
A full-time resident of the Keys since 2005, Callie brings firsthand knowledge of neighborhood character, boating access, marine conditions, and the regulatory nuances that influence waterfront real estate. She is particularly valued by clients seeking guidance on coastal homes, live-aboard suitability, dockage considerations, and environmentally sensitive properties.
Prior to her career in real estate, Callie spent more than 15 years in marine science education and conservation, working with respected organizations including The Turtle Hospital, Reef Relief, and MOTE Marine Laboratory. She holds a degree in wildlife studies and a U.S. Coast Guard 100-Ton Captain’s License — credentials that provide clients with rare, practical insight into the maritime aspects of property ownership in the Keys.
Callie’s approach is calm, analytical, and detail driven. She is known for helping clients understand not only the property itself, but the broader coastal environment, regulatory framework, and lifestyle alignment that inform long-term value and enjoyment.
Working in partnership with Brenda, Callie provides highly personalized, informed experience for buyers and sellers seeking exceptional representation in Old Town and the waterfront communities of Key West.
