Oldfields Gallery helps clients with their art and antiques as buyers, sellers, appraisers, brokers, and consultants for building collections, downsize consultation, estate liquidation, acquiring personal property insurance, making damage claims, and more. 

The nature of our work requires a combination of remote work and travel. While we collaborate with clients throughout the United States and internationally, we are physically headquartered in the southeastern United States, in Tallahassee, FL and Atlanta, GA
