Senior Operations Manager/Office Manager

Martha Chapman is a licensed real estate professional in both Florida and Georgia and serves as the Senior Operations Director for ERA ONETEAM Realty and ERA Kings Bay Realty. With over 13 years of dedicated service to the organization, she plays a vital leadership role in supporting brokerage operations, agent success, and overall business growth. In addition to her operational leadership, Martha serves as the Office Manager for ERA ONETEAM Realty and as a trusted personal assistant to the broker-owners, ensuring seamless day-to-day execution across all levels of the business.
Martha brings more than 20 years of experience in face-to-face sales and customer
service, having built her foundation with a Fortune 50 retailer before transitioning into
ministry work that strengthened her passion for serving others. She joined the
company—then ERA Davis & Linn Real Estate—as an Administrative Assistant, where
her drive and commitment quickly elevated her into a key leadership position.
Throughout her tenure, Martha has been instrumental in modernizing operations,
including leading the successful transition to a paperless environment through DotLoop,
