Red Oak Realty
Bergmark is an East Coast native who fell in love with real estate when she bought her first home in the East Bay more than two decades ago. She became an agent at a large real estate franchise, quickly moving into management. In 2007, she accepted an offer to run the local, independent Red Oak Realty. She became owner in 2010, growing Red Oak to No. 2 in marketshare. In 2019, she acquired Marvin Gardens Real Estate, adding four offices and 70 agents and staff, making Red Oak the largest independent brokerage in the East Bay with 1,000-plus transactions and $1 billion-plus in sales volume.
