We are a fourth-generation family with a passion for creating lasting value.
The Bainum legacy began in 1936 with the arrival of Stewart Bainum, Sr., in Washington D.C. Over the next seven decades, he and his son, Stewart, Jr., built industry leaders in hospitality and healthcare, creating jobs and substantial value.
White Oak Enterprises now manages the family’s diversified portfolio of assets and serves their private charitable endeavors. This ensures the Bainum legacy extends beyond financial success, fostering positive social impact for generations.
Our Story
From a determined entrepreneur treading new waters to a dynamic, professional investment office.
17-year-old Stewart Bainum hitchhikes from Cincinnati to Washington, D.C., with $3 in his pocket. Crossing the Arlington Memorial Bridge on foot, he senses opportunity.

Stewart and Jane Goyne marry in 1941 and eventually have four children: Barbara, Stewart, Jr., Roberta, and Bruce. Stewart progresses from being a plumber’s helper to a licensed plumber to a contractor who renovates homes to sell while residing with his family in the basement.

Stewart forms Realty Investment Company, the initial development company and family office, in 1951. Six years later he builds his first hotel, the Park Silver, in Silver Spring, Maryland, and three years after that he opens his first retirement community with his brother, Robert.
Stewart merges his Park Consolidated Motels into Quality Courts Motels, forming the company that will later become Choice Hotels International, one of the world’s largest hotel companies.
Stewart and Jane form the Bainum Family Foundation (originally The College Foundation) to guide their family’s philanthropic efforts.
Both the healthcare organization (operating as Manor Care) and the hospitality operation (operating as Quality Courts Motels) issue stock to the public.
Stewart Bainum, Jr., joins his father in business and quarterbacks the expansion strategies for both companies.

Manor Care acquires Quality Inns (renamed Choice Hotels International in 1990), thereby combining both of the Bainums’ major operations into one public company.
Stewart, Jr., succeeds Stewart, Sr., as Chairman and CEO of Manor Care.
Choice Hotels is spun off from Manor Care and begins trading on the New York Stock Exchange.

Manor Care merges with Health Care and Retirement Corporation. In the 26 years since Stewart, Jr., joined the business, the company’s market value increased from $12 million to $2.4 billion.
The second and third generations of the Bainum Family meet and commit to continuing to pursue collaborative family investing and philanthropy. A Family Council is formed to lead efforts in generational education, entity succession, and communication.

Barbara Bainum succeeds Stewart Bainum, Sr., as CEO of the Bainum Family Foundation.
Third generation leaders work alongside the second generation, assuming leadership roles as their expertise increases. Together, the family starts SunBridge Holdings to invest in new opportunities and Artis Senior Living to take advantage of industry experience.
Subsequent new pursuits include investing in technology ventures, developing and operating hospitality assets through Park Silver, and investing in environmental and agricultural sustainability projects through Tertium.

The family brings together several family office entities and related companies to form White Oak Enterprises.
Brian Bainum is elected Chair of the Artis Advisory Council and White Oak Enterprises. Scott Renschler is elected Chair of the Bainum Family Foundation. Scott and Brian are both members of the family’s third generation.
