William Thomas


In 1976, Bill and his twin brother Bob co-founded Gemini Properties — a real estate operating and investment company. The company’s focus evolved toward seniors housing in 1989 with the founding of Senior Star. Today, Senior Star offers independent living, assisted living, and memory support across 12 retirement communities with over 2,200 residences. A growing company with strong leadership has enabled the brothers to focus their energies on senior and community issues. None is more important than their goal to change the world by ending Alzheimer’s.

Bill currently serves as Chairman of the Board for the Philbrook Museum of Art and serves on boards of trustees for the University of Tulsa, the American Seniors Housing Association (ASHA), and the Cystic Fibrosis Foundation Sooner Chapter. Bill earlier served as Chairperson for ASHA and the Tulsa Community Foundation — the second largest community foundation in the nation.

Bill and his wife Susan have chaired various fundraising events and capital campaigns for LIFE Senior Services, Domestic Violence Intervention Service, Project Woman, and Street School. They also chaired the Philbrook Wine Experience twice, leading it into one of the top three fundraisers of its kind, nationwide. Longtime Tulsa Area United Way (TAUW) supporters, Bill and Bob chaired the 2002 TAUW capital campaign, raising a record-breaking $25 million in the midst of the country’s financial crisis. The following year, the pair served as board co-chairs of TAUW.

Among Bill’s most significant contributions to Tulsa is his seven-year term of board service to the Housing Authority of the City of Tulsa, which included his chairpersonship of HOPE VI, a Public Housing Revitalization Program. This $60 million public-private undertaking eliminated 1940s vintage housing and made way for “Country Club Gardens” — 396 units of exceptional residential apartments for low income and market rate housing.

Bill and Bob have had the unprecedented honor of receiving three distinct awards from the Association of Fundraising Professionals Eastern Oklahoma Chapter — being named as the 2000 Outstanding Volunteer Fundraiser, the 2007 Outstanding Philanthropist, and most recently the 2016 Pillar Award Recipient for philanthropy leadership benefitting the Tulsa community. The Retired Senior Volunteer Program of Tulsa granted Bill and Bob their 2001 Leadership Award and the University of Tulsa named the brothers their 2011 Outstanding Entrepreneurs, inducting them into the Collins College of Business Hall of Fame.

Bill became a Certified Public Accountant in 1977 (Missouri), following the receipt of his Bachelor’s degree in political science from the University of Tulsa in 1974. He resides in Tulsa with his wife Susan.
