After her time in the House, Mason Gray received her Juris Doctor degree from the University of Tulsa and was a municipal judge from 1994 to 1999.

She was elected as District Judge for Oklahoma County in 1999 and served in that position until her death in 2011 after battling with breast cancer.

She was the middle child of three and spent a large portion of her childhood summers reading books while recovering from knee surgeries.

When elected, four other women from Tulsa served alongside Gray, including Penny Williams, Helen Arnold, Arlene Baker and Joan Hastings.

Gray did not choose to run for re-election a third time and instead started a family with her husband and went back to school.
