effanie in particular was one of the bravest people I've ever met," said Sen. Andrew Rice, D-Oklahoma City, the author of Steffanie's Law.
Memorial contributions can be made to the Truth Church in care of the McClain Bank in Noble or to the Oklahoma Oklahoma Brain Tumor Foundation, 820 NE 63.
Contributions to Truth Church will be used to build a playground, Collings said.
Contributions to the brain tumor foundation will be to help others going through similar situations, he said.
"We agreed it was to help others," he said.
In February after speaking to a Senate committee that approved Steffanie's law, Collings said she was in the final stages of her illness.
He said his and his family's efforts on the legislation would be to help others.
Funeral services will be at 1 p.m. Saturday at Truth Church, 48th and Etowah in Noble, under the direction of McMahan Funeral Home.
