The Tulsa Day Center has been up and running for 30 years.
The Center celebrated Thursday with the unveiling of a painting of one of its biggest supporters, Henry Zarrow.
A local artist donated the painting to keep Zarrow's memory alive at the center.
"We don't forget Mr. Henry," said Sandra lewis, Executive Director for the center. "He passed away, I think it's been three years now. I don't want them to forget what he brought to this organization."
The center helps homeless people become self-sufficient.
