Self-Help for the Elderly has offered San Francisco seniors extra support through an escort program.
But that program is being scaled back.
"This year, our senior escort program was cut back by $100,000. I'm glad we still have the program. But that means many seniors don't have chance to meet up with their doctors during the time they need to go because we have a long waiting list now," said Anni Chung, CEO of Self-Help for the Elderly.
Self-Help for the Elderly has also distributed ring cameras to seniors.
Advocates say that offers seniors extra assurance if they live alone.
"We installed almost 2,500 rings between 2021 and now throughout the Sunset and Richmond for the seniors," said Manson Leung with Self-Help for the Elderly.

"This year is last year of the program. We hoping to find funding to extend the program beyond 2025," said Leung.
Community advocates like Manson Leung say more help for seniors is needed.
"With Asian seniors, because of the language barrier and the cultural background, they are more vulnerable than the others," said Leung.
Grandpa Vicha's family says they hope what happened to their loved one will lead to improvements that help others.
"We don't want anyone to go through this pain," said Monthanus Ratanapakdee.
Supervisor Alan Wong says the fifth anniversary of Grandpa Vicha's death is an opportunity to stand against anti-Asian hate and to commit to preventing violence against all seniors.
