Rose spoke of the incident to her closest friends and didn't pursue the matter because she feared her nonprofit might somehow suffer, she told CNN.
But when Rose heard of similar accusations against Filner in recent weeks, she called the victims hotline.
• Sharon Bernie-Cloward
Sharon Bernie-Cloward, president of the San Diego Port Tenants Association, relayed her allegations against Filner to KPBS, along with three other accusers. She said when Filner was running for mayor in 2012, he approached her at a political event.
"He touched me, actually groped me on my backside inappropriately," Bernie-Cloward told KPBS. "I was left there startled and fearful. In fact, I actually had someone walk me to my car that night."
• Patti Roscoe
Patti Roscoe, a prominent businesswoman in San Diego's tourism and hospitality industry, told KPBS that on numerous occasions, Filner "put in me what I guess now is the famous headlock."
"I felt fearful, even as well as I knew him, because it was an invasion into my space," Roscoe told the network. "And he would come in and try to kiss me on the lips and I'd have to squirm to get away. And just as recently as a few months ago this happened. I turned and he just slobbered down my chin.
"And I was so violated and so offended. It's just such a terrible invasion."
• Veronica "Ronne" Froman
Veronica "Ronne" Froman, a retired Navy rear admiral and San Diego's former chief operating officer, described to KPBS an encounter that she said had with then-Congressman Filner a few years ago at a meeting at his office after everyone had left.
"He stopped me and he got very close to me. And he ran his finger up my cheek like this and he whispered to me, 'Do you have a man in your life?' " Froman said. "I jumped back. I was very, very startled. And I said, 'Yes, I have a man in my life.'
"And he said, 'who?' And I said, 'Linden Blue.' He says, 'Oh, of the Blues Brothers?' And he says, 'Maybe we can get together sometime and have lunch and he can support me for mayor.'
"I was really rattled. I got in the car with the two guys I was working with and I told them never to leave me alone in a room with Bob Filner again."
• Joyce Gattas
Joyce Gattas, a dean at San Diego State University, told KPBS that she had several "interactions" with Filner "where he's held me too tight, a kiss on the cheek which is inappropriate, hands on the knee that last too long."
Gattas, who helped craft the university's sexual harassment policy, said she has often seen Filner make "sexual comments to others. And I've seen the interactions with others when they cringe. I've experienced his sexual innuendos with me at various events that, again, have left me in that strange feeling of: This is inappropriate, this is unwanted and this shouldn't be happening."
Filner's chief of staff Vince Hall resigned this month via Twitter, citing his position "as a lifelong activist for women's rights and equality."
The mayor's fiancee, Bronwyn Ingram called off their engagement, citing his behavior in a statement issued last week, and she has now joined calls for his resignation.
