According to her brother, Robert Rendon, "Rosemarie possessed a love for her neighborhood. She grew up in the Guadalupe neighborhood and was very instrumental to deal and address neighborhood concerns. She was concerned with issues involving small children and persons with disabilities. In 1979, she was diagnosed with Multiple Sclerosis, but she remained active through all stages of her battle with MS. Rosemarie did everything from organizing marches to rid prostitution in her neighborhoods, to laying down on Main Street to fight for FLEXTRANS."

Ms. Rendon is known for being instrumental in partnerships and coalitions, being a team builder, bringing affordable new housing projects for senior citizens to the west side of the City, involving the Spanish speaking community, naming Guadalupe Park located at 619 West 500 North, resurrecting a statue of Our Lady of Guadalupe in the park, and getting Utah Transit Authority to make their buses handicap accessible.

She was a spokesperson for persons of low income and minorities. She was successful in getting the State support stipend increased for nursing homes that gave the elderly a higher monthly allowance. Many low income areas were funded with Community Development Block Grant funds due to her efforts.

Neighborhood Housing Services recently named Rendon Court in recognition of Rosemarie’s dedication to her neighborhood. This 12-unit, single-family mixed income dwelling development will be located at 650 West 250 North. Construction is estimated to begin in March and is expected to be completed by the end of 1999.

Former Mayor Palmer DePaulis worked with Ms. Rendon throughout his term as Mayor and states, "It didn’t matter what the issue was, Rosemarie was right there to make her neighborhoods safer and help children. I knew her when she was confined to a wheelchair, but this did not stop her from participating. If things were not getting done for children, she was right there like a mother hen watching out for their well-being. She was never afraid to articulate her displeasure. She wanted to get things done. She gave her energy and time. Everything was for the people of her neighborhood. She possessed a dynamo of enthusiasm and energy for people in her area. She particularly looked out for children. She has a heart of gold."
Former Mayor Ted Wilson describes Ms. Rendon as the most energetic and effective community organizer he has ever known. Because of her tremendous leadership skills, she was asked to serve on the Advisory Board of the Hinckley Institute of Politics. During her service on the board, she would take FLEXTRANS. "Rosemarie possessed lots of diplomacy, but was tough as nails! She is a beautiful, lovely soul, and I loved working with her. She was sensitive to everyone’s needs," Mr. Wilson said.

Ms. Rendon’s involvement with her community is overwhelming. She was a founding member of the Disabled Rights Action Committee. She worked on disability issues locally, regionally and nationally. In 1990, she participated in the big march down Pennsylvania Avenue for ADA. She was also involved with the Salt Lake City Police Review Board, Neighborhood Housing Services, Crossroads Urban Center, Utah Issues, Salt Lake City Housing Authority Board, and the former Citizens Congress.

Barbara Toomer, member of the Disabled Rights Action Committee, states, "Rosemarie was a leader with a vision willing to go forth to make sure her visions were accomplished."
