The 49-year-old mother of five represented the seat for one term in 2004 when she beat Xavier Jayakumar Arulanandam from Parti Keadilan Rakyat by a 19,732-vote majority.
The dental specialist who ran her clinic for 10 years, was also an associate professor at Mahsa University from 2009 to last year and had also been active in politics for the last 22 years.
Currently chairman of University Malaya Medical Centre in 2008, Dr Rozaidah, who was appointed as the Women, Family and Community Development Ministry special task officer, said she was confident the people of Ampang would vote for Barisan Nasional (BN) in the election.
"There is much to be done and should be done in Ampang," she told the New Straits Times.
Focusing on the urban poor, BN must look at the affordable housing scheme for the people in the constituency, she said.
"Affordable housing is what's missing in Ampang.
"PKR abolished all this and replaced it with high-cost homes. This is not affordable for many people in Ampang."
The PKR and Pas leaders who held the parliamentary and state seats were heavyweights, she said, but had not done much to benefit the people.
"We did not see much of their faces, and there is not much development in Ampang."
She is confident the electorate will want a new face who is vibrant and energetic in representing them in Parliament.
"We will do our best to serve the people."
