Abby Johnson, 29, used to escort women from their cars to the clinic in the eight years she volunteered and worked for Planned Parenthood in Bryan, Texas. But she says she knew it was time to leave after she watched a fetus "crumple" as it was vacuumed out of a patient's uterus in September.

'When I was working at Planned Parenthood I was extremely pro-choice," Johnson told FoxNews.com. But after seeing the internal workings of the procedure for the first time on an ultrasound monitor, "I would say there was a definite conversion in my heart ... a spiritual conversion."

 Johnson said she became disillusioned with her job after her bosses pressured her for months to increase profits by performing more and more abortions, which cost patients between $505 and $695.

"Every meeting that we had was, 'We don't have enough money, we don't have enough money — we've got to keep these abortions coming,'" Johnson told FoxNews.com. "It's a very lucrative business and that's why they want to increase numbers."

A spokeswoman for Planned Parenthood told FoxNews.com that it offers a range of services at it 850 health centers nationwide, providing pregnancy tests, vaccinations and women's health services, "including wellness exams, breast and cervical cancer screenings, contraception, and STD testing and treatment."

"Planned Parenthood's focus is on prevention," wrote Diane Quest, the group's National Media Director. "Nationwide, more than 90% of the health care Planned Parenthood affiliates provide is preventive in nature," explaining that a "core component the organization's mission is to help women plan healthy pregnancies and prevent unintended pregnancies."

But Johnson said her bosses told her to change her "priorities" and focus on abortions, which she said made money for the office at a time when the recession has left them hurting.

"For them there's not a lot of money in education," she said. "There's as not as much money in family planning as there is abortion."

Without a doctor in residence, she said, her clinic offered abortions only two days a month, but the doctor could perform 30 to 40 procedures on each day he was there. Johnson estimated that each abortion could net the branch about $350, adding up to more than $10,000 a month.

"The majority of the money was going to the facility," she said.
