Early years

Vollmer was born in Syracuse, New York, and raised in the Dallas-Fort Worth Metroplex region in Granbury, Texas. As an age group swimmer, Vollmer swam for coach Ron Forrest at the Fort Worth Area Swim Team (FAST).

In 2003, Vollmer underwent heart surgery to correct a condition called supraventricular tachycardia, which produces a quickened pulse rate of about 240 beats per minute. After that surgery, an electrocardiogram indicated to her cardiologists that she might have the Long QT. Then, further testing ruled out this condition. Her physicians recommended that she always have a defibrillator at the poolside whenever she swims in case of a heart emergency.

College career

Vollmer first enrolled in the University of Florida, and swam for coach Gregg Troy's Florida Gators swimming and diving team in National Collegiate Athletic Association (NCAA) and Southeastern Conference (SEC) competition in 2006. As a freshman, she earned four honorable mention All-American honors. After her first year, she transferred to the University of California, Berkeley, where she finished her NCAA and Pacific-10 Conference career competing for coach Teri McKeever's California Golden Bears swimming and diving team from 2007 to 2009. Vollmer was the Bears' most valuable swimmer for three consecutive years, the Pac-10 Swimmer of the Year in 2009, and the 2008-09 recipient of the Honda Sports Award for Swimming and Diving, recognizing her as the outstanding college female swimmer of the year. She earned 20 All-American honors as a Golden Bear swimmer, won an individual NCAA championship in the 100-yard butterfly in 2007, and led the Bears to their first NCAA team championship in 2009.
