Her deep understanding of the industry, unmatched energy and passion for improving patient lives and commitment to creating value for shareholders, customers and colleagues make her the ideal candidate to lead Parexel through this exciting next phase.

“It����ֱ�� been a privilege to lead Parexel during this critical period in the company����ֱ�� strategic transformation,” said CEO Jamie Macdonald. “Our commitment and focus on the patient have continued to differentiate Parexel, drive our focus on innovation and ultimately strengthen our ability to develop new therapies that enhance and save patient lives. We have an incredibly talented team and leader in Peyton as our next CEO.”

He continued, “On a personal note, I’m proud of my time with Parexel and to have been part of the CRO industry for 30 years. With the company well positioned for growth, now is the right time for me to retire and spend more time with my family. Following the transition, I look forward to continuing to support Parexel as a Board member and remaining an investor. I’m truly grateful for my time with this amazing organization and to have been part of such an incredible team.”

I’m proud of our growth and accomplishments and look forward to working with Jamie on the transition and with the Board and our leadership team to build on this momentum as we execute on our strategic initiatives, continue profitable growth and generate value for our stakeholders.”
