Chief Executive Officer: Carina Ortel

Chief Executive Officer: Carina Ortel

In 2006, I left a promising advertising career in my homeland of Germany and traveled to Peru, where I served as a translator for volunteer doctors, worked in a kindergarten, and launched a fundraiser to help disabled children and adults.

It felt good to make a difference.

When I returned home, I received my annual donor update letter from DKMS in Germany. I opened the letter and decided to apply for a job. So began my rewarding journey in the fight against blood cancer.

From the start, I fell in love with our organization and mission. For nearly 8 years, I served in various capacities including marketing, operations, and corporate budgeting and reporting. As Corporate Secretary, I worked closely with our global board and founder on strategic planning, and gained an in-depth understanding of the lifesaving work we do.

What inspires me most about DKMS is that we help ordinary people get the opportunity to do something extraordinary – give another human being a second chance at life. Every day I am amazed by our people – our passion to help, the way we collaborate, and the way we never give up. I am humbled by the selfless generosity of our donors, and the strength, grace and spirit of our patients.

It is my life’s greatest honor to lead this brilliant organization as we expand our reach, increase our registrations and help save more lives.

We are making a difference and we will continue working together every day to achieve the dream of connecting every patient in need of a bone marrow transplant with a donor who can make it happen.
