“Mr. Dirk Strauss is, in my opinion, one of, if not the finest surgeon in the world for retroperitoneal sarcomas. When I was diagnosed with a retroperitoneal mass, I searched extensively for the absolute best specialist possible because I knew my situation required someone truly exceptional. As a dual American-British citizen whose father was also a surgeon, I had the opportunity to research and seek opinions internationally, including from contacts at MD Anderson in Houston, one of the world’s leading cancer centers. After everything I learned and after finding Mr. Strauss, there was no question in my mind that he was the right surgeon for me. I was incredibly fortunate to be treated under his care at the Royal Marsden. From the very first appointment, he inspired confidence. He always approaches patients with a calm, positive demeanor, a smile, and genuine compassion. He has a rare ability to make you feel safe and reassured, even during the most frightening moments of your life. He is not only an extraordinary surgeon, but also an incredibly kind and caring human being. The surgery he performed on me was technically extremely difficult, and I truly believe only a handful of surgeons in the world could have achieved the outcome that he did. The mass was ultimately found to be leiomyosarcoma, and thanks to his expertise and care, my outcome has been excellent. I will never be able to express how grateful I am for his skill, dedication, and compassion throughout the entire process. If anyone has a condition within his specialty, there is nowhere else in the world I would rather be than in Mr. Strauss’s hands at the Royal Marsden. I could not recommend him more highly.”

I always felt in safe hands.”
