- The purpose of my visit was to seek a second opinion on treatment to date. Professor Gerlinger provided a comprehensive review in a most supportive manner, including clarification in a number of areas. A most worthwhile visit.
- Marco has been incredible. After an NHS surgical diagnosis of “there is nothing we can do for you”, Marco reassured me that, with the right oncological treatment, we’d change their minds. The treatment has been effective and he has been empathetic and fun, thoughtful and kind,
- Professor Gerlinger is always very professional. He treats you with respect and empathy at all times. He is always readily available and easily contactable should you have any questions or concerns. He is very thorough at appointments and is always honest and supportive.
- Prof Gerlinger is a superhero! He is not afraid to push boundaries, bringing my difficult cancer under control with complex, intensive treatment which not only got me to surgery but has also given me much of my life back. With Prof Gerlinger's expert care and guidance I have been able to do things I couldn't have dreamt of amidst chemotherapy such as sports, big events and travel. At every consultation he is calm, cheerful, honest and reassuring. A truly wonderful doctor.
- Helpful and understanding support was most appreciated.
- Prof Gerlinger gave a second opinion appointment very quickly after my initial enquiry. He was warm and open in his manner and I felt at ease to ask questions. He gave me a detailed and helpful view of the clinical picture and recommended some new avenues.
- Very thorough, very clear planning. Very friendly, a good listener, an excellent communicator! I would highly recommend Prof. Gerlinger to my friends/family.
- Our experience with professor Gerlinger was positive from start to finish. He was very professional, empathetic and thorough. He gave us hope and confidence in our treatment plan and the future care in very unsettling circumstances.
