After having been to doctors at Cooper & Penn I learned of Dr Sundermeyer. He is both knowledgeable & compassionate. His calm manner of speaking is comforting & it amazes me- he’s never kept me waiting but I’ve never felt rushed & I think I’m not the exception.

Dr. Sundermeyer is a great doctor! He took the time to listen to my situation, explained the tests I had previously had done, and really seemed to care. I highly recommend Dr. Sundermeyer.

Dr. Sundermeyer is a remarkable clinician and a compassionate person. Trust is the most important thing in cancer care and his knowledge and expertise is so evident. Beyond his comprehensive clinical care, he is so kind. I have been cared for by so many doctors over the years, and Dr. Sundermeyer is top of the class.

My husband and I met with with Dr Sundermeyer after having a horrible experience with a hematologist with another hospital. Dr Sundermeyer started off by asking us how we're handling everything and took the time to hear our story and get to know us. He is truly a compassionate and knowledgeable doctor that puts his patients first. I would recommend Dr. Sundermeyer to anyone. We're very glad to went for a second opinion.
