Yes, Dr. Wander has been seeing me now for probably three or four years. And whenever I do see him, he is always very respectful. He's kind. He's always up to date on the latest information about my medication that I'm taking and always tells me about different studies that I could possibly be in and gives me his honest and straight opinion about things.

Dr Wander was very patient, empathetic and hopeful with my mother who is [redacted] and hard of hearing. The virtual visit worked better than in person because she lip reads and everyone wears a mask in the hospital. This should be considered with elderly hard of hearing patients. Dr Wander gave her clear options and really raised her spirits which have been very low. We consider ourselves fortunately to have him as our physician.( written by daughter)

I have worked with Dr. Wander since 2021 and he is dedicated to enabling me to live as fully a life as possible with metastatic breast cancer. On his recommendation, I was involved in 2 clinical trials at MA General and I appreciated the team's surveillance. He makes himself reachable and with certainty, he answers my Portal questions or phone calls in a timely manner. He knows me, my medical history and my health intentions for the future. He is organized in my appointments; he gathers information (side effects, new medicines, listens to my living experiences between appointments), he sets up any tests, scans or referrals and when asked, will share the new treatment strategies and medicines from his research or other clinical trials. He actively engages my husband and HCP, answering questions from both of us. One of Dr. Wander's strengths is that he treats me and my disease as individual and unique, with no assumptions and communicates with other providers to ensure I have consistent care and follow-up. I really appreciate his "smarts" and dedication to confronting my cancer disease's twists and turns.
