Patient Reviews

  • "If going to a hematologist oncologist can ever be pleasant, I can surely testify that my experience here was reassuring and comforting. My concerns were addressed and my treatment was respectful. Dr. Grand was extremely compassionate and explained my tests and my lab results with care. I felt at ease with his tone and his sincerity even when I kept interrupting him while he explained. I was nervous but felt at ease in his presence. Thankful for the professionalism of him and the entire staff."
