George Sledge was wonderful--this was a second opinion for me. I am undergoing chemo at UCSF for a recurrence of breast cancer and was treated at UCSF previously. Honestly, I have been extremely frustrated in my efforts to get my questions answered from both my MO and SO at UC. I brought all my questions to Dr. Sledge and he answered them thoroughly and thoughtfully. I felt a huge weight lifted after my appointment. UCSF is more convenient to my home, otherwise, I would much prefer to receive care from Dr. Sledge.
