    Dr Gus was excellent. I wish I had met him when I was first diagnosed with breast cancer. He is knowledgeable, detailed and compassionate. I learned more about my cancer in this appointment than any other prior visit. He went over my full episode of care from the date of diagnosis to my surgery and final pathology. I was resistant to conservative therapy but he helped me make an educated and informed decision regarding radiation therapy. I will be in good hands for this next stage of my care. His entire team was supportive and caring. Well done Multicare in having this provider on your patient care team.
