The front desk associates and nurses were very friendly and attentive. My Dr reviewed all my records in detail with me and was very thorough when going over my care options. Dr Penn was wonderful. Looking forward to seeing her again. Thank you UCLA Health Santa Barbara team!

Dr Penn is smart and respectful, she was fully informed about my health and care since we last met, she had gone to great lengths to get compete information about my unusual circumstance to assess pros and cons of radiation, and she clearly and thoughtfully answered all my questions.
