Diana was absolutely amazing! From the beginning of my appointment she made me feel like she truly cared. She took the time to explain my options and made me feel like I wasn?t going crazy. Severe back pain had finally taken its toll and I had not been able to reach my regular doctor. I was afraid to go to an urgent care and have my concerns brushed off. Diana showed concern from the very beginning and ordered x-rays. I received the results within hours. I will be following up with UCLA orthopedics and I am so grateful to have met Diana and I can?t say enough about her care. I wish there were more like her. Thank you Diana!

Diana is truly one of the most extraordinary nurse practitioners I?ve ever had the privilege of meeting. From the moment you walk into the room, or in today?s case and Virtual visit , her warmth and compassion immediately put you at ease. She listens deeply, with genuine empathy, and makes you feel completely seen and understood. She not only provides exceptional clinical care, but she also carries wisdom, patience, and a gift for explaining things in a way that is both clear and reassuring. What sets Diana apart is her combination of medical expertise and her remarkable ability to connect on a human level. She treats her patients with the utmost kindness, respect, and care, and it?s obvious she is passionate about what she does. She truly embodies what it means to be a healer. UCLA is lucky to have her, and I feel so grateful for the opportunity to have been under her care. Diana is everything you would hope for in a provider, knowledgeable, empathetic, attentive, and genuinely invested in her patients? well-being.

Amazing ?Nurse Practitioner?, Diana Cizbadija, provided me with a ?Primary Care? Pre Op Exam for my upcoming hip replacement. I remembered her excellent medical work from a few years ago at UCLA Immediate Care, Thousand Oaks, when she stitched up my right leg that had accidentally been badly gashed, requiring ten?s and ten?s of stitches. She did a beautiful job then, as she did today with the Pre Op!
