Diana is in the top five doctors I've ever seen in my life. She is so caring and is just a great person. As a doctor, She really listens to your concerns and does her best to address them. Her follow-up is also above and beyond. At UCLA I have never had such great follow-up and care in the last 5 years. She stands out as exceptional.

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!
