I've been part of the UCLA system for only 4 or 5 years, and have had Medicare plus United Healthcare (and now Medicare plus Scan) but in that time, I've had two hip replacements, cataract surgery, and several regular physician visits. I interviewed my Primary Care Physician before signing on, and found her to be knowledgeable, friendly, personable and delightful. Each and every specialist has been pleasant, willing to explain complex ideas, and forthcoming about exams. I'd do almost anything to remain part of the UCLA system. It's fabulous!
