I've always been VERY happy with Dr. Kupferwasser himself. Rarely have I been pleased with the office staff, at the front desk, though the Van Nuys office is more friendly than Tarzana, for sure. But I love the doc, so I'll keep going back and just be prepared for no smiles in reception... I'm not there to see them, anyway. :o)

A phone call got me right into see the doctor. Then it was only a short wait. Kudos! He seems very competent in a German-sort-of-way. Precise. Perceptive. Salient. Unfortunately that precision does not translate well to people. No one said hello when I walked through the front door. Everyone seemed disaffected or out of sorts. Maybe unappreciated. I dunno. But a modicum of efficiency with things but effectiveness with people would greatly help his practice.

I've always found Dr. Kupferwasser to be very professional, interested, a good listener and always willing to discuss and explain details of treatment, medications, etc. in understandable language!
