    I believe that Dr. Alwin C. Lewis is among the top doctors in Southern California. He is forward-thinking, pays close attention to your overall health and weight. Dr. Lewis has also written a small book detailing the negative aspect of being overweight. and the problems it can cause with your overall lifestyle. Dr. Lewis is saving lives.

    Dr Lewis is always very attentive and always follows up my bloodwork to explain my results

    Because he is not a doctor who actually cares about your concerns. He did not address my actual health concerns, he refused to do my testing I asked for his bloodwork. And he told me verbatim to not eat for 15 days - which I would essentially starve, he said I should only eat “5 bites of a bar, 2x a day with only water or coffee.” He wants all of his female patients to lose weight. I’m not the only patient of his to be a victim of abuse- there are reviews of this doctor all over the place stating the same thing. I hope the medical board sees this and does a serious investigation.

    The Doctor is doing his best to try to make me as healthy as possible. Sometimes he overlooks more day to day things, while focusing on just one or two more specific things. Overall he is friendly and wants to make sure I'm as healthy as possible.

    Most people would have to switch their insurance to choose a random Doctor on recommendation.
