    How was your appointment with Dr. Onaitis?

    Nov 23, 2020
    Dr Onaitis is my life saver. Literally! And he is a consummate professional. When I first met with Dr Onaitis it became quickly evident that I was in the best hands and he was going to take good care of me. When I was in NY attending a Lung Cancer fundraiser a year later, the founder asked me who my doctor was in CA. When I told him, he said "you are in great hands - he's one of the smartest and the best." I knew that already.
