    Dr. Lansang is always attentive, knowledgeable and thorough. In person visits are slightly more helpful because my neck can be palpated and that gives me another level of security.

    Dr Lansing was exceptional. Tremendous technical skill set, and the unique ability to make a patient feel at ease. Her ability to use a bit of humor to defuse the new and difficult period immediately post-transplant was wonderfully handled. World-class Doc.
