    Dr. Gaensler has a unique capacity to make her patient feel part of the solution. She not only works to impart her extensive knowledge of hematological issues as clearly as possible, but has the background and interest to instruct the patient on general health issues. She has looked out for me on numerous occasions over the 16years that I have known her.

    Dr. Gaensler is an excellent heme onco.... She is not a warm and fuzzy type doc. However, I have always got the impression that she is very smart and probably one of the best heme oncologists at UC (hopefully). She does not waste time during the appt.
