      I was especially pleased that Dr. Callsen reviewed and completed my MOLST form. And encouraged me to keep up with what I can. Also she assisted in making sure I can have a procedure in two weeks for pain management

      Very clear as to blood and urine analysis. Lab test items which are notes are never discussed.

      Dr. Mary Callsen listened to my apprehension on taking a cholesterol lowering statin again after I went through an unpleasant experience with simvastatin a few years back. She told cholesterol, unfortunately, goes up with advanced age and advised to take a different statin, Atorvastatin, which agrees and shows good results with many patients. So I started to take her recommended doses of 10 MG daily and it already showed great results. So far I tolerate the new statin quiet well.

      Provider is excellent. However, it is extremely difficult to get an appointment with her without waiting months.
