Care Philosophy
I was taught to 'treat the patient, not just the disease.' Spending time trying to get to know each patient's unique needs and priorities allows me to better individualize the management of each patient's cardiovascular care. This approach helps me develop patient relationships based on mutual trust and this, in turn, helps me be a better doctor to each patient.

Interests & Activities

Dr. Klassen's reputation is impeccable! Banner Health is blessed to have this outstanding doctor in their health care ranks. At my age - I have been to man doctors and Dr. Klassen is second to none! He takes time - he does not rush a patient - the patient feels very special - and his knowledge base and experience show through with all that he shares to explain/assist the patient in what heart issues/concerns they have! The patient leaves feeling very valued and cared for - a feeling inside that gives a person hope and resolve with heart concerns they may have. Dr. Klassen's integrity, confidence, clarity on all cardiology issues imparts a calm to the patient.
