Dr. Hennecken Is a very focused cardiologist who measures risks and will bring In other Drs. when needed. Thank you.

I have been in Dr. Hennecken's care for several years and appreciate the thoroughness he brings to each consultation, even reviewing notes from other specialists to advise from a global perspective. (treatments which can affect hypertension for instance). He comes across as a specialist and a common-sense, hands-on caregiver as well.

Dr. Hennecken is an excellent physician.
