I do not recommend Dr. Giesen. In the consultation with him to for heart disease indications, as my brother and father had heart attacks, he did not offer any insights or testing. I asked him if would prepare a letter to my doctor who advised me to consult with a cardiologist, he said the paper he gave me would be the information he would provide to my doctor. The paper showed my vital signs plus, height, weight, and BMI. That's it. Of course, my doctor who had asked me to see a cardiologist, said the information was useless.

The doctor took a lot of his time & effort to help my daughter and myself in understanding where I was in this process of repairing or mitigating my issues with heart problems. He laid out a logical plan of attack, with a number of possible other options in case this plan didn't give the results we expect. He showed us the difference between A-fib - A-flutter, with personal hand drawn illustrations.
This healer took time to answer our questions clearly & with great kindness & Patience. I feel very good about my chances for Improvement with our plan. I would hope everyone were fortunate enough to have a cardiologist with his knowledge, and personal touch. It was truly my pleasure to get information & care from him & his excellent staff.
