Having switched Cardiologists 2 years ago, I found Dr. Undesser and his staff, to be friendly and down to earth ( A BIG change from my former, retired Cardiologist). Being in the Healthcare profession myself, I wanted to find a Doctor that treated his patients, the way I'd treat mine..with sincerity, care & respect! Dr. Undesser IS this kind of Man, and it shows. He listens to his patients, and his Nurse, Missy, is also very nice and makes you feel at ease. I am so glad I made the switch!

I went to Dr Undesser to get a second opinion, and while he agreed with everything, he also explained a lot of "why" and "why not" questions I had. The time spent with me assured me his office did not run a "see how many patients we can get through here" practice. I would highly recommend him.

Needed a new pacemaker doctor and found him. Only one visit to him this week but he made me feel relaxed and spent a lot of time with me and would answer any questions that I had. Seemed to know his stuff and I didn't have to wait and hour and a half for him like my last doctor. Would recommend him.

Gee, Iwonder where all thses 5 star ratings came from. I saw this doctor about 3 years ago and he was poor in his reccomendation of what he wanted to do. I had just come fom the Mayo Clinic regarding my heart, he didn't bother looking at the paperwork or even who I saw, what he wanted to do was WAY off base from what Mayo said. I Gave him 2 stars so maybe he can do something for others with what he specializes in. But I can Strongly NOT Reccomend Him.

Dr. Undesser was wonderful. He took the time to explain my condition and what he was going to do to correct it. He answered all questions and explained in more detail if I did not understand or had follow up questions. The day of surgery he again asked if I had any questions or concerns. Dr. Undesser was recommened to me from my heart Dr. in Alaska. The trip to Caldwell, Idaho was worth it. His staff at his office and the staff at the hospital were excellent as well.

I was so very pleased to have a physician that communicated wth me, not at me. He never made me feel that the appt mt. was rushed. He explained my situation well, discussed treatment options, and referred me to a consulting physician, so that I was well informed. He has a calm, kind manner and made me feel that I was a patient and an individual. Glad I chose Dr. Undesser for my appointment.

I have been a patient of Dr. Undesser since I turned 65 (now I am 78) . I had been suffering from a rapid heart rate condition (tachycardia) over 20 years. The condition would come and go with various levels of severity. At one time I even had to be taken to the emergency room where my heart had to be physically stopped and restarted after failed attempts to control it. Dr. Undesser fixed my tachycardia. Since then he has successfully guided me through solving other issues. Very knowledgeable.

Dr. Undesser is very knowledgeable in his field. Yet, when he explains a diagnosis or a procedure, he can put it in terms a layman can understand. He is so personable that the patient immediately feels comfortable with him. I'm a very pleased with his treatment of my condition.
