4 Patient Reviews for
Dr. Geirsson

"After interviewing 4 different surgeons, I had the most comfort with Dr. Geirsson’s approach to repair my mitral valve. The team was very thorough pre- and post- surgery to ensure success.

I was out of the hospital 2 days after my robotically-assisted surgery, and recovering much faster than expected. The team has stayed with me for the last 2 months for follow up calls and visits.

I cannot recommend Dr. Geirsson and his team highly enough for heart surgery, and in particular for the robotic assisted procedures."

"Excellent experience. Dr. Geirsson had a great bedside manner. I felt very comfortable at our first meeting. He answered all my questions.

With regard to my procedure, I had non-invasive Robotic Surgery on Tuesday December 20th and was able to go home 2 days later. After my first night home, I was able to transition to Extra Strength Tylenol, only, for pain management.

It's unbelievable that you can have open heart surgery and be home 2 days later. I feel great and expect to be back to work in less than 2 weeks from my surgery date.

Dr. Geirsson is the man! I highly recommend him."
