Daniel J. Guillaume, MD, MS

Our son had a craniotomy performed at 4 weeks old and Dr. Guillaume was completely reassuring and confident in his plan and his team. He was conservative in his approach, meaning he waited as long as he could before performing the surgery, so our son could grow as much as possible, and make his chance of survival the highest possible. The plan worked perfectly and you would never know to this day my son had any procedure done to his head at all! Dr. Guillaumes bedside manner and genius mind are a miracle combination for the people of Minnesota and surrounding areas!

He knows his job.

He is a super hero with the power to go into a child's brain and fix things. Pediatric neurosurgery is one of the most difficult areas that a doctor can go into, and he's really good, putting him amongst the greatest doctors in the world. He's also a really nice person, and caring, and devoted. I really can't say enough good things about him.

I have been meaning to do this for some time and today is that day. Dr. Guillaume is an outstanding neurosurgeon. My son had a brain tumor that was making my son legally blind in both eyes, loss of color vision and daily headaches. We chose Dr. Guillaume because I believed he knew better what to do because he knew what this tumor was and he elected for a less invasive surgery. At Mayo Clinic they wanted to do two brain surgeries! One to biopsy it and the other to remove it or do radiation. And they just kept trying to sell us on the "Mayo Experience." Clearly we made the right choice. My son's eyesight to include color vision returned. While it will never get to normal levels it is good enough that my child will be able to play basketball this year for the first time ever. I cannot recommend Dr. Guillaume highly enough.
