Dr. Danielson operated on my heart in 1986 and 1987. I was a young teenager at the time and remember him visiting with my parents and myself both before and after the surgeries. I remember him as a kind, compassionate, deliberate and obviously very skilled. I will forever be grateful that for the quality of life I have, if not my life itself ,that Dr. Danielson was able to deliver to me on the operating table. I thank God for his skill and my sincere condolences to all of those who love him.

I was born in 1981 with Ebsteins Anomaly and was given two weeks to live. But my parents researched to find the best Dr there was to keep me alive. And they found Dr. Danielson. So on October 9th 1991 I had open heart surgery and it was a very successful surgery. I went on to live a normal life and brought four children into this world, who were all healthy. I would have loved to personally thank Dr. Danielson for given me a second chance at life. I thank God for him and he was truly amazing . Thank you so much. And sorry to the family for your lose.

Shelton Weerasekera on Apr 4, 2018

My son aged 40 arrived in 2000 with advanced Ebsteins Anomaly, and Dr.Danielson undertook a high risk surgery and successfully replaced his tricuspid valve with a porcine valve. He was out of Hospital in about 8 days. It was a miraculous intervention by a brilliant, compassionate surgeon. My son is leading an active life to date.
May his soul rest in peace.

My deepest sympathy to your family. Dr. Danielson performed open heart surgery on me in 1988. He gave me as normal of life as I could have imagined. I will never forget him.

Kay Duzynski on Oct 8, 2017

Doctor Danielson performed open heart surgery on my daughter, Sarah Duzynski, on November 7, 1988. He reconstructed her tricuspid valve. She kept her own valve for 26 years until she needed a replacement. Rest in Peace Doctor Danielson.

I had the privilege of working with Dr. Danielson many years ago -1970, and 1977. He was certainly one of the pillars of my education. He cared about his patients and his residents and played an important role in my life as well as in the lives of countless others.

Cally Hughes on Oct 6, 2017

Sorry for your loss. I was a young nurse at St Mary's in the 3D unit in the 80's. I had a young post open heart kid that had been doing poorly all night despite the fellows best intentions. Dr Danielson came in and said do this this and this.... with some tweaking of Med drips and vent settings the young patient turned around within the hour. He was a gifted practitioner and kind man to work with. He left a legacy beyond all the families and patients he helped. May your family be comforted by memories.

Ishik C. Tuna, M.D. on Oct 5, 2017
