    I am very sorry to hear of Dr Antonson’s passing. When he was at Children’s, my daughter was a patient of his. He was very helpful in understanding what was going on and why, and for that I will never forget him. Please accept my sympathies and it is of comfort to me that Heaven has gained a caring Angel.

    I was saddened by the news of Dean’s passing. I have only know Dean for a short time, meeting him through the RCIA program at St. Robert’s He was a genuine man of faith, and such a kind heart, He will be missed by many of us at St. Robert’s. Rest In Peace Dean

    I was so sad to hear about Dr. Antonson. I worked as a child life specialist alongside for many years in the 90’s at Children’s and he was truly one of a kind. I was delighted to cross paths with him while also working at Nebraska Medicine for the past 20 years. I have nothing but fond memories of him and his amazing bedside manner. He was always upbeat and armed with a smile. Kids and families adored him as well as any staff member who knew him. What a loss for not only the medical community, but for all of us as he truly made the world a better place. Rest in peace….

    Dean took care of my son for many years at Children’s as we battled through severe bowel issues as a baby. I believe he is the only reason that I got to see my son get married this summer. God Bless you Dr. Dean!!!

    So sorry to hear of Dr. Antonson’s passing. My son was a patient of his starting at 12 weeks of age (my son is now 20). Dr.Antonson was brilliant, compassionate and had a great sense of humor. My kids called him “the fun doctor.” He listened to me as a mom and my son finally got the tummy relief he needed and was finally sleeping at night. Dr. Antonson will be missed but never forgotten.
