I would like to thank Dr. Danielson for the treatment and care that he gave my father for his recent surgery. My elderly father was very comfortable with Dr. Danielson from the very beginning and mentioned how he appreciated the manner that things were explained in a way that he understood what was going on. Dr. Danielson also did an excellent job in communicating with me and several times post surgery. I live out of state so being able to talk with him personally three different times was very much appreciated. Excellent treatment and care! Thank you!
