Our family has been under care by Dr Nickelsen for over 30 years. He is a brilliant diagnostician while being very caring and professional. We trust him and his diagnoses and treatments completely. He has always maintained a pleasant and professional staff. He does not give antibiotics unless warranted by the presence of bacteria. Dr. Jim is a wonderful doctor.
