in Valparaiso, Indiana |
We have been going to this Dr. for several years and have never been dissappointed. He has always diagnosed us correctly and followed through with restoring our health. He always takes time to talk about your health and your family. Dr. Maddack and his office girls have always been friendly and helpful. When we have an appointment, my husband and I always go together. We both love life and people, therefore while we are there, we have the staff laughing, which makes a better day for all.
