I recently had complete hip replacement done on both of my hip's by Dr. Armstrong. The first one in May of this year and the second one done in August, just 2 weeks ago. Both my hips are doing great, they feel better than they've felt in a long,long time. I would definitly recommend Dr. Armstrong. He was very professional to both my husband and myself, He explained things in a way we could understand, always polite, quick to answer our questions. All his staff have been wonderful.
