This site is designed for use by existing patients, new patients and by all those seeking to achieve optimum health.

    Mary K
  • "To be honest, I was very hesitant and a little skeptical of seeing a chiropractor, but was encouraged by co-workers to give Chiropractic First a try. I am totally hooked now. I went from being overrun with pain to not much pain at all and came off of medication. Everyone there is absolutely magnificent. They love all their patients and it shows tremendously."
    Renee C
  • "Love the whole body approach used! Easy to get same day appointments. Care is great for acute pain and general wellness."
    Kerri R
  • "Dr Andrew is the best. Knowledgeable and has helped me so much. Had so much pain in my lower back I couldn’t handle anyone touching it and now I’m able to handle my husband & kids touching my back with tears coming to my eyes. Thank you so much."
