  • Highly recommend! The Best Chiropractor I have ever had!!! Friendly and warm staff, on time, and professional. I couldn’t lift my arm at all and was in excruciating pain in shoulder, neck and shoulder blades. I immediately felt better after adjustment and I woke up the next morning and it was like a miracle…no pain and could lift my arm. I am sleeping better. I will be making this a routine. I am so happy I found Dr Jack! What a difference! Thank you!
