What others are saying about Chiropractic Works & Dr. Kosta Tsakalos

In 2018 I suffered from a concussion that brought on terrible migraines and neck pain. I went to see my regular doctor hoping for some relief but all I got was a prescription for some seriously strong pills that I really didn’t want to take. I tried everything from physical therapy to seeing two different chiropractors but nothing seemed to work until I stumbled upon Dr. Kosta. After just two months of treatment with him all those post concussion symptoms vanished!! Now I’m a regular for maintenance visits and I can’t recommend Dr. Kosta enough, especially if you are struggling with concussion related issues like I once was. He’s been a game changer for me!
