I believe they are now at 400 Boston Post Road, not 631. I was in extreme pain a few days ago when something in my back or spine just got messed up when performing a routine«roll over in bed» move. Age, you know. After a sleepless night spent unable to stand/sit/squat/bend and move in general, I called Sudbury Family and was given an afternoon appointment. But when I said it was an emergency, they said the doc could see me immediately. The doctor was even willing to see me on his day off if I was in great pain. Doc Bob takes his time explaining details to a layman like me and wasn’t impatient when I ask obvious questions. More importantly, he was able to help the pain! This was the first time I’ve visited a chiropractor. Thought I entered a skeptic, I left convinced and amazed. Having my joints cracked a few times now seem essential. I do think the service is very important. It was important to me that when I needed help, they helped, and fast. There are a few other chiropractors in Sudbury and I haven’t tried them yet, but I’m really happy and grateful I found this place when I did.(happy face)
