    As a senior and sometime forgetful, it's good to know that I can take my time and ask the doctor any questions that I might have. This last visit the doctor asked about removing a heart monitor that was put in quite a while ago, out. I'm happy to say it's now gone! Best of all Mass General. Brig is very close to me. I no longer have to go to Boston and I have the best doctors right where I am. Thankyou ALL??

    I transferred to this provider from N E Baptist for the pain blocking shots to my back. I have never regretted this move. At this office a real person answers the phone, and is always helpful, knowledgeable and courteous. With Baptist, no one answers the phone, its difficult to get a call back and they kept getting requests for approvals denied by CMS. This provider always gets approvals and provides quick care. They are great.
