Parking Lot Construction at Concord Office!

We are growing – parking spaces that is! Beginning in early June, Concord Orthopaedics will begin a parking lot expansion project at our 264 Pleasant Street, Concord location. Your safety is our top concern. Please pay special attention when entering our parking lot to follow new directional signs and markings indicating a new traffic pattern. We have made every effort to maximize the available parking spaces during construction. The final result, slated for completion in the fall, will be improved access and 80 new parking spaces! Thank you for your patience and understanding as we embark on this important project to improve patient access and convenience.
