Excelsior Orthopaedics is expanding its presence in Niagara Falls with a larger office and longer hours.

The Amherst-based practice is moving within the Summit Medical Campus to a new office in Suite 700 at 6934 Williams Road. The new site is larger and can accommodate more patients.

The practice also increased its hours in Niagara Falls, as two of its surgeons, Dr. Timothy V. McGrath and Dr. Nicholas J. Violante, will now maintain regular hours at the new site each week. McGrath, a Niagara Falls native, specializes in hand and upper extremity surgery, while Violante, a Lewiston native, focuses on hip and knee conditions and total joint replacement.
