5/5
Wow! Needed an ortho evaluation for a foot injury/pain. Went to the new Ortho MA office in Wilbraham on a Sunday morning. I cannot say enough about how much I was treated with respect, kindness, professionalism, and received diagnosis and care in this state of the art office. The PA helped work out a great treatment and follow up plan. Amazing!
