A concerned, personable, and talented orthopedist
As a hip specialist he is one of the best. Heard it from many people and got to experience it for myself.
One of the best !! Goes over and above to assure the best care.
Dr Mullen was knowledgeable, professional, and attentive during the visit.
The man is awesome
Thorough and caring
Awesome! Put me at ease immediately and was straight forward with all my options. I was able to understand and make my own decision.
I have know, and been going to Dr. Mullen since he first came to Newtown. He has always cared for me with his knowledge, caring and great skill. There is no other orthopedist with whom I would trust to care for me.
Highly skilled, replaced both of my knees! Full motion and flexibility now. An excellent orthopedic surgeon...highly recommended !!
