Straight shooter who is patient centered has an excellent bedside manner.
An excellent Doctor Who really knows his stuff. I'm amazed at how quick I am up and moving around after my full hip replacement. 10 out of 10 would recommend.
He was pleasant, lisrened to my concerns and answered my questions and clearly explained information. And his medical assistant Nancy was also very pleasant and patient with me. I felt that they were a good team.
Dr gave me a shot of cortisone that is helping with my knee pain.
I had my hip replaced on March 20. The process from consultation through the last appt was seamless. Dr. Allen was informative and understood what my goals were - to return to to trail running. I plan to seek Dr. Allen help for any of future hip and knee issues. Thank you also to each person I came into contact with at CORE.
