  • I am forever grateful to Dr. Callaghan for setting my broken wrist after a sudden fall in late March, 2017. The physician on call for Dr. Mc Inerney at Chilton that Sunday, Dr. Callaghan was my God-send. Competent, confident, calm, and kind, he reassured me that my wrist would heal perfectly--and it did! He was not at all surprised by the unusual appearance of my broken bone but simply asked a few questions and began his skilled work and remedied my brokenness. God bless him always!

  • I suffered with chronic crushing pain for over 20 years because no surgeon would remove some hardware in my leg from an old war injury. I eventually developed complications. Dr. Callaghan met with me and after talking to him for 5 minutes, I knew he was the guy. What other doctors were afraid to do was a very simple surgery for him and I'm virtually pain free now. He gave me my life back. He also happens to be a very humble, professional and generally nice guy.

  • Dr. Callaghan was my surgeon after a traumatic accident that injured both my legs. I received high quality care from the skilled hands of Dr. Callaghan. He evaluated my condition carefully and took the necessary steps to eliminate the possibility of infection and did an excellent job with my surgery. Dedicated, honest, friendly, professional and knowledgeable on the latest techniques. Thank you for a successful experience.
