What Dr. Tredinnick’s Patients Have to Say…

  • Dear Dr. Tredinnick: My husband and I would like to thank you for the fantastic work you did in putting my ankle back together. Everyone is apprehensive when coming in through the ER – but we were very grateful to have you on call that night. You made us know that all would be well again. Through the surgery, casts and now boot (yeah) we are so pleased. Thank you for being the thoughtful and extremely skilled doctor that you are.  


    — Skip & Sharon H.


  • Dr. Tredinnick:  Thank you so much for the wonderful job you did with Chris’ shoulder. He has no pain and his recovery has been great. This has probably been one of his best years in baseball.

    Thank you
