  • Dear AJ,

    Thank you.

    I know I will be seeing you for ongoing review but now seemed an appropriate time to say thank you.

    I really appreciate the calm, compassionate care you’ve given me. From my first appointment I felt very confident that you were the right surgeon for me - and I was correct.

    Thank you again.


  • Dear Dr Collins,

  • Dr Collins,

    Before saying that you are an extraordinary doctor, I want to tell you that you are an extraordinary human being. You are a real lifesaver. I may have talked to God in my prayers and I have experienced favours, empathy and kindness from your services.

    You are an extraordinary doctor and humble surgeon. You have made a great impact in my life including my family at a time when we desperately needed it. You have restored our faith in humanity. Your quiet confidence and compassion has changed our lives and will be spoken about for years to come.

    With thanks,

    G and family

  • Dear AJ,

    A somewhat overdue note to say thank you, officially for absolutely everything.

    There are simply no words to describe properly how much you have done to make my journey easier in all ways this year.

    I will be eternally grateful, not just for the exceptional standard of professional care, but for all that went with it.

    Your helpfulness, reassurance, compassion, understanding and caring are all unparalleled. I am just so blessed to have found you - and with the path you sent me down for my treatment.

    Best wishes,


  • To Professor Collins & Staff, Thank you for your excellent care.

    Thanks also to Deborah who efficiency and kind attitude made it a pleasure to wait in the waiting room.

    Fond regards,


  • Dear Dr Collins,

    Thank you for the excellent care of M.

    We had all felt concern how M would manage being in hospital and having an operation.

    Our worry was unfounded due the care and understanding which was shown.

    Thank you for a good outcome for M.

    Best wishes,

    N & G
