My Team

The Team

Successful surgery depends on the good work of a team of people both inside and outside the operating theatre. Without them no surgeon can get a great result. Some, like those in the sterilising department, you will never meet but be assured all are committed to your care.

The Team

Office Staff

Debby Chambers

Debby has been personal assistant to Dr Caldwell for over 20yrs, first at Toronto and now here at Lingard Private.

  • Making appointments

While Debby is there to answer most of your queries, some medical questions are best directed to Dr Caldwell, who is only too happy to discuss your concerns with you.

Dianna Dunn

Dianna Dunn - Receptionist

Di has been assisting Dr Caldwell as typist and receptionist in the office for over 10yrs. She is similarly capable in helping with your questions and care.


Dr Caldwell and his anaesthetists have worked together for over 15 years. They have been carefully selected and are all experts at looking after patients having knee and hip surgery.

On some occasions, such as after hours or during holiday periods, other anaesthetists may help out.

Anaesthetists are not employed by their surgeon. Your anaesthetist will send a separate bill based on:

  • The surgical procedure
  • Your general health (ASA Score)
  • The complexity and
  • Length of the anaesthetic

Recent Additions

Dr Andrew Hart and Dr Jonathon Rothwell are recent additions to the team covering Thursday lists at Lingard. They are both experienced and reliable anaesthetists.

Assistant Surgeons

Almost all operations require an assistant surgeon to help with the procedure. Over the years they become expert at the various procedures and are invaluable in the efficient and smooth progress of each case.

The assistant is not employed by Dr Caldwell and will send a separate Assistant Account. This fee is based on the length and complexity of the surgery and the Medical Benefits Schedule. It is usually 20% of the surgeon’s fee.
