Mark Smith - Brennan & Smith

Mark Smith


Mark graduated in 1982 with a bachelor of Optometry from UNSW. He worked in suburban Sydney before completing the requirements to gain registration in the UK. Working across various practices in England gave him 3 years of valuable and unique professional experience. When he returned to Australia, Mark was keen to establish his own practice and after some searching decided Armidale ticked all the boxes. He moved with his family in 1988 setting the practice up with his good friend whose name is still part of the now familiar Brennan & Smith. Mark continued with Brennan & Smith expanding the practice to Inverell, Tenterfield and Glen Innes in the following years.

Mark is a highly experienced professional who continues to be well respected in the field, and who is still passionate about his work. Recently he reduced his work hours to be able to pursue more of his outside interests which include cooking, nutrition, fitness and farming, and travelling to see his three children who are spread across the world.

Mark St Ledger


Mark St Ledger graduated from the University of New South Wales with a Bachelor of Optometry in 1982. He continued further studies in London in 1983,  after which he practiced for 13 years in the UK.  Mark owned an Optometry practice in Sydney from 1998 to 2005.

After selling this practice, Mark commuted from Sydney to Armidale for 10 years until settling in Armidale on a more permanent basis in 2015,  and more recently becoming a business partner,  bringing a wealth of experience to his practices in Glen Innes, Armidale and Tenterfield.

Mark is the proud father of two children - Joshua & Georgia.  Outside work his passions include Rugby, snow skiing, travelling and the beach. He played Rugby for Randwick, has skied in resorts around the world, travelled extensively around the globe and belongs to the Clovelly surf club.  He has recently undertaken open water ocean swimming with a desire to do more. 

Mark finds it a pleasure and a privilege to work as an Optometrist in the New England District and hopes to continue to provide good quality eye care to those in the New England area for many years to come.

Kate Mitchell - Brennan & Smith Glen Innes

Kate Darley


Kate graduated from UNSW with honours in Optometry and Vision Science. Kate could not wait to move back ‘home’ to the country to start her career in private practise as an independent optometrist. Kate’s particular interests are in disease detection and management, as well as a holistic management when combating children’s vision. Kate’s therapeutic qualification allows her to prescribe and manage a plethora of eye conditions and particularly enjoys co-managing glaucoma, removing metallic foreign bodies as well as diagnosing and treating a host of sore eyes, such as uveitis. Kate travels between all 4 Brennan & Smith stores and enjoys the challenge and change of scenery each practise offers. Kate likes to offer “quality eye care, NOT cheap eye care” and has been able to offer this in private practise. Kate is also fully qualified to offer CASA (Civil Aviation Safety Authority) Eye examination for pilot licenses.

Outside of work, Kate enjoys working on the family farm, where Wagyu beef and border collie pups keep weekends busy.


Trent Irwin - Brennan & Smith Glen Innes

Trent Irwin


Trent joined our team at Brennan & Smith in 2012 after graduating from the University of New South Wales with First-Class Honours. Born and raised in Inverell, Trent was eager to return to his local community and provide comprehensive eye care to the New England area. He is therapeutically endorsed for scheduled medicines and has a keen interest in ocular disease, especially the retina and prides himself on thorough examinations to provide both the best refractive result for his patients as well as the early detection and treatment of all ocular conditions. In his spare time, you will find Trent on the golf course or soccer pitch and after becoming a business partner in 2017, he envisages himself to remain an important member of the team for years to come”.
