Tracey Derwin

Front Desk Coordinator

Tracey Derwin, Front Desk Coordinator

More than likely, when you phone the Practice it will be Tracey that takes your call. With over 30 years in the dental industry, Tracey has occupied all roles in a Practice and uses this to her advantage at the front desk. Traceys’ clinical knowledge means you can talk to someone on the spot and if she doesn’t have the answer, she will find it pronto!

Tracey is driven by getting the task done and providing the best outcome for her patients. Always ready to assist in which ever she can, it only takes a question to get Tracey up and running.

Speaking of running, Tracey is a passionate soccer player and competed at the Masters Games in 2017. Living nearby and mother of three adult children, Tracey loves spending time with her family and playing lots of sport on the weekends.


Marina Maxhuni

Practice Manager

Marina Maxhuni working with Sara Lonergan

Marina joined Dr Sara Lonergan at Tooth Sparkler in 2015 and brought with her extensive experience acquired from time spent in general dentistry, orthodontics and consulting in Practice Development to dental practices in NSW and QLD.

Along with a Diploma of Professional Practice Leadership and Cert 4 in Trainer & Assessor, Marina is well equipped in managing all areas of Practice. Marina is motivated by creating strong foundations for the practice which allows the team to perform their best so they can provide our patients with exceptional outcomes. “Seeing happy patients with results they thought they could never achieve is what makes me want to come to work each day”.

Living locally, Marina enjoys spending time with her family, the chooks and her fur baby. When not at the Practice, Marina loves dabbling in recipe creations and trying out new things – although she says there are more disasters than wins!
