Bill Kalis

Dr Bill Kalis - Principal dentist

Dr Kalis attained his Bachelor of Dental Surgery degree from the University of Sydney with First Class Honours in 1994 and following a course of postgraduate study, a Graduate Certificate in Clinical Dentistry from the University of Adelaide in 2007. He is committed to ongoing training and professional development, attending numerous courses and educational programs every year, both locally and abroad. For over a decade, he maintained an active teaching and organising role through his various activities within the Australian Society of Implant Dentistry culminating in appointment to both State and Federal Presidency roles and is currently engaged by Osseo Dental as a speaker and trainer in the use of Mini Dental Implants for denture stabilisation.

At the core of his values as Principal Dentist of Padstow Dental Centre, Dr Kalis has a deep passion and dedication that is focused on delivering the best possible treatment and highest quality outcome for each patient. He thoroughly enjoys taking the time to listen to and understand every individual’s needs to provide customised solutions and relationship based care. He believes that delivering positive outcomes and experiences for our patients requires the backing of a well-trained team and continually invests in the ongoing development of the handpicked Padstow Dental support staff.

Dr Kalis is a member of the ADA and many other professional organisations to ensure he is always up to date with current dental procedures and protocols. He has been serving the Padstow area since 1998 after taking over the practice which was originally set up in the late 60’s.

Dr Kalis’ special interests lie in Cosmetic and Implant Dentistry but also provides the full spectrum of General Dentistry. He is genuinely devoted to the care and satisfaction of his patients' needs and draws no greater sense of joy or accomplishment than seeing the transformation that takes place within each person as their smile is restored. He believes a brilliant smile is an important asset and everybody deserves to look and feel their absolute best. In his down time, he loves nothing more than spending time with his family, keeping fit and getting out on the water for some relaxation or fishing.

Kristin Mundy

Kristin Gault - Oral health therapist

Kristin, our dedicated Oral Health Therapist is an integral member of the Padstow Dental Centre team and a key proponent in the delivery of our patients’ many preventive health care treatments. Kristin graduated from the University of Sydney in 2012 with a Bachelor of Oral Health Degree in which she spent 3 years studying and excelling in all aspects of the course prior to embarking with our practice. Alongside Dr Kalis, Kristin has continued on the path of ongoing professional and personal development and has been mentored to share in all the same philosophies and values. As a detailed and highly impassioned Oral Health Therapist she works collaboratively with Dr Kalis to provide you with an exceptional level of team based comprehensive care.

Under her Bachelor of Oral Health training which gives her the dual qualification of a Dental Hygienist and a Dental Therapist, she delivers a wide spectrum of supportive treatments which range from the 6 monthly preventive care visits, to the treatment of more serious gum disease issues along with all aspects of children’s dentistry. The ongoing dental health of our patients is extremely important which is why our continuing care program plays such an important role in helping achieve this.

Kristin is always ready to share her knowledge with you during your continuing care visit to ensure you are well informed about your dental health and how best to manage it. She places a high focus on prevention of oral disease and is passionate about creating individualised maintenance, homecare and product modalities to help every patient achieve optimal oral health.

In her free time, Kristin enjoys playing netball, looking after he dog and going camping on the South Coast. She frequently also delivers educational talks to our nearby schools as a community service.

Jorge De Nava

Jorge, our talented Oral Health Therapist is one of the newer additions into our team and has joined us to help meet the expanding needs of our patients. As a graduate of Charles Sturt University, he completed his Bachelor of Oral Health Degree in 2016 and in similar keeping to Kristin is dually qualified as an Oral Health Therapist and Hygienist. He brings in a great skillset and a whole lot of personality to supplement our focused tight knit team. He is extremely gentle, deeply caring, committed and shares all the key values our patients have come to know and trust over the years. He has a particular flair in the treatment of children and they seem to also share a natural affinity towards him. Jorge has excellent listening abilities and is able to naturally build relationships with trust and respect with all his patients. He works closely with Dr Kalis, Dr Blatchford and Kristin to provide the best quality dental care and treatment to patients of all age groups. Jorge is a member of the Dental Hygienists Association of Australia to ensure his dedication to providing services is always current and evidence-based.

To balance Jorge’s love for traveling and his passion for his career, he embarked on a rural care program after graduation to help remote communities across NSW and Victoria by promoting Oral Health and offering treatments deeply in need by these people, thereby also offering the opportunity to strengthen his already competitive experience in Children’s Preventative Dentistry.
