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.

Jorge De Nava (Oral Health Therapist)

Jorge, our smiling and talented Oral Health Therapist is an integral member of the Padstow Dental Centre team and a key player in the delivery of our dedicated health care. He plays a very important  role in looking after much of the ongoing preventive care treatments for all our patients and all the direct needs of our younger patients. He works hand in hand with Dr Kalis to ensure our patients receive the most thorough treatment possible. He joined our practice in 2018 and has been mentored extensively by Dr Kalis to fully appreciate the needs of our patients and the ideals of optimal health care delivery in accordance with our practice philosophy and values.

Jorge is a graduate of Charles Sturt University, having completed his Bachelor of Oral Health Degree in 2016 and is dually qualified as an Oral Health Therapist and Hygienist. This gives him quite a broad scope to cover very many of our patients’ health needs. For the first two years after graduation he embarked on a rural care program, providing dental care and oral health promotion to underprivileged communities across outback NSW and Victoria for many people in deep need. Alongside Dr Kalis, Jorge has continued on the path of ongoing professional and personal development and as a focused and highly impassioned Oral Health Therapist he works collaboratively with Dr Kalis to provide you with an exceptional level of team based comprehensive care.

He 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.

He brings in a great skillset and a whole lot of personality to the mix. 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 his gentle eagerness to please. Jorge is a member of the Dental Hygienists Association of Australia to ensure his dedication to providing services is always current and evidence-based.

When not working, Jorge likes to travel and spend time with friends and as much as he tries to switch off, he’s always looking for ways to improve his skills and experiences for our patients.
