Our Dentists

Gus Ariaens

After graduating in 2008, I worked as part of the Maxillofacial Team at Waikato Hospital for 2 years – an experience that helped me develop my dentistry skills, especially in the area of non-specialist oral surgery. I worked for a year at Hillcrest Dental Centre before transferring to Tauranga for 2 years for my wife's medical training. We returned to Hamilton at the end of 2013 and became a partner of the dental practice in 2016 and in 2019 took over full ownership of the practice.

I enjoy meeting new people and providing all aspects of dental treatment with a minimum of stress. I offer IV sedation for my patients who wish it, whether it be for wisdom tooth removal or general dentistry.

I moved to New Zealand from the Netherlands in 1995 when I was 10 years old and am still able to speak Dutch. During my time off I like spending time with my wife, Caroline, and our three children, Charlotte, Jack and Emily.

Celeste Lim

I completed my Bachelor of Dental Surgery in University of Otago in 2020 and moved up to Hamilton after.

Being from Malaysia, a melting pot of cultures, I enjoy meeting new people and connecting with each patient.

I strive to maintain a gentle manner throughout the entire dental experience. Dental anxiety is a common concern, and that's why I'm dedicated to creating a comfortable environment for every visitor to the clinic, transforming dental visits into positive, stress-free experiences.

Outside of work, I practise yoga for my fitness and mental well-being. I also enjoy exploring the region through hikes.

Karyn Taylor

I had been Owner Practitioner at Hillcrest Dental Centre since 1997 until Gus Ariaens took over the Owner Practitioner role in 2019. I practice all aspects of dentistry with a particular interest in Restorative Dentistry. As one of the senior dentists at the practice, I have been taking care of the oral health of many of our long-standing, loyal patients of Hillcrest Dental Centre and their families.

I am a keen quilter and triathlete and was a Past President of the Waikato Bay of Plenty Branch of the NZ Dental Association.

Karyn is not accepting new patients.

Steven Pawley

I first came to Hillcrest Dental Centre in 1988 and was Owner Practitioner from 1989 until selling the practice in 2019 to Gus Ariaens.

I have practiced a wide range of family dentistry over this period and completed a Post Graduate Diploma in Periodontology, with distinction, in 2000. My attention is focused on the treatment of Periodontal (Gum) disease and minor Oral Surgery with IV Sedation.

I am a keen cyclist, and have competed in recent years at the World Amateur Cycling Champs in Europe. I am also currently serving as President of the Hamilton City Cycling Club.

Steven sees patients referred by their dentist for periodontal treatment. He is not available for general dentistry.

Janet Yen

Originally from Taiwan, I moved to Hamilton in 1999 & can still speak fluent Mandarin as well as English. I graduated from University of Otago with my Dental degree in 2010. 

I previously worked at Palmerston North Hospital before joining Hillcrest Dental Centre in 2013.

I enjoy all aspects of general dentistry particularly in restorative & preventative aspects. I strive to create a calm & respectful environment for my patients to help them make an informed decision about their oral health.

I have  volunteered with organisations like YWAM Ships Aotearoa, Trinity Koha mobile dental clinics, NZDA free dental days, Marine Reach Fiji & East Meets West Foundation in Vietnam to provide free essential dental services to theses underserved communities.

Outside of work I enjoy practising Kendo (Japanese martial arts), playing the piano, singing & participating in local church activities.

Sonam Bansal

I graduated in North India in 2005 and worked there as a dentist until 2007 before moving to New Zealand.

While going through the registration process in New Zealand I worked as a dental assistant at the Oral and Maxillofacial Surgery department at Waikato Hospital, gaining valuable experience working with senior consultant maxillofacial surgeons. I gained registration in 2011 and started working at Hillcrest Dental Centre in May 2012 as a general dentist.

I am passionate about preventative dental care and patient education. I also have an interest in all aspects of general practice including cosmetic, restorative dentistry and endodontics. I am a gentle, caring and sensitive practitioner who adheres to the highest standard of care and treatment. I can speak fluently in English, Hindi and Punjabi.

Outside of work I enjoy travelling, reading, baking and spending time with family. I am married to Nitin and have two beautiful daughters Ananya and Niyati.
