A passion for patient wellbeing

Carlton Dental Care has been serving families and individuals in Christchurch since 1963. While our facilities, technology and services have changed over time, our commitment to patient care and comfort is the same today as it was over sixty years ago.

In 2023, dentists Kelvin and Lydia Khoo purchased Carlton Dental Care from Rob Blackburne, who still works at the clinic. 


Kelvin Khoo

Principal Dentist

Kia ora! I hail from Malaysia. I pursued my dental education at the University of Otago and honed my skills in Invercargill and Christchurch after graduating in 2013. My wife and I lived in Invercargill for eight years before moving to the garden city which we now call home. Throughout my career I have mastered all aspects of dentistry and am particularly passionate about empowering patients with the knowledge they need to achieve good oral health. Witnessing the transformative power of a smile is incredibly rewarding for me. I make it a priority to stay updated with the latest technology and knowledge in dentistry to provide the best care possible. Beyond dentistry, you will find me savoring whisky, dabbling in amateur barista skills, and perfecting the art of grilling a succulent steak. Cheers to good health and a toothy grin!

Lydia Lim


I graduated from the University of Otago in 2014 and spent eight years working in Invercargill before moving to Ōtautahi with my family. Interestingly, my journey into dentistry was sparked by an encounter with a dentist who scolded me for apparent neglect in oral hygiene. Even though I had been diligently brushing my teeth twice daily, I was still struggling with bleeding gums. Determined to address the issue, I embarked on a journey into dentistry which quickly became my passion. I enjoy being part of a constantly evolving field. I am always eager to learn the latest techniques and cutting-edge technology to enhance my patients’ comfort and satisfaction. Outside of work I sing in our church choir, love travelling, and am always on the lookout for exciting activities to share with our two young daughters. 

Rob Blackburne


I wanted to be a dentist from a young age and have always been pleased with my choice of career. After achieving my Bachelor of Dental Surgery in 1981, I worked briefly in Mosgiel before moving to the UK. Admittedly, the move was prompted more by my interest in climbing than dentistry! But I stayed there, working for 12 years before heading home to New Zealand where I acquired Carlton Dental Care. Over my professional life I have especially loved meeting a variety of characters, assisting in interesting cases and pursuing my interest in sleep dentistry. I always try to give my patients a realistic appraisal of their needs and provide a comfortable, reassuring service. Outside of dentistry I enjoy walking, hunting, fishing and of course, climbing the beautiful mountains of the South Island.

Emma Hobbs

Patient Care Coordinator 

I started working as a dental assistant in 2001. Alongside my work I have pursued ongoing education in dentistry, earning my NZDA Dental Surgery Assistant Certificate in 2006, Invisalign Accreditation in 2008, Dento-facial Orthopaedics and Early Interceptive Orthodontics in 2009 (Sydney) and Dental Assistants Role in Supporting Complete Dentistry in 2016 (Florida). Over my career I’ve worked in a number of Kiwi communities including Thames, Auckland, Dunedin and now, Christchurch. For me, dentistry is all about people. I enjoy building relationships with colleagues and patients, and doing everything I can to provide a positive experience from start to finish. Beyond work, I volunteer for NZ Gifts of Love and Strength who provide care packages for youth affected by sexual harm. I also enjoy cooking (and eating!) and creative crafts.

Christy Immanuel

Dental Assistant

I am a registered dentist from India, having earned my Bachelor of Dental Surgery there in 2014. Since moving to Christchurch in 2017 I have been working as a dental assistant, caring for patients and their teeth. I joined Carlton Dental Care in 2024 and it is a pleasure to be part of such a friendly team delivering ‘best of the best’ treatment for every patient. My in-depth dental training means I can anticipate our dentists’ needs and help problem solve our patients’ issues. The variety in dentistry is endless and makes for an incredibly interesting career. On the weekends you are likely to find me spending time with my young daughter—shopping, exploring the park or tending our garden. We love to plant things together and watch them grow.

Radhika Mani

Dental Assistant

I have been working in dentistry in Christchurch for over five years, first as receptionist and now as a fully-fledged dental assistant. Here at Carlton Dental Care, I am focused on creating a welcoming environment for our patients and teaching them about their oral health. Everyone’s smile journey is different and I find it infinitely rewarding to see our patients walk out of our clinic feeling transformed. Teamwork is core to our approach and as professionals we all support each other to provide the very best care for our patients. Beyond work, I am very active at my church and often help out with activities and events. On the weekends I enjoy spending time with my family, taking my two daughters to the park and playing music together. 


Our approach is to take the fear out of dentistry for our patients. To that end, we have created a warm, welcoming environment where people feel at ease from the moment they walk in the door.

We are also focused on patient education, answering questions and explaining treatments in an easy-to-understand way so that people are empowered to care for their oral health at home. 

Our aim is to provide compassionate, comprehensive dental care

So you can enjoy long lasting dental well-being and the confidence of a healthy smile.
