Dr Karu continues to undertake additional education and training to ensure he is providing the best possible care for all his patients.

Passion for Crafting Beautiful Smiles in Epping

Dr Karu is passionate about dentistry and ensuring the wellbeing of his patients! With his decades of experience in the dental industry and the help of his incredible team, his goals include:

Outside of Work

On top of ensuring the wellbeing of his patients, Dr Karu believes in helping the community.


"I strongly value the importance of family health, being married with two adult children myself, as well as helping the community around me. I've had the privilege of supporting both local and international communities." 

Dr Karu has been a Rotarian with the Epping Rotary Club since 1988. As a Rotary Executive, general member and personally, he has been involved with raising funds and procuring donations to aid many people in need not only in Australia, but also Papua New Guinea, Fiji, Vanuatu, Sri Lanka, Mongolia, and Napal. 

"Locally, I have the pleasure of continuing to support charities and organisations such as the Ronald McDonald House, Women's Refuges, the Alzheimer Foundation and our local Schools."

Dr. Vidhi Somaiya

Principal Dentist

Our ray of sunshine. Dr. Vidhi has a variety of experiences, ranging from hospital & private clinics across remote and metropolitan areas in NT, Queensland, Tasmania and back home in Sydney! She values conservative, minimally invasive care, with a philosophy that aims to preserve and maintain your natural teeth for life.

She graduated from James Cook University in 2019 with the Bachelor of Dental Surgery, and continued further training with the Royal Australasian College of Dental Surgeons, receiving multiple awards.

Dr Vidhi thrives off using cutting-edge technologies and evidence-based practices to achieve beautiful results & happy smiles. Her warm personality is a natural winner with all our patients, especially children!

When she isn't thinking about teeth, Dr. Vidhi loves exploring the great outdoors. You might find her hiking in nature or spending time with family. She has a sincere love for music and travel and getting artistic with food. She's never too far away from the dental word- because her husband is also a specialist dentist!
