Dr David Sweeney

David has an innate ability to make people feel instantly comfortable and at ease. Most of David’s patients have been continuously seeing him for over 10 years, following him from other practices and often travelling more than an hour to see him.

David is a great talker, and that is part of his charm. He can often explain what is going on in terms everybody can understand, but more often than not he is telling stories about his eccentric family to make people laugh and forget they are at the dentist. It is surprising the amount of David’s patients that fall asleep while he is working. This is a true reflection of just how gentle he is, not how boring he is! David takes snoring as a compliment.

Aside from being a practicing dentist, David lectures nationally and internationally and has held faculty positions with the University of Sydney and Charles Sturt University.

Happily settling back into her hometown, Jenny, a natural problem solver utilises her gentle touch to tackle any situation with a holistic approach. With a family of her own, she understands the intricacies of working with children and aims to help every family member achieve a healthy mouth. Jenny has a genuine desire to help people and with her gentle touch and calming energy.

When Jenny is not at work she can be found at Bondi with her kids, reconnecting with Sydney, her home she has missed for many years.

Dr Leah Pelton

Originally from Canada, Leah moved to Australia in search of warmer weather.  However, she ended up with a whole lot more – An Australian dental degree, husband, son and daughter! Leah and her Aussie family have made their home in Sydney’s Inner West.

One of the most common questions Leah gets asked is “Why dentistry?”  Leah likes to think of dentistry as arts and crafts, but with teeth!  Every time she works on a tooth she sees it as a mini makeover- tailored to each tooth and every individual. Leah always takes the time to ensure you understand your dental treatment and feel as comfortable as possible.  Leah is passionate about helping you maintain your natural smile and loves to educate people and help them avoid fillings and other dental work. However, if you do need something done, Leah is dedicated to creating great looking and long lasting outcomes. 

Leah truly is your local dentist- lives in the area, works in the area and when she’s not working on your smile, she can be found being a busy mum to her son and daughter, or in the kitchen creating and decorating outstanding cakes for all occasions.
