Surrounded by a dedicated team, which combined has a total of over 200 years of clinical experience, Jim would like to continue the longstanding Harmony dental tradition of providing a caring environment with a strong focus on prevention of dental problems.

Having seen and treated many various dental problems in country practice, Jim encourages all his patients to work towards dental prevention as being the ultimate goal for their future.

As a father of four, Jim would also like to ensure that all patients, particularly children grow up with positive dental experiences .

Having triplet girls and a son, Jim, in his free time enjoys relaxing and spending time with his family.
