She continued to work as a dental hygienist in both the regular and territorial forces of the army up until 2003, gaining valuable experience in a wide scope of hygiene practice.

Being involved in civil aid projects providing dental treatment for people who were disadvantaged or living in isolated areas allowed exposure to extremes in treatment requirements not often seen in private practice. She also spent some time treating NZ personnel in Singapore and participated in a Mutual Aid Programme (MAP) instructing at the Navy dental school in Jakarta, Indonesia. The experience gained through the military has proved to be of considerable benefit to my patients.

She offers each patient the best advice, and all options for their individual needs are fully discussed. She has the training and experience to provide sound treatment for advanced gum problems and accepts referrals for treatment of people who may not be able to afford or need specialist care.
