Dr. Tarn de Ridder


I grew up rurally in Whangarei, spending most of my teenage years horsing around which inevitably leads to falls and injuries. My first experience with a chiropractor came after one of these falls, and I couldn’t believe how much better I felt and could function! It was only a matter of time before I enrolled to study Chiropractic.

I graduated from New Zealand College of Chiropractic in 2014 with the Academic Excellence award and the Business Award. Since graduating I’ve spent a couple of years working in Wellington, undergone post-graduate studies in pediatrics and Sacro-Occipital technique, and moved back to Whangarei to enjoy our little slice of paradise in Maungatapere.

Being in the winterless North means we can spend more time with our family, enjoy beaching, boating and fishing, and have enough space for some animals and a horse!

Chiropractic Assistant

Lisa’s background is rather diverse.  Originally from Takapuna, Lisa was educated in Dunedin where she attended Otago Polytechnic obtaining Trade Certificate in Shorthand Typing. Then with her parents moving to Whangarei Lisa also moved north where she married and had her two children. Lisa worked at the Whangarei Courts as a Shorthand Typist in the 1980s, which was an extremely interesting role.  Over the years Lisa has worked within large blue chip Accountancy and Law firms in both Dunedin and Auckland Cities, with the Bay of Plenty Regional Council in Whakatane, Real Estate in Whakatane and Ohope. Her final move is back to Whangarei after 32 years.  Lisa now has 3 grandsons in Whakatane and family in Whangarei.  She loves to visit the family, run, walk, garden, keep bees, renovate and enjoys her and her husband’s “muscle car” when doing long road trips south along with her dog Bella.
