Dr Yinan (Nana) Zhang, Bachelor of Dental Surgery with Honours, Otago


Nana grew up in the Mighty Manawatu and completed her Bachelor of Dental surgery in Dunedin and worked back home as a dentist before the big move to Taranaki.

Nana is excited to connect with the people in Stratford, which has a familiar vibe to Feilding, where her family lives.

In her spare time Nana likes to look after the animals on her parents' lifestyle block - her border collie Conan, chickens and lambs. She also enjoys playing the guitar, drawing and going on road trips to go skiing and visit friends. Looking for antiques and vintage collectables is a hobby which started with a Brownie film camera, Nana loves going to markets and shops to eye out these hidden treasures.

Nana looks forward to joining the team at Stratford dental and working along side MaryAnne, and getting to know the community.
