I was born in South Africa and completed my medical degree in Cape Town.

I have been working at Rolleston Medical Centre since 2009 and live with my husband and two children in the Selwyn district. I also work as a medical educator for Pegasus Health.

I moved from Sri Lanka to New Zealand in 2005. After working for a few years in hospital medicine, I completed my GP training and have been working as a GP in Selwyn of the past 10 years.   I enjoy all aspects of GP practice, and have a special interest in Women’s Health, lactational medicine, child health and promoting healthy lifestyles.  When not at work, I enjoy spending time with my family , cooking, exploring nature and painting.

Dr Joanna Dixon

I emigrated to NZ 12 years ago from Kent in UK when my Kiwi husband got a job at Lincoln University. I have been working as a GP and living in the Selwyn area with my husband and 3 children since. I enjoy the varied challenges of being a GP, with special interests in women’s health (insert intrauterine coil devices), child health and care of the elderly.

Dr Peter Ryan

I was raised in the Manawatu as a Turbos and Hurricanes supporter, and now have 3 proud Cantabrian children. I bring a wide range of life experience:  I’ve been a farm worker, builder’s labourer, finished an Agricultural Science degree, youth work, travelled, then medical school. I have a personal interest in skin cancer and use this both as a GP and also to run the Selwyn Skin Cancer Practice.

Dr Philippe Bierny

I’m a recent New Zealand transplant from Arizona. I have a particular interest in preventive health care and health education. I’ve loved the move from the desert to the coast. I get out to the mountains for a tramp every chance I get, and travel when time permits. I also love languages. I speak French and Spanish and a little Chinese, and I’m always trying to learn some new words in Māori and Kiwi!

Dr Amanda Parkin

I graduated from Otago Medical School, then worked in various places around New Zealand before returning home more than 20 years ago to Canterbury, for the most part working in the Selwyn District. When not avoiding cooking, I appreciate the high quality of life living in a semi-rural district, and enjoy the variety of challenges and interactions within general practice.

Dr Chivala Heal

I was born and raised in Dunedin and graduated from Otago Medical School.  Before my career as a doctor I worked in Public Health.  I spent my first few postgraduate years working at Christchurch Hospital working in a number of different specialities including General Medicine, General Surgery and Older Persons Health. I live locally in Selwyn with my husband who is in the NZ Army and our young son.  When I am not working I enjoy spending time with my family, baking and cake decorating.

Dr Chantell McKee

I was born in Pennsylvania and after living in various parts of 

the US and traveling as much of the world as I could, I moved 

to New Zealand with my Kiwi husband and two gorgeous 

young children. I have served in the US Air Force as a 

physician which has fed my interest in sports medicine. I also 

enjoy women’s health and reproductive medicine. In my 

personal time, I enjoy various arts and crafts, including 

abstract painting, crochet, wood working and sewing. I live in 

Rolleston with my family, including my mini schnauzer and 

African Grey parrot.
