Dr. Olena Gill, R.Ac., DIHom, CCH, ND

If there is one word that would be a core theme in Dr. Olena Gill’s life, it would be Education.  Since the age of 8, Dr. Olena had wanted to be a doctor, but combined with her love of nature and farming family background, the road became a curvy one instead of a straight line.  Over the last 30 years, Dr. Olena achieved bachelor  degrees in both Music and Psychology from Queens University and Vancouver Island University.  She decided that natural medicine was far more interesting  so dipped her toe in the water and started to learn anything that interested her. Between 1994 and 2008, Dr. Olena amassed certifications, skills and training in well over 20 different holistic modalities – Reiki Master Teacher, Certified Aromatherapy, Certified Herbalist, and Colon Hydrotherapy, just to name a few.  You name it, it just might be on her wall!  In 2001, Dr. Olena took her education to another level, and received her Registered Acupuncturist (R.Ac.) license and has honed her skills in acupuncture, TCM Herbalism, tongue and pulse diagnosis.

Alongside all that learning, Dr. Olena opened up the first ever holistic multi-disciplinary clinic in Nanaimo – The Mind-Body Connection Centre – in 1994, practicing numerous modalities, as well as conducting workshops on natural health and personal development, herbal cooking classes, and botanical medicine making.  She finally had the opportunity to pursue her desire of being a doctor, and in 2014, successfully matriculated at the Boucher Institute of Naturopathic Medicine in Vancouver, BC. 

As of 2015, Dr. Olena is a licensed naturopathic doctor and is a member in good standing with BCNA, CAND, CNPBC, and CTCMA.  She has two naturopathic and holistic health clinics in Parksille, BC and on Gabriola Island, BC.  She currently integrates many different modalities such homeopathy, botanical medicine, energy work, nutritional and physical medicines, to best service her patients’ individualized needs.

Dr. Olena has wide-ranging experience treating many health conditions, and has a special interest in endocrine disorders, including thyroid health, diabetes and chronic autoimmune disorders.  She also enjoys working in the arena of palliative and end-life care.

When she’s not practicing in the clinic or teaching, you will most certainly find Dr. Olena working in her organic food and herb farm on Gabriola Island, growing and producing medicinal herbs, as well as continuously evolving her herbal body care product line called Sea-to-Sky Apothecary. Rounding out her life are her husband, 2 children, 3 cats and 3 dogs. Dr. Olena teaches Nutritional Literature Research and Anatomy and Physiology at the Nanaimo location of CSNN.


Dr. Crystal Hadikin, BSc. ND

She attended the University of Lethbridge for pre-med studies in Neuroscience and was a research assistant at the Canadian Centre of Behavioural Neuroscience. After completing her degree and honors thesis, Dr. Hadikin moved to Toronto to attend the Canadian College of Naturopathic Medicine and graduated in 2011.

Dr. Colleen Hartwick, N.D.

Dr. Hartwick has always had a passion for health and wellness and a fascination for the human body. Following her passion, she pursued post-secondary studies in the field of Kinesiology and Physical Education, as well as Psychology, at Wilfrid Laurier University. During her 3rd year of education, she was at a crossroads. Unsure of what path to take next for her career, she was serendipitously gifted with an opportunity to see a Naturopathic Doctor in her hometown of Peterborough, Ontario. She stumbled upon a career whose philosophy was in line with what she always thought medicine should be: treat the person, not the symptom, with safe and effective therapies and, most importantly, figure out why the person is unwell and address the underlying causes of disease. After her hour-long first visit, she found her path and purpose.

She then matriculated to the Canadian College of Naturopathic Medicine, in Toronto, Ontario, where she completed her four years of training as a Doctor of Naturopathic Medicine. During her formative education, she completed an externship in Beijing, China at a hospital of Traditional Chinese Medicine, where she honed pulse and tongue diagnostic skills. 

Upon successful completion of the diploma as Doctor of Naturopathic Medicine, she moved westward, toward the mountains and ocean, to start her practice with a focus on serving smaller communities that are often devoid of beneficial healthcare services. Dr. Hartwick’s four years of practice have unfolded in such a way that she fully addresses the whole person: mind, body and spirit where she integrates dietetics, herbal remedies, homeopathy, bach flowers and phytoembryotherapy to address, on an individual basis, the core imbalances for her patients.

In her spare time, she can be found at Robert Ostler park, practising yoga, in Strathcona Park conquering another hike, cycling down the roads of Quadra Island, climbing the crags at Crest Creek or Comox Lake or tending to her garden or in the kitchen, experimenting with her latest creation.

Dr. Hartwick presently teaches Pathology, Anatomy & Physiology, and Cellular Biology at CSNN Nanaimo.
