Our Practitioners

Christina Camilleri
Founder & Director

Christina Camilleri is described as “one of the best kept secrets of the Okanagan”, well-known by reputation amongst health professionals in the field of nutrition, disordered eating/eating disorders. Many colleagues in various health disciplines around the province speak highly of Christina’s professional contribution and expertise. With over 30 years of clinical nutrition and behavioral counseling experience, extensive training and teaching opportunities, Christina’s vast knowledge and leadership is evident in all she does.

Christina graduated in 1987 from the University of Guelph with a Bachelor of Applied Science, Honors in Applied Human Nutrition. In 1988 she attended her clinical dietetic internship at Victoria Hospital, London, Ontario. During her internship, she focused on electives that included disordered eating, sports nutrition and cardiology. In June 1988, Christina was hired as a clinical dietitian for the Western Counties Wing War Veterans at Parkwood Hospital in London, Ontario. In working closely with this patient population, it was evident to Christina how the trauma of war correlated strongly with the veterans’ quality of life. As a clinical dietitian, her focus was to manage symptoms of illness through therapeutic meal plans. However, this was only scratching the surface. How do you support someone in trauma to make the necessary dietary changes to improve wellness and quality of life if they really don’t care or feel they have anything to live for?

As a new graduate and someone who had her own life experience with trauma, Christina’s energy and passion to help others sustain a love of life no matter the tragedies or circumstances, prompted her continued education towards behavioral counseling. At Parkwood Hospital, Christina worked closely with the multidisciplinary team. This team consisted of medical doctors and pastoral care, recreational and horticultural therapy, and nutritional support for prevention of illness, disease management and early intervention of disease. This unique treatment approach transferred into her private practice at the Fitness Forum, a high performance fitness facility where she worked with elite athletes, fitness enthusiasts, and individuals suffering from disordered eating and eating disorders.

Sports Nutrition has always been one of Christina’s passions, following naturally from her own enthusiasm for many sports both competitive and recreational. Christina is dedicated to helping athletes become the best that they can be in their sport, and she has often been a pivotal member of an athlete’s support team. She has worked with major league baseball players, CFL football players, junior hockey players, elite ski racers, junior varsity basketball, volleyball, soccer, rugby players, triathletes and more. To be a part of any athletes’ journey is a privilege and honor. The combination of nutritional and behavioral counseling is essential for every individual who pursues the athletic dream!

In 1991, Christina relocated from Ontario to the Okanagan Valley where she used her unique nutritional, behavioral counseling and educational background to support the development of disordered eating programs in both Kelowna and Vernon. Christina became a strong advocate for client centered care and professional development of multidisciplinary teams. She worked tirelessly to ensure that clients and their families could stay closer to home during their treatment process. Liaison with the multidisciplinary hospital team was necessary in developing inpatient eating disorder protocols for youth on pediatrics and adults on psychiatry. Christina’s drive to remain current with best practices through varied educational opportunities, committees, conferences, literature searches, media interviews, international presentations, mentoring and training opportunities contributed to some of the best multidisciplinary outpatient programs in the province.

Since 1992, as founder of Healthy Essentials, Christina’s private practice has remained under the radar, receiving referrals by reputation and word of mouth. The flexibility of being a business owner allowed Christina to enjoy the benefits of raising her family while fulfilling her desire to work in her specialized fields of practice both at her home office and in Vernon. In 2013, Christina resigned after 22 years as Coordinator of the CMHA (Canadian Mental Health Association) North Okanagan Eating Disorder Program. Christina will continue her leadership role in the community as Director of Healthy Essentials Clinic (HEC); an integrative team of experienced professionals who  provide person-centered care for clients and families who seek our unique services. Christina will continue to mentor, train, educate and consult with professionals to help lead the way in community health. She looks forward to growing and building Healthy Essentials Clinic into a larger community of care providers who will help to make her dream of serving all people who desire health, wellness and personal excellence a reality!

Nicole Whiddington
Pilates Instructor

Nicole found Pilates at age 17, after a car accident. Her chiropractor recommended core and spine  strengthening exercises. At the time she was living in a small town in Alberta where Pilates classes weren’t very common, she bought gaiam dvd’s and did workouts from her Mom’s living room. 

At the age of twenty, Nicole moved to Vancouver and discovered Pilates on the Reformer. Starting a regular Pilates regim was life changing, she noticed a big difference in the reduction of low back pain through strengthening core and spine and this was her first real introduction to the mind body connection.  A few years later the curiosity of teaching arose, when she discovered her inner teacher’s voice and a passion toward guidance others through movement. This inner voice was a calling for her to take a new direction into the path of health and wellness, which started off with a wonderful opportunity as Ambassador for Lululemon in 2007.

Throughout her teaching career of 20 years, Nicole has taught many different types of classes, from Aqua fit, TRX, Spin, Barre, Kickboxing, SUP, Bootcamp, Group fitness, Yoga, Mat Pilates & recently Pilates Reformer.

Why work for HEC: “I was first drawn to the clinic a couple years ago, while taking private pilates classes. I absolutely loved the warm, welcoming atmosphere in the professional setting. I am thrilled to be part of this Multidisciplinary team, offering a forward thinking approach to Health care. My beliefs in Holistic Care, align with the vision of HEC and I am honoured to teach Pilates as a practice of movement for clients among all the services offered by practitioners at HEC.”
