London: Faculty

Joni Yungblut, R.H.N. – Licenced Branch Manager

Joni YungblutJoni Yungblut – Registered Holistic Nutritionist™, Organic Master Gardener and Personal Trainer – is the Licensed Branch Manager of the London Branch of CSNN and is affectionately called “Mother Dove” by her students for her heartfelt (and silly) analogy of setting her students free to change the world!

Growing up in rural Ontario, Joni developed an interest for the outdoors and exploring nature early on. Already stubborn and headstrong, she became a baseball fan and fine-tuned her skills to keep up with her 2 older brothers – and has won many team championships and personal sports awards over the years. She is an avid fitness enthusiast, participating in competitive baseball and beach volleyball year round.

Joni attended Conestoga College for Police Foundations, but due to poor eyesight, was unable to get into policing. So she opted for a career as a Private Investigator and worked mainly in the field of white-collar crime and fraud. Although the work was fascinating, it did not fulfill her personally.

At 16, Joni lost her father to cancer. With her own diagnosis of IBS and ongoing struggles to manage the disorder, she was concerned for her future health…until she walked into a health food store one day and asked for help. The advice she was given changed the course of her life as she discovered a new way to restore her body through holistic nutrition, lifestyle changes, and a positive shift in mental thinking. She was told about the Canadian School of Natural Nutrition and hasn’t looked back.

Joni knew it was time to make a career change – one that would fulfill her spiritually and speak to her need of helping others. She graduated from CSNN in 2004 with Honours and immediately started her nutrition practice. She worked daily with her clients until she opened the London Branch in 2006.

Joni has a wide range of knowledge on nutrition, athletic performance and injuries, weight loss/gain, cancer, hormonal imbalances, vitamins and minerals, natural healing alternatives, and herbal medicine. She has completed additional education on Natural Health Care for Pets and has completed the Certified Master Organic Gardener certification.  Joni has a hobby farm where she grows her own organic food and raises free-range heritage breed chickens. She is a published author and proud to be part of a school that continually thrives to bring the best education to their students and opportunities for graduates, and loves going to work every day to see the excitement on the students’ faces as they learn.

You’ll often find Joni teaching Fundamentals of Business, Sports Nutrition, Nutrition Literature Research, as well as numerous practicals. She also works on writing projects and is happy to report she now has 20/20 vision.

Heather Bulckaert, B.A., R.H.N.

Heather BulckaertHeather has always been passionate about what she eats. As a child, she was a picky eater and as a teen, she struggled to find the balance between food and body image. After years of under eating, over exercising and always feeling mentally overwhelmed, she was able to identify the important connection between the mind and the body. This holistic realization led her to complete her BA in Psychology at the University of Windsor.

After years in the corporate world, Heather was driven to feed her passion for nutrition and earned the R.H.N. designation from CSNN in 2010. The experience and the education have been life-changing. Heather continues to work in Program Management, is a Registered Holistic Nutritionist™ professional and a teacher at CSNN in London, ON, teaching Fundamentals of Nutrition, Pediatric Nutrition, and Preventative Nutrition. She loves watching the transformation in the lives of her students.

Now, a mother of two little girls, having the knowledge to raise them with optimal nutrition choices and a healthy body image is the greatest benefit. Her husband has been her nutritional “guinea pig” for years; suffering from IBS throughout life and is now symptom-free. The health changes in herself, her clients and her husband are a true testament to the power of food.

Heather loves to be with her family, go for a good run (mental therapy) and experiment to create new, healthy recipes. She is passionate about continuously educating people so that they can live their best life.

Roxanna Churko, BSc Kin, CEP, R.H.N.

Roxanna ChurkoRoxanna has been passionate about health, wellness, and fitness since as long as she can remember. Knowing this from such an early age helped her determine her education path leading to a Bachelor of Science in Kinesiology. She then became associated with the Canadian Society of Exercise Physiology, getting her designation as a Certified Exercise Physiologist. With this, she started in the fitness industry working at colleges and universities, and later with private businesses and corporations, in their fitness and wellness programs.

Holistic nutrition came into effect after Roxanna had some health scares herself which had no answers through Western Medicine. A friend of hers mentioned the program through CSNN which she sought out as she felt it would be a good fit not only for her personally but professionally as well. Roxanna graduated with honours from the Canadian School of Natural Nutrition in Calgary in 2010 and has continued taking the advanced workshops as available.

Roxanna moved to Ontario in 2014 and has founded Churko Health Consulting in Woodstock. She encompasses her education and experience working with elite athletes and the general public and has been a major role model for women in girls in the community to realize their optimal potential in health and in life. Her belief is you can do anything you put your mind to by seeking out a network of professionals in the area you want to succeed in.
