Through my years as a dental hygienist, I saw how many patients were struggling with breathing and airway-related concerns, and I wanted to find ways to help. As a parent, I noticed signs of airway and breathing difficulties in my own three children. Looking for answers, I began to look at breathing and muscle function alongside conventional medical and dental care. That was a lightbulb moment, and I haven’t looked back.
Functional airway health has become my passion.

Harmony- The balance, peace and sense of wholeness, where various factors align and support one another
Orofacial: Related to the mouth and face.
Myology: Restoring correct function of muscles through re-training muscle therapy.
Harmony was born out of a desire to improve people’s lives.
After decades of clinical experience as a dental hygienist, it was time to expand my acquired skills and put them into practice in an interactive way, without the limitations of the setting of clinical dental practice.
Curiosity and continuing education, have led me in this path to promote wellness and health improvement by providing a comprehensive service, that will positively impact people’s lives. We often hear “the eyes are the windows of the soul” I have come to understand that the mouth provides us a view into the health of our whole body.
Healthy breathing is the aim
I am dedicated to improving wellness by identifying airway issues in children. Early interventions are key to prevent the detrimental effects of improper breathing.
Being able to identify narrow palates, tongue ties and teeth crowding as early as possible can make a huge difference in treatment modalities. Helping to eradicate habits that lead to palatal malformation such as thumb sucking, nail biting, extended attachment to pacifiers are also best treated early.
Adults with airway issues such as snoring and sleep apnea, jaw joint issues causing tension headaches (and more!) can also improve their health by undertaking a orofacial myology program.
OMT can help with strengthening weakened orofacial musculature caused by mouth breathing, which can affect dental health by causing and array of issues such as dry mouth, gingivitis, increased buildup of tartar and likelihood of increasing risk of gum disease.
Mouth breathing has been associated with dry mouth, plaque build-up and gum inflammation, and may be a factor in tooth decay risk for some people. If you’re concerned about your oral health, it is important to have regular dental examinations.

The four goals of OMT are:
Establish nasal breathing
Restore adequate lip seal
Create proper tongue posture
Correct swallowing pattern
Making the whole body connection for better health outcomes
As an orofacial myologist, I aim to grow relationships with an array of skilled airway conscious health practitioners. ENT’s, dentists, orthodontists, chiropractors and osteopaths to name a few, an integrative approach can have a significant impact in achieving these wellness and health goals.
I believe functional, airway focused dentistry and medicine are the way to go forward to improve overall health and wellbeing, a holistic approach based on solid, science-based therapeutic interventions that will ensure the health of future generations.
The human body isn’t made up of separate compartments, we are a wonderful network of intricately connected systems and likewise, the health professionals treating you and your family should be aiming to work together to help you achieve optimal health outcomes.
