About Us


Our Founder

Kathleen McDonald holds a BScN, MN, NP in Adult Medicine and is the founder of Precision Health Centre (PHC) which utilizes the latest technology in diagnostics, paired with highly advanced wellness programs, to optimize and take your health to the next level. The individual health of EACH client is her and our passion. Kathleen completed her training at both University California San Francisco (UCSF) and University of Toronto.  Her work experience includes top academic centres such as University Health Network with the Peter Munk Cardiac Surgery Team, University of Michigan Medical Centre, University of California San Francisco, and Sunnybrook Trauma Centre. Optimization of Human Health & Performance requires us to both incorporate the tenants of conventional medicine with the new cutting edge and targeted metrics to effectively promote a healthy lifestyle and optimize physical performance. 


Prior to opening her own practise, Kathleen had been working 50 - 60 hour work weeks and started to experience chronic fatigue, low vitality, and other health issues. Discouraged, after seeing her Family Doctor for an all to  brief assessment, and whom discredited her concerns, as she had 'normal' blood tests results, (she later learned that her labs were straddling the low end of normal), which were performed under the traditional umbrella of chronic fatigue, (CBC, iron, and limited thyroid studies), she then visited a Functional Medicine clinic and couldn't believe how much better she started to feel and how much more energy she had.  Realizing this, it gave her back her hope and sparked her future research and passion into understanding how to curate the latest research in age management medicine and optimize the body so as to maintain this level of energy & vitality. 

Kathleen's motivation to help others is very tangible during one's treatment course,  and you'll also frequently see updates on her different missionary adventures while visiting the clinic. Her passion for attaining this heightened level of health, not only for herself & her active lifestyle, which includes cycling, and 70.3 Ironman, also extends to her clients. This has driven her to research niche regenerative & health optimization therapies, right down to a cellular level, in order to provide powerful results. 


When I hear people say; “I am just getting older, I respond that our bodies are brilliantly designed and if optimized, based on scientific principles, we can then look, feel and function on a level we hold as an ideal in our minds. It is attainable and possible! “

Bryan Hardy, CNP

"Bryan Hardy is a Holistic Nutritionist (CNP) and Integrative Wellness Coach who specializes in optimizing digestive function, balancing blood sugar, and reducing inflammation so that the body can recover and adapt to the stresses of modern life. He is a registered member with the Canadian Association of Natural Nutritional Practitioners and graduated from the Institute of Holistic Nutrition with first class Honours in early 2015.

His journey into wellness began after suffering a ruptured appendix which nearly killed him at age 18 and ultimately invited him to refocus his life in order to learn how to be a healthy and happy human being. This journey has brought him to where he is now which is working as a clinical nutritionist, wellness advisor and public speaker. He is a calm, kind, and big thinking individual who sees great potential in those around him and works to assist in the process of personal transformation and empowerment.

Bryan’s strength is in breaking down complex concepts around health, nutrition and wellness into easy to digest chunks that foster a deeper awareness and connection to the body and to the earth of which our bodies are made. He is also a great cook who can teach you how to make healthy eating delicious and time efficient.

He recognizes that the chronic mental and physical health issues that are plaguing our population today are largely a result of our lifestyles and diets and as such works to help create new habits and assist clients as they move into a sustainable, empowered and health promoting direction.”
