Meet the Physicians at Linden & Arc Vitality Institute


Dr. Lynne Murfin

Founder and Medical Director


Linden & Arc Arc Vitality Institute's Founder Dr. Lynne Murfin

“Passionate science coupled with transformative care has always been my driver. There is nothing more fulfilling than being able to change the arc of a patient’s life.” – Dr. Lynne Murfin


What is the Linden & Arc Vitality Institute and why do so many people feel, after years of struggle, that they finally found help?


Dr. Lynne Murfin has gained strength, and deep understanding, and built a vast knowledge of Functional Medicine over 34 years of practice. She has found great success achieving healing results in her practice at Lynne Murfin MD. Linden & Arc Vitality Institute was born, out of tremendous frustration with the array of  unused tools in the toolbox of medical science.  Tools that could address the root cause of health issues by understanding what triggered them in the first place.


Dr. Murfin talks often of how  the damp, musty basement, that spider bite years ago, or eating certain seafood on that Caribbean cruise could be the reason for the downward spiral in a patients health. This can manifest as fatigue, chronic pain, and other deliberating symptoms. These symptoms can be remedied with relatively straightforward interventions.


Crystallization that Functional Medicine is the future of health care – is the practical interface for systems biology in clinical care – is pivotal to why Dr. Murfin transitioned from her clinic to create the Institute. The knowledge that the body is a biological system, and everything is connected, is how we transform Medicine from treating symptoms to uncovering and treating the root causes. Often, it’s the system interface of Gut-Brain-Immune needing review. Something as simple as an undetected food allergy can create havoc in the permeability of the gut lining with immune system upregulation in the gut.  This eventually culminates in blood brain barrier permeability with constipation and bloating. It is then accompanied by brain fog, memory loss and headache. This too can be addressed and healed.


The same symptoms often have different root causes and so treatment cannot be one size fits all.  For example, if you have a headache there are multiple possible root causes such as nutrient depletion (e.g. low magnesium and low coenzyme Q10) or possible gut symptoms. Taking Tylenol or Advil rather than addressing the root cause will not solve your issues.


Through finding exceptional doctors who get what Functional Medicine truly is, and mentoring them, Linden & Arc was born. Dr. Murfin and her team are here to help those who are tired of battling persistent health challenges while struggling to get the medical support and treatment they need. Dr. Murfin believes that everyone deserves the highest level of wellbeing and will stop at nothing to heal her patients.


Dr. Michelle Van Der Westhuizen

Functional Medicine Physician


Linden & Arc Arc Vitality Institute's Dr. Michelle Van Der Westhuizen

“My passion for uncovering the root causes of illness goes deep. I have committed to a lifelong journey of learning about all levels of health so that I can better serve my patients. I believe that true healing is possible for everyone, and I hope to empower and educate patients to take control over their own health.”– Dr. Michelle Van Der Westhuizen


Dr. Michelle Van Der Westhuizen, one of Linden & Arc Vitality Institutes Functional Medicine Physician’s, has a passion for helping people uncover the root cause of their illness. Though everyone’s healing journey is unique, Dr. Van Der Westhuizen trusts that true healing is possible for everyone. She feels that medicine is an art that requires more than just textbooks and data, functional medicine requires both the patient and the practitioner’s innate wisdom.


Her favorite question to ask is “But why?”

She understands that your current health tells a story and that when you have symptoms of disease, your body is already out of balance. She believes that we should not have to settle for anything other than our most vital self and that her job is to figure out how to put you back on track.


Dr. Michelle Van Der Westhuizen’s goal at Linden and Arc Vitality institute is to contribute to root cause medicine by studying and exploring the physical, emotional, mental, intuitive, spiritual, and energetic aspects of health so that she can better serve her patients. Dr. Michelle is Canada’s leading Chronic Inflammatory Response Syndrome (CIRS) physician and often lectures and publishes on the many facets of CIRS.
