Optimizing Human Performance


Medicine is the art, science, and practice of caring for a patient and managing the diagnosis, prognosis, prevention, treatment or palliation of their injury or disease. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness


  • The objective of optimal human performance, resilience and healthy lifespan
  • Beginning with the fundamentals of nutrition and lifestyle
  • Harmonizing clinical experience with statistical medical research and client goals
  • Individualizing diagnosis and treatment
  • Making informed risk-reward ratio health choices
  • Superseding reductionism with coordination between medicine & exercise, mainstream and complementary medicine
  • New solutions to new problems without losing sight of accumulated human experience & wisdom
  • The application of neuro-psycho-physiology
  • Using objectivity to conquer bias and identify disinformation
  • Leveraging technology while maintaining privacy
Personalized medicine clinical services suitable for the curious who question:


  • would I regret growing old without exploring the beauty and strength of which my body is capable?
  • what if I was calmer, stronger, faster and with more acuity, for myself and my loved ones?
  • does it matter what I eat?
  • is it all in the genes, or does environment impact upon expression?
  • is health a spectator sport, or is it for me?
  • can there be health without purpose?
  • if nothing stood in my way, what would I wish for?
  • if everything external were to remain unchanged, what would I prioritize?
  • how do I work out what food and health questions to ask?
  • should I take a grain of R.I.C.E. with a pinch of salt?
  • is medicine healing, or is medicine treating symptoms?
  • does it matter that the medical ritual and physical examination are in decline?
  • are anatomy, physiology and biochemistry as important for health as pharmacology and surgery?
  • is allopathic medicine destined to be a simplistic symptom-pill algorithm?
  • what motivations and mental models underlie scientific and expert advice?
  • is the goal of public health treatment or cure?



Adults aged 20+.  While acknowledging the role of acute care & emergency medicine, the clinic focus is health prior to the acute stage, with the fundamental that individual choices significantly influence age and disease.

The clients:


  • have initial test results from a GP and have considered 8 Things to do before seeing a Functional MD
  • are self-motivated to modify lifestyle & nutritional habits to take advantage of new information
  • are optimizing their body with movement and exercise
  • are seen in an appropriately relaxed & personal clinical setting
  • use an online Patient Portal (or are able to get family to assist)
  • seek to navigate conflicting health information and medical system silos
  • seek to identify & address underlying causes
  • seek to take advantage of the latest medical research & capabilities
  • wish to be treated as more than a number
  • understand that clients and registered doctors operate in a regulatory environment in which the doctor is held liable by authorities
  • are discharged 2 years after the last visit
The clinic:


  • is focused on understanding underlying causes, to avoid quick fixes daisy chaining the next trigger, and further restriction of diet and lifestyle
  • works with all diets and lifestyles and is not beholden to any one mental model or medical modality
  • does not receive state funding or profit from the sale of supplements
  • cannot know in advance what treatment costs will be
  • looks to re-frame past medical experiences with impartial options, from which the client may make their own choices
  • uses a personalized-medicine EHR to create the clinical framework for accuracy and managing medical risk
  • prefers clinical visits to telehealth where possible
  • eschews google, facebook and remarketing intrusions to value individual privacy and self determination


What diagnoses does the clinic treat?

  • Autoimmune Conditions
  • Depression
  • Hormonal Issues
  • Digestive Disorders
  • Allergies
  • Asthma
  • Menopause symptoms
  • Headache and Migraine
  • Fatigue, Chronic Fatigue Syndrome, Slow metabolism, Low Energy

  • Diabetes
  • Arthritis
  • Memory and Concentration loss
  • Accelerated Ageing
  • Obesity/Weight gain
  • Cognitive decline, Head Injuries

What is involved?

  • Investigation of:

    • Biochemical & BioPhysical: addressing imbalances & deficiencies

    • Biomechanical: from physical imbalances through to surgical options

    • Neuro-emotional: from unconscious programming through to electron/ion communication of neurons

  • Advanced personalized, functional and genetic testing

  • Targeted lifestyle and advanced nutritional treatment

  • Review of brain health and neuroplasticity
  • Review of medication

  • Advanced prescriptions, supplementation, herbals (e.g. GMP, TGA, USP certified pharmaceutical grade)

    • Supplements are unregulated natural medicinal compounds, usually with side-benefits rather than side-effects

    • Functional doctors are qualified and experienced in the use of supplementation to address imbalances signposted by advanced testing

  • Referrals to specialists where appropriate
  • A documented wellness plan updated after each consultation

  • The digitalhealth app is intended to combine wearable data with clinical workup for improved collaboration


What is an example?

A client presents with sleep & energy issues. Diagnosis & treatment might include:

  • Clinical presentation and investigation (e.g. blood tests) might suggest hormonal or metabolic problems e.g. thyroid, dopamine, insulin, estrogen or testosterone imbalances.

  • Consideration of progress/relief via direct prescription/supplementation, or indirectly via a related pathway.

  • Evaluation of nutrition and gut health.
  • Deduction of whether a deficiency or imbalance is due to a hormone not being produced, whether it’s not being used effectively (blocked), or whether it is not being metabolized optimally.

    • As well as blood tests, the combination of an OAT, DUTCH or Gene test might help to clarify e.g. from a urine test, it may be possible to work out whether an iodine insufficiency is contributing to thyroid problems. Perhaps oestrogen dominance (e.g. man boobs or period pain) may be partially due to genetic SNPs combined with lifestyle factors like alcohol consumption, both of which decrease the breakdown of estrogen.

  • Evaluation of environmental factors.
  • Are thought processes and unconscious programming contributing?

  • Consideration of the risks and benefits of pharmaceuticals and whether these can be reduced or not.
  • With an understanding of the underlying factors, a wellness plan can be agreed and progress monitored.

Dr Cindy de Villiers

How is it different?

The wellness industry takes one approach and state funded medicine another, so where does Cindy sit? 

  • There’s no such thing as too much data for those wanting to take investigation and intervention to another level
  • The experience of 31 years of registered medical practice in NZ, Australia & South Africa
  • Realistic time and resource allocation to investigate which combinations of treatment modalities to pursue
  • The energy & drive to connect dots and recognize patterns
  • A pragmatic focus on early wins and then building endurance
  • Use of specialty lab testing with current optimal reference ranges
  • Assessment of specific genetic SNPs in relation to relevant laboratory/nutritional and blood testing
  • Prescribing options include compounding pharmacies in New Zealand and Australia
  • Familiarity with conventional and complementary treatments
  • Independent and without a reductionist agenda and only the client’s interests are being served


The fees to see an independent NZ registered doctor

The following maintenance fee schedule applies for current clients (seen by Cindy within the last 2 years):

  • Consultation 60 minutes: $300.00 (if not seen for > 1 year, a minimum 60 min appointment is required)

  • Consultation 30 minutes: $150.00

  • Online Medical Inquiry through Online Portal Secure Message: $30.00 / message or per 10 minutes

  • Repeat Prescriptions: $15.00

  • Nurse Consult/Injection: $15.00 per 15 minutes

The fees partially recover overheads including premise and staff, multiple medical body registrations, insurances, medical systems, equipment, consumables, CPD and continual research.


What is the cost of prescriptions?

Cindy in her specialized role typically prescribes:

  • Non-subsidized medication
  • Medication prescribed for non-endorsed conditions
  • Compounded medications

Any subsidized medications prescribed by Cindy will cost a maximum of $15 per item from a pharmacy rather than a maximum of $5 per item through a state funded service.


What about my GP?

Clients should be enrolled with a GP for acute and emergency medicine, which the taxpayer funds via the state through your GP.

The clinic doesn’t provide acute or emergency medicine.

Treatment for underlying causes cannot begin while clients are in the acute stage e.g. very high blood pressure or intractable distress should be assessed by a GP before looking at advanced treatment options through Cindy.

If initial assessment results are not available from a GP, diagnosis and treatment will take longer and cost more.

Often Cindy works alongside GPs for outcomes.

Other times, a GP and Cindy provide clients with more options, from which the client may choose what is best for them.
