Functional Nutrition Coaching + Labs

for High-Performing Executive Women

Your Number One Income Producing Asset Is You
It's Why Your Health Must Come First

I help high-achieving, mid-life women become burnout-proof by focusing on the Gut-Brain connection so they can reach new levels of peace, purpose and performance.

More Energy

If you’re sleeping for 7+ hours a night and still can’t spring out of bed before your alarm ready to take on the day. Or you’re struggling to get to sleep or stay asleep, your body is telling you something! We’ll identify the underlying energy drain, and fix it so you can wake up refreshed every day, ready to take charge.

More Peace

Are you worrying about how you’re going to have the energy to attend all the commitments in your life? Together, we can uncover the physiological and psychological causes to restore harmony throughout your body & your life, so that you can actually enjoy your success and all that comes with it!

More Freedom

If your body is standing in your way, so that you’re missing meetings or unable to show up for social engagements, you don’t have the freedom to pursue your passions. Together, we can take control of your health so you can experience the increased abundance, connection and freedom you deserve.

You Get a Step-By-Step System Designed Exclusively For High-Performing Women, With Data-Driven Protocols and Mindset Mastery to Reset Your Body and Mind

Functional Labs

I help you with non-diagnostic labs to see where your body is under stress to make sure that you don’t develop a disease. What I do is correlate lab results that look across the body’s systems to identify H.I.D.D.E.N. stressors – Hormones, Immune System, Digestion, Detoxification, Energy Production and Nervous System – that are contributing to your lack of energy or feeling stuck. 


Once we’ve established where the weak links are, we create a plan to address imbalances through D.R.E.S.S. (Diet, Rest, Exercise, Stress Reduction and Supplements) for a minimum of 90 days.  My favorite success story is the client who had been on a vegan / vegetarian diet for years unable to lose weight and struggling with her energy. Within 1 week of cleaning up her nutrition, she shed 7lbs.


After we’ve consciously created the plan to reset your biochemistry, we’ll reprogram any limiting beliefs through the transformational cognitive behavioral hypnosis. Elite athletes always visualize their victories, and are more likely to achieve success once they do. I’ll help you re-program your mind guided breathwork, elevated emotions, visualization, and repetitive affirmations while in a deeply relaxed state.

Incredible Transformations through Gut Health

Stacy, California | Stacy came off her anti-depressants

Sharon, London | Sharon had a complete change in her wellbeing

What My Clients Are Saying…

“One of the best decisions I’ve ever made.”

I was feeling more and more unwell, with no hope of a diagnosis, so I decided to take a chance and sign up. I am so glad I did. Within a few weeks, I started to feel so much better. I can’t say enough how grateful I am to Despina and Raewyn, as without them, I really worry about what would have happened to me.

-Alison, Essex

“Once I ran the functional labs, I completely cleared my skin.”

I was experiencing some symptoms around my hormones, my gut, my mood, and my skin that I couldn’t figure out with conventional medicine, despite running numerous tests. However, once I ran the functional labs, I completely cleared my skin by following a tailored diet and a course of supplements, which I find absolutely remarkable.

Alice, London

Hi, I’m Raewyn Guerrero


Like you, I know what it’s like to feel burnt out, uncomfortable, and frustrated with the endless merry-go-round that is mainstream healthcare.

My story is a long & crazy one. After years of searching for answers to my own health problems (anxiety, IBS, eczema, the list goes on…) with conventional medicine, I felt hopeless. I was tired of being told there was nothing wrong with me, trying alternative methods – tired of being tired.

Finally, everything changed when I discovered functional medicine. Looking at wellness from this personalized, data-driven perspective made sense to me and completely transformed my health & and my entire life!

Today, I help women live healthier lives by taking an investigative approach that leverages cutting-edge science & diagnostic testing.

As a Functional Health Practitioner, Cognitive-Behavioural Hypnotherapist and Corporate Wellness Consultant, functional diagnostics are the starting point to understand why you feel anxious, burnt out, stuck or stressed.
