Lived experience and healing
My approach is also shaped by my own healing. For years, body dysmorphia and perfectionism were the visible expressions of deeper trauma and the pressure to perform strength.
Through therapy, functional nutrition, breathwork and carefully held psychedelic integration, I began to understand how the past can live in the body and why lasting change needs more than discipline.
That experience gave me greater perspective, humility and clarity about the kind of support I want to offer.
How I work
Alongside nutrition and functional medicine, I have completed more than four hundred hours of breathwork facilitator training, with a trauma-aware and somatic approach.
I also have postgraduate training in trauma, psychedelics and integrative mental health. This has deepened my understanding of how past experiences, protective patterns, the nervous system and a person’s wider sense of self can shape their health. It informs how I understand the person in front of me, rather than looking only at symptoms or behaviour.
Today, I work internationally with private clients and organisations. Whether I am working one-to-one, writing or speaking, the aim is the same: to make health feel more intelligent, inclusive and human, without turning it into another standard of perfection.

Author of Letting Go of Perfect and The Queer Guide to Nutrition and Lifestyle
I work with a small number of private clients and with organisations that seek more thoughtful conversations about health, identity and change.
Working where physical health, identity and healing meet.
I’m an award-winning nutritionist, a Functional Medicine Certified Practitioner, an author and a speaker with more than fifteen years of clinical experience.
I work across nutrition, queer health, body image and healing, bringing evidence-informed practice together with an understanding of identity, culture and lived experience.
How I got here
Before training in nutrition and functional medicine, I worked in drug and alcohol counselling. It taught me early on that behaviour rarely makes sense when separated from what a person has lived through.
That understanding has stayed with me throughout my clinical work. It continues to shape how I think about symptoms, coping and what allows meaningful change to happen.
Queer health
Queer health has been central to my work. Mainstream wellbeing advice often overlooks how shame, safety, community, access to care and the pressure to belong can affect our health.
I wanted to help create something more honest: health information that reflects the lives queer people actually live.
This work led to Naked Nutrition, now expanded and updated as The Queer Guide to Nutrition and Lifestyle, and Letting Go of Perfect: A Gay Man’s Guide to Healing from Body Dysmorphia.
