About Us

We are Koren and Mark from Bristol CBD — a small, passionate team on a mission to make high-quality CBD and medicinal mushrooms accessible to everyone.

Our journey began with a personal search for natural ways to manage stress, pain and burnout. After discovering the power of whole plant CBD, we knew we had to share it.

Since 2017, we’ve been helping people across the UK find trusted, effective alternatives to pharmaceutical meds — all backed by third-party lab testing, ethical sourcing, and genuine human support

💚 What We Believe

We believe that plants can do powerful things — when grown right, handled with care, and shared responsibly.

Bristol CBD shares its profits by supporting charities in the UK and beyond:

1. Treesisters

For many years we have been proud to support Treesisters in their mission to fund ethical, community-led tree planting projects that take direct climate action, empower women and champion local and indigenous communities. By supporting TreeSisters, we contribute to a sustainable future, while also promoting the empowerment of women as key leaders in the fight against environmental degradation.

Every time you order from us you are contributing towards planting more trees and helping to foster biodiversity and fund ecological education.

2. Bristol Refugee Festival

We support refugees through donating to Bristol Refugee Festival which is the South West’s only festival for, with and by refugees. The festival brings communities together to connect, share and celebrate and gives refugees and asylum seekers an opportunity to meet people, perform, trade, gain vital employment skills and become active members of their communities.

Supporting this festival aligns with our commitment to inclusivity, diversity, and the empowerment of marginalised communities.

3. Sustrans

We support Sustrans because it is dedicated to creating healthier, more sustainable communities by promoting walking, cycling, and the development of safe, accessible infrastructure. Their work in transforming public spaces, reducing carbon emissions, and encouraging active travel helps improve physical and mental well-being, while also addressing critical environmental issues like climate change and air pollution.

By supporting Sustrans, we contribute to building a future where sustainable transportation options are available to all, fostering healthier lifestyles and greener, more livable cities.

4. AfriPads

We support AfriPads in Kampala, Uganda because of their crucial role in improving menstrual health and hygiene for women and girls across Africa. By producing affordable, reusable sanitary pads, AfriPads helps break the cycle of period poverty, enabling girls to stay in school and women to pursue their daily activities without interruption. Their mission not only promotes gender equality but also offers an environmentally sustainable solution by reducing waste from disposable products.

Through empowering communities and addressing this critical need, AfriPads contributes to improved education, health, and economic opportunities for women and girls.

Meet The Bristol CBD Team

Mark Dunn

Mark is the heart behind Bristol CBD — a wellness advocate, community-builder, and passionate believer in the healing power of plants.

After spending over a decade in the fast-paced corporate world, Mark experienced burnout first-hand. That moment became a turning point, leading him on a journey of self-discovery, meditation, and natural health. It was through this process that he discovered CBD — and the profound impact it could have on mental clarity, pain relief, and emotional balance.

In 2018, alongside his partner Koren, Mark co-founded Bristol CBD with a simple mission: to make high-quality, affordable CBD accessible to everyone — especially those who, like him, were looking for a gentler, more sustainable way to feel better.

Mark now leads the team with warmth, humour and a strong ethical compass — always putting people before profit. Whether he’s helping a new customer understand the difference between Gold and Whole Plant oil, or guiding someone through their first steps on their wellness journey, Mark brings honesty, care and deep knowledge to everything he does.

When he’s not blending oils or answering customer questions, you’ll find Mark meditating, walking in nature, or enjoying time with his family and community in Bristol.

“More and more people bless us with their trust and we feel a deep responsibility to ensure that we earn that trust."

Koren Barnwell

Koren is the nurturing force behind Bristol CBD — an intuitive listener, wellness educator, and fierce advocate for natural, accessible healing.

Her journey into the world of CBD began through personal experience, as she explored holistic ways to manage stress, hormonal shifts, and chronic health challenges. Frustrated by confusing information and overpriced products, she partnered with Mark to create something different: a transparent, people-first CBD company grounded in care and integrity.

Koren brings a calm, grounded energy to everything she does — whether that’s developing new blends, offering guidance to customers, or ensuring every product that leaves their hands is something she’d give to her own family.

She’s especially passionate about supporting women through life’s transitions — including perimenopause, anxiety, and burnout — and is always happy to share her lived experience with those seeking support.

Koren believes healing starts with trust — in your body, your choices, and the people who guide you. That belief sits at the heart of Bristol CBD.

Koren has over 25 years of experience working in various naturopathic medicine modalities. With a background in Acupuncture and Oriental medicine and more than a decade working specifically with bowel health problems alongside health coaching, Koren has a wealth of knowledge to share.

“I have worked with a multitude of health issues over the decades, supporting clients through all kinds of emotional, physical and spiritual crises. I feel there is much to be said about a simple approach to wellness and I believe that by reducing stress alone, healing can occur more readily. That’s why I was initially so drawn to CBD products.

I am wholeheartedly committed to the health and well-being of our clients, but I mostly believe in empowering people to help themselves. The abundance of positive feedback that we have received about our CBD products over the years is truly heart-warming and humbling and continually motivates me to keep sharing the CBD love."

When she’s not working, you’ll find her connecting with nature, crafting herbal remedies, or holding space for her community with quiet strength and care.
