About
An inspiring emotional wellbeing coach for children in Yorkshire and beyond
Wish you could empower the young people in your life to uncover their innate strength and mental wellbeing? To shape success on their own terms? I can help.

My Story
Hi! I’m Mariella – a mum of two and a mental wellbeing coach and facilitator. Born and raised in Bulgaria, I worked hard to succeed according to society’s expectations. After gaining a masters in International Business Relations, my government position saw me travelling the world negotiating international travel corridors. After I met my now husband, I moved to the UK. More studying and more jobs in financial services, IT project management and business change management followed. But I wasn’t fulfilled by what I was doing.
I decided to step off the corporate career ladder to be more present for my family and re-evaluate my goals. Through volunteering as a Rainbow Leader for the Girl Guides and being a ‘Big Sister’ for Girls Out Loud, I realised how much I loved working with children.
While retraining as a coach, I came across the ‘inside-out’ approach to understanding the mind and emotions. I applied this insight when running mental health workshops in primary schools. These windows of time in which children could talk about their thoughts and feelings were so empowering. I founded Mind Garden York to offer this sort of support in schools and after-school settings.
Why I love being an emotional wellbeing coach for children
Through my workshops and sessions, I get to share what I wish I’d known about mindsets and emotions as child and a teenager. My goal is to give children the tools they need to make the right life choices for who they really are.
Mind Garden York was set up after the first 2020 lockdown, and I run it alongside my private practice. It’s a Community Interest Company (CIC) meaning it exists to benefit the community. Being a CIC means more types of funding is available.


Why Mind Garden?
Just like a garden, a young person’s emotional wellbeing needs to be nurtured.
I also love to garden! For me the garden is a place to savour a mindful moment, its a place to marvel at the miracles of nature and witness the intelligence of live in action. The benefits of being in nature to our wellbeing are scientifically proven and well documented.
I have a vision for a beautiful communal green space, a real-life Mind Garden, where I can engage children in sowing and growing as part of our wellbeing workshops. I know this will materialise one way or another in the future.
