About Us


Derval Dunford and Mick Hogan


Derval’s interest in mindfulness and yoga nidra was inspired by her life challenges. She suffered from PTSD (Post Traumatic Stress Disorder) in early adulthood, chronic fatigue and MCS (multiple Chemical Sensitivity) in her thirties. 

Being someone who has a busy mind, is creative, likes to be productive and dislikes wasting time, Derval, not naturally a ‘zen’ type, has come to realise, that the only way she can be her ‘busy’ self, and yet flourish, is to balance the busyness with a smattering of stillness and calm, balancing the 'doing' with a little 'non-doing'. 

 With her gentle and fun style Derval is only interested in 'stuff that works' . Content and practices are accessible and practical. Based on simplicity, and a common sense approach she makes mindfulness breathwork and yogic sleep (traditionally know as Yoga Nidra) effortless. Derval has been teaching since 2006.

Derval is a qualified MBSR (Mindfulness Based Stress Reduction) and Yoga Nidra teacher, HeartMath Coach, BreathMastery teacher, Stress Management Coach and Breath-Body-Mind teacher. She has also studied Hypnotherapy, Aromatherapy, Counselling Skills. She is co-founder of ‘Mindfulness Matters’, and has trained thousands of Irish primary school teachers and children in mindfulness, relaxation, and well-being.

Derval has been facilitating Mindfulness and Relaxation workshops and courses for many years, has worked with a variety of organisations including regular workshops and courses with the HSE, INTO, and Mayo Education Centre, she speaks regularly at related conferences.

 Yoga Nidra can be recharging, relaxing or sleep inducing. Everything that is not needed is washed away. It is a really productive way to use twenty minutes during your day, because you are full of energy, enthusiasm, and more focused after the practice. It is also a prefect way to drift into restful sleep. Practising Yoga Nidra is A Slice of Time invested very wisely.


Our mindfulness practices  can be woven into daily life, they help ground you so you can interact with your inner and outer world with more wisdom and ease. We show up for our lives, learn to be ourselves, and as a result live life to the full.

 Derval's breathwork practtices are so simple and yet so powerful. Breath is an inbuilt self-regulation tool than anyone can learn to use. Suí breath praces are based mainly on coherent breathing, a scientifically measurable state characterized by increased order and harmony in mind, emotions and body.


It is Derval’s belief that ‘simplicity is the key’. Her presentations, workshops and courses are down to earth, and she likes to bring a sense of enthusiasm and craic to her work. Above all she emphasises that mindfulness, Yoga Nidra and HeartMath don’t have to be taken too seriously. You don’t need to strive, to do your best, to be perfect, to be enlightened! You just need to sit or lie down, explore, and repeat. Everyone’s experience is different, which is the way it should be, no two people will ever be the same....no two practices will be ever the same.


Derval’s work has been endorsed by medical and health-care professionals both nationally and internationally. Her previous CD called ‘Sui’ continues to send people to sleep (intentionally!) and guide them through grounding mindfulness practices. Her co-produced kid’s CDs are a huge hit at home and in schools. Check out www.mindfulnessmatters.ie for more details.


Mick’s irrepressible enthusiasm for the wonder of nature is infectious. He is passionate about connecting, or re-connecting people with nature, drawing them out of the virtual world and into the here and now. 

While he specializes in bird survey work, he also presents a variety of  workshops, walks and talks for schools, and other groups both onsite and on zoom.  Mick is a GMIT qualified Marine and Countryside Guide, and Climate Control Ambassador in Mayo. Mick’s past work in this area includes guided walks and camping trips with teenagers, teaching simple survival skills. His present work in this area includes nature workshops, walks and talks with adults and children.

Where does Suí come from?

The Celts had an outdoor spirituality. The essence of Celtic spirituality was presence. Natural rhythm was honoured. There was a deep connection with the earth.

The word Suí is the Irish word for ‘sit’. The title was inspired by the ‘down to earth’, yet creative nature of the Irish language, the simplicity of Derval’s practices, the importance of good posture, and the need to balance all the running around with sitting for a few minutes here and there.

Suí Mindfulness & Yoga Nidra is a very small business based (just Derval and Mick) in the beautiful town of Westport, Co. Mayo, part of the Wild Atlantic Way, on the west coast of Ireland.

Inspiration for their work comes directly from the local area, mossy woodlands, expansive sandy beaches, rolling waves, rugged cliffs, rock formations and green fields. With Westport town sitting in the shadow of Croagh Patrick, Ireland's famous holy mountain, The essence of Suí is connection with nature, freedom, and a strong sense of being grounded.


Derval facilitates programmes for schools, businesses, and groups, she also creates and narrates the Suí Mindfulness & Yoga Nidra tracks, Mick facilitates school's nature workshops, walks and talks on site and on zoom. Stephen McHale, Derval’s son, composes and performs the sublime background music for the tracks and videos.

Suí CDs are created, designed, and recorded in Ireland.

‘Time and time again we miss out on the great treasures in our lives because we are so restless. In our minds we are always elsewhere. We are seldom in the place where we stand and the time that is now.’
