I am Dyann Heward-Mills and I have spent the last three decades honing my skills as a mother, a lawyer and a business leader.
In recent years, I have also qualified as a psychotherapeutic counsellor. As I look to the next chapter of my career, I aim to combine these experiences to provide services in four key areas, all with the common thread of driving growth, for businesses and individuals.
Four key areas
Each strand of my work draws on a different chapter of my life, and each focused on trust building and effective communication.

01 · Business Leadership
I am founder and CEO of global data protection office HewardMills, which provides regulatory advice and specialist Data Protection Officer (DPO) services to multinational organisations. We help companies comply with data laws and regulations, including cybersecurity standards and the requirements arising from emerging technologies.
At the forefront of data regulation and ethics, we are a multi-disciplinary team of data protection practitioners, lawyers, corporate governance and cybersecurity experts. Trusted across industries including life sciences, technology, retail and banking, our focus is on delivering data dignity with integrity in over 70 jurisdictions.
HewardMills is proudly B Corp certified and champions diversity, working with likeminded organisations to be a global force for good.
If your organisation operates in multiple jurisdictions and you would like to know whether your data protection programme is fit for purpose, get in touch at dpo@hewardmills.com or call +44 (0) 20 3367 1245.


02 · Coaching
I run group retreats harnessing the beauty and power of nature to enhance communication and promote growth. Escaping the urban jungle can change perspective and reinvigorate.
Group sizes range from five to 20 individuals. Together we explore the many aspects of groups: their formation, communication dynamics and intercultural nuances, and the ways in which we build resilience and emotional maturity.


03 · Counselling
I am a qualified psychotherapeutic counsellor with a foundation in humanistic psychotherapy. My philosophy is that, as individuals, we all have the capacity for growth and evolution given the right conditions, and my aim is to facilitate that through the therapeutic relationship.
Regardless of who we are in life, we all face challenges. Having a trusted person to help us find meaning in them can make a significant difference to the way we navigate them. There is always an opportunity for support, understanding and holding.
My style is to incorporate creativity into the therapeutic experience. To this end, I have recently completed an introduction to child and adolescent psychotherapy course at the University of Cambridge. I support private clients in partnership with Headstrong Counselling.


04 · Philanthropy
I sit on the board of a number of organisations that champion equality, open opportunity and help people and communities thrive. These include:
Dee’s Retreat
A reflective Solstice gathering to recognise the light within HM and explore the energy we want to attract. Interactive and creative throughout, so please confirm your attendance and I can plan the day around everyone.
As individuals, we all have the capacity for growth and evolution, given the right conditions.
Let’s talk
Whether you would like to discuss your data protection, cyber security and AI governance needs, join a retreat, explore counselling, or learn about my philanthropic work, I would be glad to hear from you.
