About Themis Wealth Management

Who are Themis?

Themis Wealth Management is the trading name of Gannon Wealth Management Ltd, proudly becoming directly authorised by the Financial Conduct Authority in 2020.

Founded by Kate Gannon, Themis was created after more than three decades in the profession, when Kate recognised it was time to take the final step: to build a firm fully aligned with her values, her standards and the level of service she believed clients truly deserved.

By establishing her own business, she created the freedom to shape every aspect of the client proposition — a thoughtful, independent and highly personal approach to financial planning centred on life, family and legacy.

Kate’s knowledge, professionalism and contribution to the profession have been recognised throughout her career. In 2016, she received one of the profession’s highest individual honours: Chartered Financial Planner of the Year from the Personal Finance Society.

Her standing within the profession has continued to grow. In 2025, Kate joined the Board of the Personal Finance Society, before being appointed Vice President in September 2025 — a reflection of the trust placed in her leadership, judgement and commitment to the future of the profession.

That same level of trust has also been recognised publicly. In December 2025, Kate appeared on The Martin Lewis Money Show, further reinforcing the confidence placed in her expertise both within the profession and by the wider public.

Earlier accolades include Achiever of the Year 2015 and Female Financial Planner of the Year in 2006, reflecting a long-standing commitment to excellence, leadership and trusted advice.

Today, Themis continues to bring that same standard of wise counsel, independence and care to every family it serves.

Alongside Kate Gannon, Themis is supported by Lucy Opie, whose calm oversight and exceptional organisation help ensure every detail is carefully managed.

Behind Lucy sits a wider team of experienced and supportive administrators and paraplanners, working seamlessly in the background to make every aspect of your journey feel smooth, responsive and well cared for.

Together, this creates an experience that is personal, reassuring and highly considered — giving you confidence that every detail of your financial life is being looked after with care and professionalism.

At Themis, we believe the best financial planning starts with listening. By taking the time to truly understand your life, your priorities and the stages still ahead, we build a plan that moves with you as life evolves.

Our role is to take the pressure away, so you can focus on living life to the full. Behind the scenes, we carefully build, monitor and adapt your financial plan to help future-proof both your needs and those of your family.

Wherever possible, our focus is on helping you continue doing what matters most — enjoying the life you want to lead, with confidence in the decisions that support it.

Every client relationship is built around thoughtful, flexible and highly professional planning, designed to help you achieve your life goals with clarity and peace of mind.

Why “Themis”?

Named after Themis (pronounced Themm-is), the Greek Titaness of wisdom, justice and good counsel, our name reflects the values that shape every client relationship.

In Greek mythology, Themis represented wise judgement, order and the ability to see the bigger picture. Those same principles sit at the heart of how we guide families through important financial decisions.

For us, true financial planning starts with understanding the life behind the wealth. It begins with listening, thoughtful conversation and taking the time to understand your ambitions, your concerns, your family and the future you want to create.

Investment portfolios, pensions and cashflow planning are, of course, important. But they are tools, not the purpose.

The real purpose is stewardship: helping you make wise decisions, protect what matters most, and use your wealth to create a life of freedom, security and meaning — on your terms.

Themis stands for calm guidance, wise counsel and a considered approach to wealth that places your life, your family and your legacy at the centre of every decision.

Monty and Max Gannon, CBO and JBO (Chief and Junior Barking Officers)

Monty and Max Chief Barking OfficersWhere they Live
We live at home in Newquay with our family, not sure where but it has a great garden and lots of great walks and beaches we can run around on.

Their Family and Interests
We were adopted by our parents and are quite spoilt, so they say. Monty is the Big Brother and Max is quite new to the Themis family but is finding his paws.

We love to go on long walks and swim in the sea and especially like to get as muddy as possible which we are not sure anyone else is that keen on but that’s their look out. We also collect cuddly toys and have a huge basket of them at home which we sort through most evenings much to my Mum’s moans as they all have to come out and be checked!

Their Role in the Company
We are Chief  and Junior Barking Officer and also like to ensure that anything left in a bin in the office is shredded before it is taken away and disposed of correctly.

Kate Gannon Themis Wealth Management

Kathryn (Kate) Gannon

Founder, Director and Chartered Financial Planner

Where they Live

I live in a small hamlet on the outskirts of St Newlyn East, a beautiful Cornish parish around five miles south of Newquay.

Cornwall’s landscape and coastline are a constant source of perspective and inspiration, and the Isles of Scilly in particular hold a very special place in my heart.

I am equally passionate about my work in London as well as Cornwall, and value the perspective that comes from supporting clients across both locations.

Family and Interests

I am married and have two grown-up children.

Outside work, my happiest moments are often the simplest: long walks with my three golden retrievers and Italian greyhound, time spent with my husband, and escaping to the Isles of Scilly whenever possible.

I have a deep love of the countryside, reading, and spending time with my wonderfully lively friends and family, who keep me grounded and smiling through the busiest seasons of work.

I am also deeply passionate about rehoming animals, something that feels especially close to my heart as a lifelong dog lover and support many charities in this area, and one of our Goldies came from one of these charities too.

The balance of Cornwall, London, family life and the dogs gives me perspective and reminds me why financial planning is ultimately about creating freedom and meaning.

Her Role in the Company

As Founder, Director and Chartered Fellow Financial Planner, I lead the vision and client philosophy behind Themis Wealth Management.

My role combines strategic leadership with the privilege of working closely with clients and families to help shape the life their wealth is designed to support. I am taking further qualifications in this area to become a Chartered Director with the Institute of Directors and invest heavily in the education of myself and my team.

I am deeply passionate about the continued growth of the financial planning profession and proud to support this through my leadership roles as a Board Member and Vice President of the Personal Finance Society.

I am also honoured to be a member of Million Dollar RoundTable (MDRT), reflecting my commitment to excellence, professionalism and the highest standards of client care and raising more money for other charities around the world.

I also appear from time to time on television alongside Martin Lewis on The Martin Lewis Money Show, helping bring trusted financial guidance to a wider audience.

Alongside leadership, I remain closely connected to the day-to-day realities of running a growing business — and yes, I still occasionally make sure the loo rolls are stocked, because leadership is always about doing what needs to be done.

Testimonials

What Our Clients Say…

Kate brings a wealth of detailed knowledge and caring personality to an important subject for clients.

Kate however approaches the subject in a really personal way and finds out about the client, their life, their plans and their financial needs. This leads what she does rather than just looking at the products.

Definitely recommend speaking with her to see for yourself.

My wife and I have been ably guided by Kate Gannon of Themis around the intricacies of domestic financial planning from the company’s outset.

Kate has provided excellent value for money for our investments. We get home visits with a friendly approach and Kate is always available by phone or email for any queries. We have had Five Star service and would thoroughly recommend Themis to prospective clients.
