Katie Collin

Katie specialises in advising GP partners, Primary Care Networks and healthcare leaders on the financial and structural challenges facing modern primary care. With over 10 years’ experience in medical accountancy, she works at the intersection of tax, pensions, governance and strategy, helping clients navigate change with clarity and conviction.

She began her career in audit at HW Fisher before moving to BDO, where she further developed her experience within professional services. She later chose to focus exclusively on the healthcare sector, joining Ramsay Brown to build deep expertise in medical accountancy and to work closely with GP partners and primary care organisations. That decision defined the direction of her career.

Compliance is only the starting point. She advises on partnership evolution, funding reform, performance benchmarking and long-term sustainability. In an environment of increasing financial pressure and regulatory complexity, what excites her most is working closely with clients to understand what they truly need, helping GP partners and practice leaders tackle complex financial and structural challenges with clarity and confidence.

Alongside her client advisory work, she is actively engaged in shaping the wider conversation around the future of primary care. She regularly contributes to sector publications and industry commentary, and she hosts the “Beyond the Balance Sheet” podcast, where she explores the financial and operational issues impacting clinicians and practice leaders. she is passionate about championing a sustainable and forward-looking model for general practice, ensuring financial insight plays a central role in its evolution.

Laurence Slavin

For nearly four decades Laurence has been at the centre of financial and structural change in the NHS, advising generations of GPs, consultants, and healthcare professionals through some of the most consequential shifts in the history of British medicine.

He trained as a Chartered Accountant with Stoy Hayward (now BDO), specialising in tax, before joining Ramsay Brown in the mid-1980s. The firm was his father’s. When he passed, Laurence took on the responsibility of leading it and made it his mission to build the firm the medical profession deserved: one defined by genuine specialism, earned trust, and advice that made a real difference to people’s careers and livelihoods. Appointed Partner in 1987, he led the firm’s development ever since.

His expertise spans NHS contract reform, pension planning, partnership structuring and disputes, and long-term strategic advisory for medical professionals at every stage of their careers. He has advised the NHS Executive, contributed evidence to the Doctors and Dentists Review Body, and sat on national committees for the Department of Health and the British Medical Association. He is a published author and a regular contributor to the healthcare finance press, and has delivered talks across the UK and internationally.

Clients come to him for technical expertise. What they remember is something different: that he listens carefully and that he understands the pressures they are under. Good advice is built on that kind of attention. It always has been.

As a mentor, he has spent years helping to develop the next generation of advisers within the firm, instilling a culture of curiosity, integrity, and professional pride. That is as important to him as any technical work he has done.

I joined Monahans as part of the transition from Moore South West, where I had been for 15 years, often working with clients in the healthcare sector, such as medical and dental practices. I had previously worked for a number of professional firms in audit and accountancy roles, supporting a wide range of clients including listed companies, schools, housing associations and charities. When I’m not advising clients, I am very keen on creative arts, baking and cooking for family and friends, and travelling in the UK and abroad.
