Meet the Directors
At the heart of Liberta are its two co-directors, Miriam and Miranda. A partnership that unites lived experience, coaching precision, and international business acumen.
Every engagement begins with both Directors. The scope, team, and terms are agreed together in a single conversation rather than assembled separately, and both remain accountable for the engagement throughout. Day-to-day delivery is held by the case manager and practitioners appointed to each engagement.
MIRIAM CLANWILLIAM
FOUNDER AND DIRECTOR · DIRECTOR OF GROWTH & EXTERNAL RELATIONS
As Director of Growth & External Relations, Miriam leads Liberta’s strategic growth, external relationships and partnerships. She works closely with families, family offices, professional advisers, clinicians and treatment providers, and plays a central role in shaping the scope and commercial structure of each engagement. Often the first point of contact for a family or referring professional, Miriam has a particular ability to understand the wider context quickly, establish where Liberta can add value and shape the right engagement from the outset. Her focus sits across growth, partnerships, commercial strategy and the relationships that surround each client. Having lived and worked in the Middle East for a decade, Miriam has developed a discreet international practice, supporting high-profile individuals and families through nuanced and often complex contexts across the UAE, UK and Europe. She holds a degree in Psychology and Neuroscience and brings experience spanning behavioural health, recovery, movement and wellbeing. Her professional training includes Certified Recovery Coaching, trauma-informed practice and Brainspotting, complemented by lived experience of the recovery process. Together, these give her a broad understanding of the human, clinical and practical dynamics that sit behind complex situations. Miriam works closely with leading clinicians and treatment providers internationally, combining cultural awareness, commercial instinct and a strong ability to build trusted relationships across complex personal and professional contexts.
MIRANDA MARSH
FOUNDER AND DIRECTOR · DIRECTOR OF CARE MODEL & QUALITY
As Director of Care Model & Quality, Miranda leads Liberta’s care design, case architecture, quality and client experience. She is responsible for translating each referral into a coherent, clinically informed structure of support, and for ensuring that what is designed at the outset is delivered consistently in practice. Once the initial scope of an engagement has been established, Miranda takes the case forward. She assesses the level of support required, builds the appropriate multidisciplinary team and holds the framework around the individual and family from mobilisation through review, transition and exit. Her focus is on making sure each programme remains responsive, proportionate and aligned with the client’s evolving needs. With more than a decade of experience across case management, recovery coaching and leadership, Miranda has worked across the UK, US and Middle East with HNW individuals, families and family offices, including public figures from the music and film industries. Her work has involved close collaboration with psychiatric teams and, where appropriate, alongside public mental health services, giving her a strong understanding of how private and statutory systems can intersect around complex care. Miranda’s professional foundation is in art psychotherapy and trauma-informed practice. She is a Certified Trauma Coach and Certified Recovery Coach, and is qualified in DBT Skills methodology, with additional specialist training in eating disorders, nutrition and obesity. Her wider training includes family systems, high-conflict de-escalation, enhanced safeguarding and international child-protection practice. She has managed cases involving many of these presentations directly, bringing practical experience alongside formal training to the design and oversight of care. Her lived experience adds a further layer of understanding to the way she works with clients and the wider systems around them. Miranda is particularly skilled at translating complexity into a clear and workable structure, identifying priorities, coordinating the right multidisciplinary input and continually reviewing how an engagement is functioning in practice. She combines discretion, clinical awareness and humanity with a strong instinct for quality, continuity and client care.

She works closely with the Directors across operational development, programme delivery, data protection and the infrastructure required to support increasingly complex private client engagements. She brings more than fifteen years of experience across behavioural health, recovery, research, clinical operations and governance. Her career has included frontline work in the United States, national research and service-development programmes, the establishment and management of a London outpatient recovery clinic, and senior systems and data protection roles within European healthcare.

Alongside Liberta, Rebecca continues to hold executive and governance roles across healthcare, technology and recovery. This wider perspective brings valuable insight into how sophisticated care organisations can grow without losing the quality, discretion or accountability on which their work depends.

A letter from the founders
"For more than a decade, we have both worked at the intersection of recovery, mental health and high-performance wellbeing, guiding individuals, families, and family offices through some of their most complex challenges. We founded Liberta to offer a truly integrated model of care, bringing world-class specialists together within a single, trusted framework."
