Maggie Trevillion — MRCPod BSc (Hons) MSC, Founder

Born To Care

Born and raised in London, Maggie has dedicated more than 20 years to advancing foot and lower limb health, helping thousands of people improve their mobility, comfort and quality of life through exceptional podiatry care. Her career has spanned the NHS, Ministry of Defence and private healthcare, but throughout every role she was driven by the same belief: healthy feet have the power to transform how people move, feel and live.

From early in her career, Maggie was also passionate about serving local communities and creating meaningful opportunities for the people she employs. She recognised that exceptional healthcare is about far more than clinical expertise alone; it is about building environments where people feel genuinely cared for, listened to and supported.

Movement Changes Lives

Maggie believes exceptional podiatry is about far more than treating feet alone.

It is about helping people stay active, maintain independence and continue enjoying the moments that matter most.

Whether that means returning to sport, keeping up with grandchildren, enjoying holidays without discomfort or simply walking comfortably each day, movement plays a vital role in our wellbeing and quality of life.

This belief sits at the heart of Callen Olive's philosophy:

Healthy Feet. Healthy Body. Healthy Mind.

Building Callen Olive

In June 2012, Maggie founded Callen Olive, formerly Walk This Way Podiatry, with a vision to create something different from a traditional podiatry clinic.

She wanted to create a place where clinical excellence, wellbeing and genuine human connection could exist seamlessly together. A place where people feel listened to, supported and cared for while receiving exceptional treatment tailored to their individual needs.

Today, that vision continues to shape everything the practice does.

Under Maggie's leadership, Callen Olive has grown into a multi-award-winning centre for lower limb health and wellbeing, supporting thousands of patients across Buckinghamshire and Hertfordshire. The practice has become recognised for combining exceptional clinical care with an outstanding patient experience, embracing innovation, evidence-based treatments and a preventative approach to foot health while remaining rooted in compassion, kindness and genuine care.

Known for her determination, warmth and forward-thinking approach, Maggie leads with integrity, empathy and high expectations. She believes excellence is not a destination but a standard to aspire to every day, and this pursuit of exceptional standards has become a hallmark of the Callen Olive experience.

She is equally passionate about developing people and creating meaningful careers. Through a culture built on kindness, collaboration and continuous learning, she strives to create an environment where both patients and team members feel valued, respected and empowered to thrive.

Recognised for combining clinical expertise with warmth and compassion, Maggie has dedicated her career to redefining foot and lower limb care and demonstrating its vital role in helping people live healthier, more active and more fulfilling lives.

Her vision has always extended beyond podiatry alone: to elevate how people think about foot and lower limb health and establish wellbeing as an essential part of everyday life.

Beyond The Clinic

Alongside Callen Olive, Maggie is also the founder of a successful multi-award-winning leg and foot wellbeing collection inspired by her podiatric expertise and passion for self-care. Created to bridge the gap between healthcare and self-care, the collection reflects her belief that foot and lower limb wellbeing deserve the same attention, ritual and care we naturally give to the rest of our body.

Through this work, she has helped elevate the profile of leg and foot health, making it more accessible, desirable and an integral part of everyday wellbeing.

Life Outside Callen Olive

Maggie lives in Chesham with her husband and children. Outside the clinic, she enjoys long walks in the Chiltern Hills with her beloved whippets, practising yoga, spending time with family and friends and making the most of life's simple pleasures. She appreciates great food, loves being outdoors and values the balance that comes from creating meaningful moments with the people she loves most.

Rooted In Care

Everything Maggie has built at Callen Olive is guided by one simple philosophy:

We care about people.

We care about comfort.

We care about confidence.

We care about wellbeing.

We care about movement.

And we care about helping people live life with greater ease and enjoyment.

Because when people feel genuinely cared for, they move differently, live differently and experience life more fully.

"I believe comfort, confidence and wellbeing begin from the ground up, and that caring for people's feet is ultimately about helping them live life to its fullest."
