Costello Medical
Summary of work
Costello Medical is a healthcare communications consultancy that fuses scientific rigour, creativity, and social purpose. We are a proudly independent agency, and have grown organically since our foundation in 2008 without sales teams: our growth is driven by strong client retention and referrals and our excellent reputation. Our purpose – being a “force for good” – drives every decision. We are committed to making positive contributions to society and the environment. Our culture encourages open idea-sharing, agile problem-solving, inclusivity and continual learning.
In 2025, we navigated challenging times in the industry by focusing on operational efficiency, whilst bringing greater creativity, innovation and strategic partnership to our clients. We were named Number 1 Independent Creative Agency (PMLive Awards) and Agency of the Year (Headcount >30) (PMi Awards), and received the King’s Award for Enterprise in International Trade. Despite industry headwinds, we grew both our revenue and our team, giving us the financial headroom to expand our force for good initiatives. We recertified as a B Corp, delivered 2,747 pro-bono days (value ~£1.9 million), spent over 480 days volunteering, and pledged 0.5% of revenue to charitable causes. We are proud of everything we achieved in 2025, and look forward to what 2026 will bring.
