Rhiannon Owen

Principal Writer

Since joining GCC as a Medical Writer in 2004, I have been given many opportunities to grow and learn as a writer. I’ve travelled all over the world, supporting clients with symposia, advisory boards and educational meetings, before focusing more on publication planning and delivery over the last couple of years.

I now enjoy passing on that knowledge and experience to our newer writers to help them develop their skills within our supportive team environment. A good work–life balance is strongly encouraged here, which gives me time to take up a ridiculous number of hobbies outside the office, including musical theatre, fibre crafts and, most recently, working towards running a 5k (very slowly).
