Talent management for exceptional artists.
Founded by Gary O’Sullivan in 2021, he’s joined by Sarah Hanna, Hermione Halpin, Ella Weston and Veronica Sesti.
Born and raised in Dublin, Gary started working weekends and school holidays for John and Ros Hubbard in their Dublin office. He went on to study Musical Theatre at The Guildford School of Acting and after 5 years of working professionally, he returned to John and Ros, this time in their London office, where he found his true passion for the film and tv business. He moved to Troika, one of the UK’s most successful agencies, where he progressed within the company, to become a partner and grow an impressive list of actors over 15 years, a list he continues to build upon since founding Accelerate in 2021.
Hermione graduated with a first-class degree from the Arts University Bournemouth and soon after graduating found her way to the other side of the industry, beginning her career in casting nine years ago. Her experience working with some of the most prominent casting directors and agents has led her to Accelerate where she is now growing a list of exciting talent alongside working with Gary.
Having grown up in Ireland, Sarah came to London to study art history at The Courtauld Institute. She began work as a casting assistant shortly after completing her degree where she first worked with Gary at Hubbard Casting. She has been working in casting, production and talent management ever since and came full circle to join Gary again as he began Accelerate. Sarah works closely with Gary, co-agenting on some clients.
After studying French and Italian at Durham University and Musical Theatre at The Royal Conservatoire of Scotland, Ella worked in production and casting in Glasgow before joining Accelerate as an assistant to Gary.
After studying International Relations at PUC-São Paulo and Sciences Po Paris, Veronica worked in various roles within the art department and production for film and TV in Brazil and the UK, before joining Gary’s office at Accelerate.
