New Managing Director

November 2025

We’re pleased to announce an important new chapter in our development at OCMA.

After a period of continued growth and success Clare White has been appointed as our new Managing Director. Clare succeeds Sean Mahon, who has led the practice with dedication and vision over the past 17 years, strengthening its reputation for design excellence and professionalism. Sean will continue as Director, supporting the practice and our clients in the forthcoming period.

Supported by our management team, Clare’s natural leadership skills will bring new creative drive and energy to the role along with a strong commitment to collaboration, sustainability and creative excellence. With over 25 years’ experience, Clare has led and contributed to some of the largest and most complex projects in the state. Her professionalism and commitment will ensure that OCMA continues to develop and evolve to meet the challenging needs of our industry.

We look forward to this new phase of OCMA’s growth as we continue to lead in creating inclusive, enduring and high-quality architecture.
