Our hand picked team of consultants at Castalia have coached and trained some of the most senior level corporate PAs from the UK, Dubai, South Africa, India, Holland, Germany, Sweden, Norway, Spain, Russia, Nigeria, Thailand, the Philippines, Vietnam, Brunei, Indonesia  and Malaysia. We run our programmes globally in order to take our experience to PAs all over the world.    We actively support and build strong links with other organisations who are dedicated to the professional development of Executive Assistants and PAs.  

We are a team deeply committed to ensuring the complex development needs of senior level assistants are met and bring together all of our PAs under the umbrella of The 100 Network; a truly global social network of senior level PAs to continue to exchange ideas and share best practice.

Gerry Hyde, Executive Assistant to Susie Barron-Stubley

Gerry is, without doubt, the most important person on the Castalia team!!  Whist trying to keep a sometimes over enthusiastic Susie on the straight and narrow and in the right place at the right time, she charms clients, consultants and suppliers and ensures the smooth day-to-day running of Castalia and ensures everybody has the right information at the right time and is in the right place!

Gerry has over twenty years experience working in corporate and with SMEs in the capacity of Office Manager and Executive Personal Assistant.  Her background includes industries from retail, facilities management and the training arena.  Prior to joining Castalia Gerry worked for ten years for a Sales and Management Development organisation and this has given her a vast knowledge of the training industry and complements her creative and organisational skills.  Gerry is always keen to help others, is extremely reliable and enjoys being involved in new projects.  Her organisation skills are captured in the seamless day-to-day running of Castalia.


Lindsay Thompson, Associate Director of Coaching

Lindsay has a corporate background with 11 years’ experience supporting at Board-level within global organisations including ConocoPhillips and Deutsche Bank. Fluent in German and now rusty in French, her background in languages has always provided an added perspective to Lindsay’s work, particularly with regard to communication and understanding – not only between foreign cultures but also between management levels and groups within the workplace. Lindsay believes that coaching as a management style is crucial for the future of business as it encourages input, creativity and growth, fostering understanding and allowing us to learn from each other. Ultimately, great coaching has much wider implications as the ‘ripple effect’ carries our learning and respect for others outward, beyond the people immediately surrounding us.


Carolyn Gilligan, Senior Training Consultant


 Carolyn joined Castalia in 2006 as our senior Executive PA Training Consultant. Her area of specialism is supporting senior level Corporate PAs to develop their social and business skills and leads our exclusive one-day public training programme on Business Etiquette and Protocol for Corporate and Private House PAs. Carolyn brings a wealth of experiences to our clients; including her experience of supporting many high profile individuals in private and public organisations herself. She is a respected speaker at many major PA Conferences and Seminars and is the author of 'The Role of the Executive Secretary', and is currently writing a series of handbooks covering a wide range of topics addressing the development needs of Executive PAs.



Lucy Blenkinsopp

Having enjoyed a successful career in the fashion industry and as a model, Lucy is using her considerable talents to the benefit of Senior PAs and now works as a qualified Image Consultant. Lucy specialises in supporting senior PAs and EAs to present themselves appropriately to operate with impact and flair at Executive level. Lucy's ethos is based on the proposition ‘Be the Best you Can’ and understands that it is, at times, a challenge for senior PAs to demonstrate the authority and responsibility they hold within the organisation. Presenting yourself in the appropriate style and business dress to fit your own personality and organisation will take you a long way in achieving that goal.
