Education Consultancy

Will Orr-Ewing, Founder and Director

Will attended Harrow School before undertaking a degree in History at Oriel College, Oxford. After graduating he was a History teacher at Fulham Prep School. He has been tutoring since 2005, and set up Keystone Tutors in January 2007. Through his work both in tuition and mainstream education, Will sees clearly why people seek private tuition. Rather than criticising formal education - or suggesting an alternative - Will sees private tuition as an adjunct to it. It should be integrated within the school approach, and appreciate individual styles of learning.

It was through his work that he became interested in learning difficulties too. Will runs a project called dysTalk, which is dedicated to exploring learning difficulties, and sharing information amongst parents.

As well as being a governor of two schools (Westside School and Floreat Free School), Will is an increasingly active participant in the education sector and its various debates. He is a board member for The Tutors' Association and speaks for The Parent Company at institutions such as Credit Suisse and Freshfields. He also speaks under his own steam at Pushkin House, and writes education comment pieces for publications such as Focus Magazine and The Prep School Magazine. He blogs at www.willorrewing.com.

Ed Richardson, Director of Education

Ed read Zoology at St. Andrews University before completing a Secondary Science PGCE at Oxford University. He has since undertaken a Masters in Teaching and Learning at Oxford too. Prior to joining Keystone, he taught all three sciences to GCSE as well as A Level Biology at an outstanding state comprehensive academy in Oxfordshire.

Ed is now our Director of Education, and is primarily responsible for leading our client management team, the tutor recruitment process and generally overseeing our employed tutors' professional development. Ed also advises our families on a wide range of educational issues; he has particular experience with schools and university advice as well as home-schooling.

More broadly, Ed firmly believes that providing tutors with the appropriate levels of training better equips them to support the individual needs of their students. He recognises the value of educational literature and spends time researching current publications, in particular the nature of personalised learning and its benefit to students of all abilities. Outside of Keystone Ed is a Trustee for the Temple Grove Schools Trust and speaks for The Parent Company at a range of different companies on ‘The Importance of Parents in a Child’s Attainment’ and ‘The British Education System’. At the weekends can be found either participating or coaching on a sports field or relaxing in The Cotswolds!

Diana Stewart-Brown, Head of Operations (Singapore)

Diana joined the Keystone London office in 2014, acting first as Office Manager and secondly as Client Manager, before moving to Singapore in early 2017 to set up a new Keystone Office. Diana has worked with numerous families and UK schools since joining Keystone and draws on her extensive knowledge of how the British education system works to deliver bespoke guidance, recommending appropriate and reputable schools and universities and implementing a fitting educational strategy for each student. Diana regularly writes on a wide range of educational topics for the Keystone blog and is also in charge of Keystone’s social media platforms.

Outside of Keystone, Diana is a keen cook and avid reader. Following the move to Singapore, she has begun to travel extensively throughout Asia and developed an interest in Chinese ceramics.  

Jen Ma, External Consultant (Hong Kong)

Based in Hong Kong, Jen specialises in advising families from across South East Asia on UK boarding schools. Jen is a co-founder of ARCH Education, one of Hong Kong's leading providers of tutoring programmes and educational consultancy.

Jen attended St. Paul's Co-educational College and Benenden School, one of the top all-girls' boarding schools in the UK. She was awarded multiple Collection Prizes during her studies at the University of Oxford and graduated with First Class Honours in Economics and Management (B.A., Hon M.A.). In addition to academics, Jennifer was the elected President of the then second-largest student-run society, the Guild, the mission of which was to connect Oxford undergraduates with employment options.

Rhidian Llewellyn, External Consultant

For school placements and consultancy work outside Keystone's core expertise, Keystone Tutors refers to Rhidian Llewellyn and Llewellyn Education.

In 1986 Rhidian joined the staff of The Dragon School, Oxford and, within two years, became Housemaster of School House responsible for 80 11-13 years olds. During his five years on the staff, he taught scholarship English and edited The Draconian, in those days a termly magazine.

In 1991 he was appointed Headmaster of Papplewick, a post he held for twelve years during which time the school flourished academically and culturally while maintaining its reputation for sporting success. At a time when prep-school boarding declined, Papplewick remained consistently full. 

Rhidian left Papplewick in 2003 to establish an educational consultancy for parents, schools and governors. He is a non-executive director of Creative Education Corporation and adviser to Affinity, the leading provider of financial advice to independent schools. He is a governor of three independent schools and chairman of one. He has been an ISI Inspector of Schools since 1995, served on the Boarding Schools Advisory Group from 1998 – 2002, and was appointed Lay Chaplain by The Bishop of Reading in 2002.
