The JK Educate Team

Led by co-founders Lorrae Jaderberg and Katie Krais, we offer a premium education service, with tutors that have a passion for teaching and a deep knowledge of how to help a child reach their potential. We have a dedicated monitoring team and a team of behind-the-scenes staff working hard to ensure that our clients’ experience is that of being well supported and cared for, whilst achieving optimum results.



Lorrae set up JK Educate with Katie in 2010, to fulfil the vision and belief that every child should be given the opportunity and encouragement to achieve to the best of their ability and potential.

Lorrae has over thirty years’ experience teaching in primary schools in London, with five years spent in senior school management, including as a Deputy Headteacher, SENCO and Gifted and Talented coordinator, whilst continuing to create and publish educational programmes for schools. As an assessment co-ordinator, she trained staff in improving pupil achievement, created and developed whole school assessment programmes, pupil tracking systems and data interpretation. This experience helps her oversee the dynamic training and monitoring that is so crucial to JK Educate’s high standards.

Lorrae lives in London and is married with four children. Read more



Katie has an excellent understanding of the information parents need to have to make an informed judgement about the ability of their children and how to move them forward and get the best education available. Her passion for this process and the importance of finding the right school for every child formed part of Katie’s motivation for setting up JK Educate with Lorrae, to help families successfully navigate their educational journeys.

Katie has twenty years’ experience teaching in primary schools in London as well as being a published author. She has been year group leader, assessment co-ordinator, teacher governor and a member of school senior management teams, as a SENCO and Inclusion Co-ordinator. These experiences help her guide the JK team to provide the support that families need.

Ruby Holmes



Ruby joined the JK team as an assessment administrator and has now taken on the role of providing a key point of contact for both clients and tutors.

Once the ideal match is achieved, Ruby liaises with the client and tutor to set up the tutoring arrangements and goes on to manage any future changes to tutoring schedules and requirements.

Ruby has spent four years working as a higher level teaching assistant at an outstanding primary school in North London prior to joining the JK team and has also spent time in Thailand and Philippines volunteering as an English teacher. In her spare time, Ruby loves running, cooking, baking, crafts, travelling around the world and heading back home to the countryside where she grew up.

One of Sasha’s key tasks is carefully matching students to the best tutors for them, by working closely with Lorrae and Katie and using their in-depth knowledge and recommendations. Once the ideal match is achieved, Sasha liaises with the client and tutor to set up the tutoring arrangements and goes on to manage any future changes to tutoring schedules and requirements.

He combines his time at JK with his role of Bursar at a private college in West London, where he also tutors in Accounting and Business.

Tunde is married with two daughters and he can certainly empathise with the anxieties experienced by parents as their child strives to climb the ‘educational ladder’. In his spare time Tunde tries, often despairingly, to defeat the computer at chess and to utilise his latent DIY skills.
