Developing Leaders, Managers and Teams

Callander Associates Limited

Established in 2009, this company has enabled Mary and Simon to work together on a range of projects either as a team or as individuals. Key delivery areas include:

Interim Management - for both statutory and third sector organisations. As experienced strategic, operational and senior managers we are skilled at picking up complex pieces of work, delivering on time and on budget.

Management and Professional Training - we design and deliver bespoke training courses for organisations delivering on internal priorities and ambitions for the future.

Coaching and Mentoring - we offer tailor made packages to individuals from a range of backgrounds and organisations e.g. Headteachers, Authors, Chief Executives, Therapists.

Project Work - we have substantial experience of carrying out specific reviews/projects for agencies including: Voluntary Norfolk, Suffolk YOS, Suffolk Constabulary, Norfolk Criminal Justice Board and the Ministry of Justice.


Team Development - utilising group dynamics and non-verbal communication we work with teams to increase their effectiveness by ensuring that the contribution of each individual is valued and understood. How do you engage the "difficult" member of the team who is actually your greatest asset?

Individual Hypnotherapy work - sports performance e.g. preparing for a marathon, confidence building, relationships etc.

Relaxation and Hypnosis - courses designed to suit particular needs including those recovering from illness.
