About Questline

We provide expert guidance to your organisation, teams and leaders through bespoke, human-centric talent development partnerships. Our solutions are cost effective, convenient - because time is precious - and have a longer term impact so you can make more progress.

Our Vision

Making a positive impact one partnership at a time!

We strive to cultivate a supportive development environment with people at the heart of our partnerships where non-judgement, confidentiality and empathy are central. We also like to have fun along the way – because time is precious, learning and growing is exciting and development should not be painful.

Our Mission

LEADING the way towards a future where your individual and organisational impact is understood and maximised  and barriers minimised – partnering with you whilst you make more PROGRESS..

We believe the first step towards meaningful change is awareness and learning is more valuable if gained through experience. We exist to help you gain insight of your true impact, your hidden opportunities and underused strengths – ensuring any potential barriers to momentum are reduced – helping you make more progress.

We do this by creating and cultivating the environment for leaders to be supported and teams to be developed in problem solving and decision making in order to make sustainable progress.

Purposeful learning through experiencing, doing and reflecting
Progress that is continuous and sustainable

Our History
In 2007 the Questline practice was set-up to work with large-scale, global clients who were facing change.
In 2013, the business was oriented to broaden our reach, increase our impact and focus on Organisational Performance, Personal Development and Leadership Coaching as our primary offerings whilst still drawing upon our vast consultancy and leadership experience.
Since that time, we have worked with global institutions, educational organisations, medium and small business and individuals.

Stephanie Nellis

I am passionate about collaborative leadership and the power of learning through doing rather than through theory. I believe that leadership is an art which cannot be taught through theory. Each leader needs to develop their own formula for dealing with issues, for communicating and for achieving the performance of their team.

I focus on creating the environment for leaders to develop that formula in a challenging yet supportive environment.

As a facilitator and coach, I am calm, empathetic and approachable. I know when to intervene but more importantly when to say nothing at all, even during those awkward silences to allow amazing things to unfold. There is nothing more rewarding than to be quietly witnessing great leaders grow in front of your very eyes.

My previous experience as senior manager means that I have witnessed first-hand the daily challenges of leadership and have experienced the impact that great leadership development initiatives can make on individuals, teams and organisations.

In my spare time I enjoy spending time in the great outdoors and the peace that it can bring (if both dogs and both children are in the right mood)!

Steph is an accomplished team builder and developer of people.  I have seen her work with new and existing teams, successfully supporting and leading their transition from the formation or ‘crisis response’ stage to stability and performance.” MS, Senior Manager

Anthony Nellis

I love working with forward thinking organisations, teams and individuals who want to learn, develop and make real progress. I emphasise strengths rather than weaknesses and have found that raising awareness and reframing challenges can save lots of emotional and physical energy which can be diverted in meaningful change and more impact.

I believe change and transition should ultimately be an exciting and rewarding experience, rather than one to fear and dread. This is a firm foundation in my partnerships ensuring delegates are relaxed and at ease therefore more likely to embrace and sustain the learning.

As a performance coach I strive to create a culture of growth and progress and am not afraid to challenge and support delegates, teams and organisations in the spirit of enhancing their development journey.

My experience working in agile transformations has influenced my applied methods which centre around sustainable progress and I have worked with senior management, Educational Leaders, business owners as well as being a Mentor with VirgingStarUp, helping new businesses to succeed.

In my spare time I enjoy triathlon and am currently going through the British Triathlon Coaching accreditations.
