SVP, Operations

Financial Services

"Oonagh and her team approach has made a remarkable shift in our organization. As a new CEO in an organization that was new to me I inherited a management team that struggled both with Positivity and Productivity in both their work and their work relationships. Oonagh became a trusted coach that worked with our team as a team to help us build trust, manage change, learn new management skills and become excited about our work. Oonagh has helped us to dramatically improve both our positivity and productivity outputs across all areas of our organization. "


Not for Profit

    Business Strategy and Execution

    Change Management

Oonagh has a keen sense of understanding how the business runs; the key levers to success and the business results her clients need. She guides them masterfully through a series of facilitated engagements towards the results they are looking for.

All too often organizations embark on large transformational change initiatives, set up a large program structure of project management to guide and direct the work that needs to be done and all too often forget about the structured set of activities that need to be undertaken to successfully move their people through the change to the new desired state. Oonagh has led many such large change management initiatives and has been called upon by the same clients to guide this work for them.


"Oonagh is in a class all on her own! She has a unique ability to guide individuals and teams to the highest levels of effectiveness. She can operate at both the strategic and operational levels - seamlessly transitioning as required. There is no organization that will not benefit from working with Oonagh!"

Chief Global Internal Auditor

Financial Services Company

"I have worked with Oonagh on a number of organizational change management engagements at multiple companies, and can highly recommend Oonagh’s comprehensive and enthusiastic approach to organizational change. Oonagh is professional, energetic, a creative thinker, and an excellent problem-solver. Oonagh possesses and applies a unique set of capabilities in executive coaching, leadership development and mentoring, and change management concepts. She ensures that all levels of an organization understand how they influence and shape the change, how the change impacts them, and the steps the organization needs to adapt to achieve their desired strategic imperatives."

Key tools that Oonagh uses.

A) The Rise of Teams (From Deloitte University Press – Global Human Capital trends 2016)

As companies strive to be more agile and customer focused, organizations are shifting their structures from traditional functional models toward interconnected, flexible teams.

A new organizational model is on the rise: a ‘network’ of teams in which companies build and empower teams to work on specific projects and challenges (agile teams). These teams come together for short periods of time to tackle a problem, then disband and move on to new assignments once the project is complete.


This new program has sweeping implications, forcing programs such as leadership development, performance management, learning and career progression to adapt.



B) Context of teams (excerpt from Team Coaching International)

• Teams exist to produce results – measured by ability to produce results over time

• The way team members are with one another influences the quality and output of results

• System of a team exists as a culture – unwritten rules; beliefs; values; approved behaviours; ‘how things are done around here’

• System of the team is bigger, stronger and more durable than any one individual



C) Relationship Systems Intelligence™ (RSI)

RSI includes and transcends Emotional Social Intelligence (ESI) pioneered by Daniel Goleman and others. RSI starts with an understanding of oneself, (Emotional Intelligence) moves on to include an understanding of other’s emotional experience (Social Intelligence) and culminates with the ability to identify with and collaborate with groups, teams, communities and other social systems (Relationship Systems Intelligence™). It is this final evolution, RSI, which catalyzes the capacity of teams and groups to move beyond the personal to a powerfully generative group identity. Individuals and organizations vary in their level of RSI. Some may need to work on strengthening Emotional Intelligence, others may need training in Social Intelligence and more advanced clients are ready to work with Relationship Systems intelligence™. Together the three forms of Intelligence create flexible, resilient individuals and teams.



Leadership 101 – everything a leader should know



Set a Vision and talk about it all the time – use every conversation to articulate your   vision


Be clear on your purpose – “What is the specific job your clients have hired you to do?” – be really clear about this and advocate for this


Articulate a set of values that are part of your core belief system and that of the team you work with…not just the politically correct ones…’Don’t whine’ is an example of a refreshing    value


Your work is divided into Transactional (day to day business operational activities) and Transformational (those activities you engage in that will move your organization from one level to the next). You need to develop a game plan (strategy) for your transformational work and schedule time to do it otherwise the whirlwind of the transactional will steal that time away


Be clear on your expectations of your people – both work and behaviours


Meet with your people frequently


Model the behaviours you expect – always – you are being watched


Model High Trust behaviours


Be sure always on what your leader expects of you – keep the communication channels open – meet with them frequently – watch for patterns of meetings being canceled – change the day and time to ensure minimal cancellations


Find the right balance of strategic and being in the weeds (too far removed or too close to the work) – if 2 of you are working on the same issue then one of you is unnecessary


Always be looking for your successor – hire your replacement not your clone


Ensure your systems and processes align with what you are trying to achieve (recruitment; performance management; compensation; meetings; communication)


E-mail is not the optimal form of communication and it certainly does nothing to build, manage or repair relationships


Keep close counsel – be sure you are talking about the right topics with the right people – be careful of building a reputation of low trust because of ‘loose conversations’ you may have


Leadership can be a lonely position – find a mentor and spend time with them in close conversations – set it up properly – ask them to mentor and set boundaries for the relationship


Continue to access coaching


Continue to read books and articles about leadership


Schedule time to develop yourself in leadership


Ensure you are involved in one formal leadership development program/course annually


Watch what your Level 3 is telling people – some people have very powerful Level 3 and don’t know it


Articulate your intent in conversations so it is not misconstrued


And lastly floss every day!
