Hi, I’m Ann-Marie.
I am a leadership coach with over two decades of experience in neuroscience, psychology, leadership and organizational development. I customize a solution to your specific situation to unlock your leadership potential.
I work with high-potential individuals to
unlock their next level of leadership.
Entrepreneurs
Running a business can be a wonderful and empowering experience. I work with clients to transform and fulfill their leadership potential, grow their business and balance meaningful relationships.
C-Suite & Senior Leaders
My clients include executives and senior leaders from SMEs to fortune 500 companies. I work with clients to figure out their strengths and how to manage the levers around them to drive impactful change.
Emerging Leaders
I help ambitious leaders identify their gifts and what is holding them back from achieving their potential. Together, we chart a path to positively impact their work, achieve their goals and grow in their career.
Leadership is personal - your coaching should be, too.
I customize a solution, specifically for you. Together, we’ll build a relationship and make progress on your goals. I’ll guide you to identify strategies to maximize your strengths and approaches minimize and manage your limitations to unlock your full potential as a leader.
I work with the whole individual. And as this past year especially has taught us, all areas of our lives can impact how we show up at work. Everyone adapts to and is part of different systems - our native culture, our family culture, our business culture, our team culture. To bring out the best in you, we’ll understand how all areas of your life can be integrated to achieve purpose and clarity to maximize your impact and grow your business.
We’ll design a roadmap and make informed decisions together. I’m the right fit for you if you’re looking for a partner and a hands-on collaborator to help you navigate your unique situation - rather than a cookie-cutter or general formula.
As a Chartered Organizational Psychologist and Associate Fellow of the British Psychological Society, I’ve been helping clients ranging from solo entrepreneurs to Fortune 500 leaders for over two decades. I know what it takes to understand and use self-knowledge to personalize an approach to manage your personal relationships to propel your professional success to the next level.

What My Clients Have To Say
“Ann-Marie brings a refreshing blend of empathy, realness, and organizational strategy to coaching. Upon my very first meeting with Ann-Marie she quickly recognized that I was harboring some unresolved trauma from past work experiences which were hampering my growth and confidence. Her ability to address and make space for reflection and healing allowed me to move past pervasive hurdles and step into my power. In just a few sessions I had reclaimed my confidence, established stronger boundaries, and was able to more effectively recognize and apply my strengths for the greatest impact. Ann-Marie's expertise in organizational psychology brings a wealth of understanding for workplace dynamics and how to operate most effectively within them.”
— Lauren M. M.A., Entrepreneur
“Working with Ann-Marie has changed my life! Her thoughtful guidance has unlocked my confidence in a way that was otherwise not accessible to me. There has been a noticeable difference in how I show up at work and, more importantly, how I feel about my role and myself overall. Ann-Marie strikes a balance between giving just enough to feel supported, and space to take it forward on my own. She genuinely cares about me as a whole person, not just how I’m progressing in my work, and delivers her message with kindness and her feedback with grace. I always feel a calm sense of renewal and a resolve to tackle the next challenge after our conversations. She came into my life at the exact moment I needed her, and I couldn’t imagine continuing in my career without her.”
— Marica R., Manager, Acumen
“I have known Ann-Marie Costelloe for more than 10 years and am so grateful for her insight and understanding. She is the Mary Poppins of the executive suite. Whether serving on a board, working with a non-profit organization, or engaging in business, Ann-Marie’s insight has been invaluable. Ann-Marie identifies group dynamics and individual motivations with a simple clarity, allowing her clients to see through biases and tendencies that can cloud thinking and judgment. Ann-Marie’s deep intuitive understanding of people shines a light on an organization’s group dynamics, helping one to interpret the subtle subculture more clearly, as well as the motivations and unacknowledged intentions of others. This acuity allows for better strategic planning, organizational development, and conflict resolution.”
