Nearly 100 businesses and organizations (see list at bottom of page), with leaders representing more than two dozen countries, have trusted Susan Ennis for her wise counsel and actionable insights. Hear what some of her clients say about their work together.


Susan Ennis came to Decibel to do a very sensitive task: provide leadership performance feedback and solutions to the CEO and BOD. She partnered well with me as the CPO during this process and subsequent development solutions.

We all appreciate Susan’s intelligence, savvy, practical focus, and willingness to partner with us as we grow.

– Anna Trask, CPO Chief People Officer, Decibel Therapeutics

Susan’s first work for Talaris Therapeutics was to build and deliver a coaching program for high-potential managers preparing them for more senior and demanding enterprise roles. Susan and her team then successfully moved on to run executive team offsites designed to align the leadership team and focus strategic efforts. They used the Hogan Personality Inventory to have a data-based feedback approach for exploring both individual and team leadership strengths and development needs. Susan also coached our CSO. Susan and her team were valuable leadership development partners with Talaris.

– Andrew Farnsworth, CHRO, Talaris Therapeutics

Susan has served as my leadership coach on and off for about 3 years and I cannot sing her praises loudly enough. She was extremely helpful in guiding me through the transition from an experienced manager into an intentional, compassionate, confident, and wise organizational leader. Traits that truly set Susan apart as a leadership coach include the following:

  • Her keen understanding of how personality types affect interpersonal dynamics as well as how organizational politics and culture influence what it takes to accomplish goals and effect change.
  • Her deep empathy with her clients’ situations and her skillful coaching on management of self and others in such contexts.
  • Her candor and practical advice when counseling clients during challenging situations; and
  • Her responsiveness in times of crisis.

Susan has been one of the strongest positive influences along my career path and journey into becoming a confident and wise organizational leader. She is a gem and I hope that many others—both aspiring leaders and executive coaches—are able to learn with and from her.

– Irma Perez, Policy Research and Evaluation Expert

If anyone were to tell me that my boss and I would be working better together, I would have thought they were nuts. Susan and her process have given me the tools to work through better and more effective approaches.

– Coaching Client, Museum Planning and Design Director

As we started defining the TJX Leadership Competencies, Susan noticed how our unique and strong culture was a driving force in TJX’s success. We all felt the pull of the culture but had not articulated it succinctly.

Susan was able to create a simple and compelling description of the TJX culture which resonated with leaders and associates.

These TJX Cultural Factors have become an important tool with our onboarding, executive selection, and leadership development efforts.

– Global Head of Leadership Development

Susan first worked with Decibel in 2022 as she pulled together my 360 evaluation and development plan for the BOD.

Susan’s astute political sense and organizational savvy identified critical issues for the company and me to address.

Subsequently, Susan provided critical 1-1 coaching and worked with Decibel’s senior management team on their mutual understanding and learning to collaborate as a team of enterprise leaders. She has been a truly valuable resource to Decibel.

– Laurence Reid, CEO, Decibel Therapeutics

Susan has been a strategic leadership development partner and executive coach to numerous clients throughout her career.
