New York’s senior leaders operate in one of the most demanding, high-stakes environments in the world. Deeply capable, they’re under constant pressure and rarely afforded the space to reflect, reorient, and renew.

New York’s leaders find me when the stakes are high and the usual playbook isn’t working. They leave with:
These are outcomes I consistently see working as an executive coach New York leaders rely on at critical moments.
“I have been using Kate’s leadership coaching services for only a few months, but in that time she has – quite literally – changed my life. Kate has an uncanny ability to see beyond the immediate issue, and makes me think very deeply and reflectively about my own practice. In fact, I have learnt things about myself that I had no idea about! While not always comfortable, Kate makes me consider things from different angles, finding alternative solutions to issues that sometimes feel insurmountable.”
While I partner with clients across the US, I maintain a presence as an executive coach New York leaders turn to – offering both in-person and virtual engagements. Many clients appreciate beginning and concluding their coaching with face-to-face sessions, meeting in person once a month with additional sessions online, or tailoring the rhythm to fit their needs. Whether navigating transition or seeking deeper strategic alignment, leaders value the discretion and presence I bring to every conversation.
For the past two decades I’ve coached leaders around the world and across the United States. I am now accessible as an executive coach New York leaders can meet with locally or virtually. My role is to be your most trustworthy partner, sharing with you what others won’t say – to support you in leading with strength and composure under all circumstances.
I partner with leaders across the US, from New York to Silicon Valley, with some clients in Europe and India. The majority of my coaching is done virtually with some face-to-face clients in Manhattan and Greenwich, CT. Additional F2F options are available by request.
I have a Master’s degree in Evidence-Based Coaching Psychology and bring years of experience coaching CEOs and senior leaders. My approach is informed by coaching psychology and grounded in sustainable outcomes – not motivational fluff or generic advice. I also have years of experience partnering with internal HR and People teams, ensuring positive results for both the leader and organization. If you’re searching for an experienced executive coach trusted by intelligent professionals, let’s check for fit.
My clients consistently experience greater clarity, calm, stronger executive presence, and higher team engagement. They come to know themselves better than ever before, lead with more authenticity, and make confident decisions – even in high-stakes environments.
