I work with executives, entrepreneurs, and curious humans to examine themselves and the world around them so they get to do what they really want each day with more boldness, joy, and purpose. 


I’ve coached over 150 leaders including executive officers, solopreneurs, start-up founders, doctors, lawyers, creative directors, non-profit directors, college professors, retirees, venture capitalists, and other coaches. 


Prior to coaching, I’ve walked the path of a start-up founder, corporate leader, and ceramics artist. I've lived and worked across the world on four continents. I'm a deep generalist who has worn the hat of a CEO, scaled two venture-backed companies (one is now a public company), and worked in numerous industries across climate, hospitality, on-demand delivery, and international development. 


My purpose is to serve humans openly and deeply. My worn-many-hats life has allowed me a deep appreciation, respect, and empathy for the nuance and complexity that my diverse clients bring to their work.


I hold a BA with distinction from Yale, a MBA from MIT Sloan (where I was a Siebel Scholar), and trained with the Hudson Institute of Coaching. 

Client Testimonials

John | VP Product

Mo | Physician & Stanford Professor

Medora | Founder & Entrepreneur

Jeff is a really special listener. He brings curiosity and openness, as well as a willingness to share perspectives sourced through his own experience of self-discovery.  When exploring my inner life, musings, and struggles together during coaching work, I've found Jeff to be a much-valued, much-welcome companion. He's challenged me and pointed my attention to interesting, productive places.

Medora | Founder & Entrepreneur

Jeff is unrelenting in his desire to help his clients unearth truths about themselves and how they want to show up in the world. He probes to get to the underlying, often truer answers during sessions, and he is a great partner in pushing his clients to think through their motivations. Our work together helped me shape a lot of the thoughts about what I wanted my next career move to be. He helped me think through how I want to show up in the world and translate that into action.

Shelley | Economic Development Leader

If you are lucky enough to encounter Jeff in your life, consider yourself a privileged person. I had the opportunity to work with Jeff last year. In a very short period of time, he helped me realize what things were important to me and how to reprioritize life goals. He is incredibly friendly, kind, non-judgmental and most importantly, talented at asking the right questions to help guide you.

Jeff is a remarkable coach whose essence is defined by kindness, positivity, openness, intelligence, and unwavering support. With his warm and empathetic nature, he creates a safe and judgment-free space for his clients to explore their goals and aspirations with thought-provoking questions and active observations of his clients, listening with a present mind and heart.

Devin, Data Engineering Leader

Jeff is a very talented coach: he's kind, he's smart, and he's helpful.  I've been able to better manage my professional obligations, make smarter decisions, and have found ways to maximize the parts of my job that I love (and minimize the parts I don't). I'm happier, less busy, and more satisfied in terms of what I get done.  I'd work with him again in a heartbeat.

Devin, Data Engineering Leader

As a coach, Jeff met me without judgment, and was ready to dig into the challenges I was facing. I can now more easily identify when fear and negative emotions are holding back my best-self, and I have new tools to manage and work through them. I find myself a wiser leader for my organization, a stronger coach for my team, and a healthier influence on the people and friends around me.
