JJ is a wonderful leadership professional who has devoted herself over the last ten years to her craft as a program designer, executive coach and group facilitator . She has a warm heart and a welcome smile, and leaders feel immediately at home with her. I've seen JJ win trust very easily even with senior leaders who serve companies all over the world.
She also has a great eye for detail in execution and program delivery and can be counted on to foster a sense of inspiration and high touch caring in anything she touches. She is a deep listener and a very candid counselor and a reliable resource for leaders interested in further humanizing the workplace.

I have worked alongside JJ on multiple leadership development and coaching projects for different clients over several years, and she is always a delight to work with. JJ is a deeply attuned listener - also to what remains unspoken - and has a remarkable ability to translate client needs into bespoke offers and programs with ease. Even while holding multiple projects at once, she remains fully present, responsive, and fast to execute.
