“Marni is an exceptional executive coach. She and I worked together during a 15-month period in which I was taking on a new, more challenging, and more complex role than I had ever had before. Marni helped me navigate the key challenges in that role with tremendous curiosity, empathy, and expertise. She brought effective tools to bear and helped me tailor them for my specific context. I can say without a doubt that I’m more successful in my role because of her!”
“Marni’s holistic and integrated approach enabled me to excel in a period of rapid advancement involving brand-new territory: to servant lead a team of 60+ amidst tremendous change, while balancing all the facets of running a successful business. She has been a force of growth, accountability, encouragement, and inspiration to me for over a year now. Marni challenges me, coaches me through crucial decisions and provides an avenue for processing some of the biggest professional hurdles I’ve ever encountered. She has been invaluable to me as a leader.”
“Marni enabled me to find clarity, regain my purpose — and course-correct into my desired fulfillment. There are pivotal times professionally when you realize that you’re not on the right path to fulfillment. You think you are—and outside influences lead you to believe you are—but you’re not! Through discussions with Marni and her suggested readings and tips, I had a massive epiphany. The ‘thing’ professionally I was manically driving towards, and thought was my end desired state, wasn’t my end game at all.
Once that clarity took hold, the new path forward revealed itself. I couldn’t be more grateful … and happy! If you’re like me and desire to consistently reevaluate, refine, and elevate your thinking and tool set, there’s no better executive coach to have by your side than Marni.”
