My Expertise

ICF Professional Certified Coach | CTI CoActive™
Masters of Human Behavior | Landmark Education Graduate

For over 25 years, my intuitive insight, strategic perspective, and unwavering belief in human potential have been the mainstay of my success — and resilience — as an executive thought leader, coach, and consultant. Known for my direct yet compassionate approach, I create an environment where leaders can confront challenges head-on, unlocking both professional breakthroughs and lasting transformation.

I specialize in helping leaders who excel as managers, but need to elevate their executive leadership skills to thrive as key stakeholders within their organizations. My approach strengthens a leader’s foundation by equipping them with the tools, insights, and practices needed to navigate their ever-evolving leadership environment. My clients consistently report significant growth in presence, self-awareness, confidence, ownership, influence, innovation, strategic acumen, and overall performance.

Prior to launching my coaching practice, my diverse business experience included leading teams in 23 countries worldwide, managing budgets that supported half-billion in annual revenue, launching multiple award-winning product lines, driving consecutive record-breaking increases in divisional performance, and spearheading the development of best-in-class training programs. A consistent go-to executive resource, I deliver a unique combination of macro perspective with micro sensibility and practicality.

I have sat on the board of, and been involved with, over 15 start-ups, charities and industry organizations. A dynamic and diverse professional, my expertise spans a myriad of industries including finance, healthcare, technology, publishing, retail, and entertainment, including coaching leaders globally at organizations such as Yahoo, Realtor.com, Fortinet, Stanford Medicine, Wyndham, Travel & Leisure, Blue Cross Blue Shield, Kaiser Permanente, among others.

I am a distinguished masters graduate of New York University, ICF Professional Certified Coach, Co-Active® trained coach, Landmark Education graduate, NGLCC certified diversity supplier, and prolific philanthropist. My passion for both professional and social development is only matched by a passion for living my own life boldly.
