I believe that everyone comes into this life with a purpose and I truly love helping people define their mission, embrace their core values and explore a bigger vision. This is a fundamental starting point for working together, from there, we can do anything!

I am honored to accompany and guide you on the adventure while providing inspiration and support along the way! That means thinking in unlimited ways and creating grounded practical steps with tangible results.

Before I started coaching, I spent 25 years in senior leadership roles overseeing marketing, corporate communications, sales operations, training and business development in a few large corporations. I learned a ton, made significant contributions and loved many of the people and projects I led. Along the way, I adopted a sweet baby girl from Vietnam and found myself in the throes of downsizing, consolidating, rightsizing, – use the word you like best – one too many times. As a single mother and successful executive in corporate America, it was a time to acknowledge “been there, done that, now what?” So in 2010, I walked away from the corporate grind, donated my business suits and chose to listen to my heart and follow my bliss by starting a business helping others find and thrive in the work and life they love. Since then, I have helped 100’s of people embrace their core values and create a mission statement and vision statement. From there, we’ve taken the steps to implement their business, find their ideal job, better navigate the corporate world or simply feel better by embracing their life purpose.

My many years of leadership experience, education and intuition have been a wonderful foundation for working with my clients. I have an M.A. in Sociology from DePaul University, and a graduate of Northwestern University, Kellogg School of Management’s Executive Development Program. I have completed course work in Path Coaching, Living Intuitively, Creative Problem Solving and certified in the FourSight Thinking Profile.

My mission is to enable people and organizations to live their purpose and move forward with clarity, courage and strength.
