After graduating from the University of Washington with a BA in Social Science, I began my employment with City Light.  My father was a prominent self-made electrician during his lifetime, and my work at City Light provided an opportunity to share a common interest at the dinner table. 

I have been on various boards and committees at the City of Seattle for nearly 20 years. I served as President of City Light’s Black Employees Association, an Employee Survey Strategy Team Member, an Employee Assistance for Seattle Employees Trustee, a Combined Charities Coordinator, a Trustee and union steward for what is now PROTEC17  (through its evolutions with other labor organizations)  as a  Mayor’s Race and Social Justice Core Team Member, and City Light’s Race and Social Justice Change Team Member. 

I ran for Seattle’s Civil Service Commissioner because I believe my 20+ years tenure with the City of Seattle and my dedication representing employees’ interests will make me an asset for employees on this board. I believe I can help contribute my personal work experience in the city on this board improving training, opportunities, and fair outcomes.
