Parker Callister, Partner

Before co-founding CallisterHaag Consulting, Parker spent the bulk of her career in banking with two of the largest financial institutions in the country. Starting in New York City, over the years she went from corporate banker to ever increasing levels of management including a four year posting to Santiago Chile where she was the Managing Director and Country Manager for the US institution that was the country's largest foreign investor at the time.

A hiatus brought her to San Francisco to obtain a Masters Degree in Counseling Psychology spurred by her long standing fascination with human behavior and group dynamics.

A seasoned, decisive and versatile key executive John has a strong track record of creating vision, executing strategy,  and delivering results while under pressure, through strong leadership and determination.
