Liz Hurst

VP Marketing

Liz has pulled off the dream of thousands: finding a way to turn work she loves into work that serves.

After a wake-up call in the form of a seriously ill family member, Liz left a twenty-year communications career with some of the leading advertising agencies in San Francisco. Her aim was to align her values with her work life, give back and right-size family. To our delight and great benefit, Liz chose to join Summer Search. She helps us tell our story to the world with flair, clarity and heart.


Liz graduated magna cum laude with a BA in business economics from the University of California, Los Angeles. (Go Bruins!) When she isn’t spreading the good word for Summer Search, she loves to hang out with her large extended family, devour good books and eavesdrop on her two little girls when they are playing, especially when one of them is appropriating the role of “mom”. 

Liz and her family live in Marin County, California, in an old-fashioned neighborhood where kids walk to school and people routinely borrow cups of sugar from their neighbors.

Peter Retzlaff

Executive Director, New York City

Following a number of years running his own business, Peter began his journey in the nonprofit sector after deciding he wanted to do work with a more permanent impact on the world around him. Now, more than a decade into his career in youth development, Peter is motivated by the trajectory shift that can occur in a young person’s life as a result of intentional, high quality programming. The belief that the most profound impact of this work is that the benefits will continue to reveal themselves over years, lifetimes and even generations of families is a critical driver to what we get to do in this field.


Prior to Summer Search Peter led Community for Youth, a life-skills and mentoring program in Seattle where he lived for many years. In Seattle Peter also did extensive work with Youth Development Executives of King County, The Weikert Center’s Youth Program Quality Assessment tool, and Washington State Mentors Quality Mentoring Assessment Pathway Taskforce all of which worked to elevate the impact of mentoring young people. That work, seeing the incredible results that uncommonly intentional and professionalized mentoring yield, elevated the type of program that he wanted to work with. A move back home to the east coast brought him eagerly to Summer Search NYC.

Peter’s commitment to social justice extends beyond the workplace to a number of Boards and other volunteer opportunities including Fremont Community Therapy Project, Providence Hospitality House and work in King County Jail and Monroe State Prison. Now in NJ/NY after more than 20 years out west, Peter is looking forward to getting re-engaged in the local community. And in the days between there is always more live music to check out, more books to read, and more movies to see.
