Bonnie Wan

Partner, Head of Brand Strategy

GS&P has been Bonnie’s agency home since 1998, where she has led strategy on the California Milk Processor Board (“got milk?”), Comcast, Nest, Adobe and SONIC Drive-In, as well as provocative, effective and award-winning campaigns fighting child sex trafficking, cyberbullying and college-campus rape. 

A graduate of New York University, Bonnie began her career at Weiss Whitten Carroll Stagliano, a boutique agency specializing in luxury brands. From there she worked in the pre-TBWA offices of ChiatDay, where she helped launch Sony PlayStation. In 1996 she moved to San Francisco and began a search for a new agency home, a journey that led to pit stops at Hal Riney & Partners and FCB before she landed at her beloved GS&P.  

Beyond strategy, Bonnie has been integral to the agency’s training and development. As a co-leader of GS&P Ed, Bonnie created the agency’s inaugural management-training course in 2013. She also guest-lectures at the University of Oregon and Stanford’s d.school and teaches an internal workshop at GS&P on writing titled “Your Life Brief.” Bonnie’s ultimate passion and drive is to create an environment in which people are energized to do their best work and bring their whole selves.  

Bonnie was named an associate partner in 2014 and a partner and the head of brand strategy in 2016. 

She lives in San Anselmo, California, with her husband and four kids.

Brian McPherson

Managing Partner

For 20 years, Brian has been happy to call GS&P home.

Over that time he has led accounts in nearly every major category, from banking to telecom to technology to packaged goods and most things in between. He has been involved in work that has won many times over for creativity at Cannes as well as for effectiveness at the Effies. He currently leads the Frito-Lay and Adobe accounts at GS&P and is particularly proud of these long-standing client relationships of more than 10 years each.

Since 2007 Brian has also run the account management department. He enjoys overseeing the direction of the department, developing its people and recruiting and training new talent. He’s interested in how advertising is evolving and what that means for modern-day account work. He has written often about both subjects in a number of industry publications, including Ad Age.

Brian considers himself lucky to have grown up at GS&P, where he scored his first job after completing his MBA in marketing and finance from the University of Arizona and his undergraduate degree from Queen’s University in Canada.

Outside of work he spends his days in Mill Valley with his wife, Kate; his golden retriever, Moose (who, they swore, would never sleep on the bed but does); and his newborn son, Henry.

Leslie Barrett

Managing Partner

Born in Zurich, Switzerland, Leslie moved to the US at the age of 13. She began her advertising career at Anderson & Lembke, where she worked on Microsoft for three years. 

During her 20-year tenure at GS&P, she has led the Wall Street Journal, SBC, HP, Emerald Nuts, Subway, Denny’s, Logitech, TD Ameritrade, Nickelodeon, SONIC Drive-Ins and Häagen-Dazs accounts. 

Barrett’s teams have consistently developed work awarded for both creativity and effectiveness. She currently oversees the BMW, HP, Comcast/Xfinity, PayPal and One Medical accounts, among others.

Over the years Barrett has led a number of the agency’s new business wins and, as a result, became director of new business in 2014. She was named a partner in 2016.

She lives with her two daughters in Mill Valley. It’s beautiful, but it’s no Switzerland.
