The single biggest problem in communication is the illusion that it has taken place.
— George Bernard Shaw
Our team of communicators, researchers, and health professionals partner with social impact organizations to craft resonant messaging strategies and campaigns that drive adoption of critical products and services in the world's poorest communities. We're believe in a community-based approach that starts with listening.

Meet the Team




Philip leads our projects and organization. After studying engineering at UCLA and working as a tech consultant at Accenture, Philip quit to volunteer on clean water projects in rural Ecuador and China. He painfully discovered that giving people a solution doesn't mean they'll take it. Seeking to fill that gap, he found his calling in the field of social marketing. With environmental firm, S. Groner Associates (SGA), Philip led teams to run campaigns for cities, counties, and agencies in California, including the US Environmental Protection Agency. His work has kept thousands of anglers from eating contaminated fish, stopped youth from littering, and reduced lawn overwatering during California's worst drought ever. He approaches behavior change in a systematic way, and his ability to communicate and build strong relationships has been key to success in his projects and partnerships. Philip started Appleseed to bring what he’s learned back to where he thinks it's most needed: the development sector.



Ruth just loves kids. After graduating from UCLA with a degree in Psychobiology, she completed her medical training at the University of Arizona College of Medicine and the UCI-CHOC Pediatric Residency Program. She is a pediatrician who, before co-founding Appleseed, worked for The Children’s Clinic, a nonprofit clinic for low-income families in Long Beach, California. She loves to serve diverse populations, and has worked in clinics in Mexico, Taiwan, Malawi, Guatemala, and Kenya. She started Appleseed to broaden her impact outside the clinic room. In Appleseed's early projects, Ruth served as a field pediatrician and health adviser. In 2018, Ruth began practicing part-time with Kaiser Permanente in Hayward, California, where she continues to help a diverse array of low-income families.


Alex Pirvulescu, social marketing fellow

Alex is a emergency room and international health Registered Nurse with experience providing care in diverse settings around the globe. She’s worked everywhere from a mobile van supplying injection drug users with clean injection materials to remote communities in Northern Canada and Latin America. After meeting Philip and Ruth in Guatemala and learning about Appleseed’s social marketing approach, Alex began to look at health from a broader perspective beyond the bedside care she was accustomed to providing. Now, Alex has joined the Appleseed team to transform this new perspective into action, merging her medical expertise with her passion for impact and helping people shape healthier lives.


Kelsi Schecter Vahid, social marketer

Kelsi is a health-nerd and musician with a bent for making impact. After receiving her Bachelors in Public Health, she was searching for a way to use her love for the arts to fuel healthy behavior change. That’s when she discovered the field of social marketing, leading her to earn her Master's in Public Health from the George Washington University, specializing in social marketing and health communications. Her love of travel and volunteering have taken her to Central and South America. Now Kelsi is back in Southern California and volunteering with Appleseed, using her knack for research and creativity to create campaigns to motivate people and drive positive behavior change. When she's not doing that, she's probably playing pick up soccer or spending the day at the beach.

Adam dreier, marketer

Adam loves learning.  He was an aerospace engineer for nearly a decade, after studying Mechanical Engineering and Mathematics at SMU. Having made contributions and inventions in the aerospace field, his thirst for knowledge and desire to give back led him into entrepreneurship. The aspect of entrepreneurship that appeals to him most is marketing. Bringing a strong scientific background, Adam works and plays at the intersection of marketing and science, with a focus on direct response marketing. He helps Appleseed because he believes that marketing can and should be used for higher purposes in the world, like improving people's lives. In addition to volunteering for Appleseed, he also consults for Patient Pipeline, a digital marketing agency for medical practices.



In July 2015, Erica joined Appleseed's Board of Directors. Her passion for making a difference and her strategic mind has been vital in shaping our organization and our campaigns. Erica was Philip's principal collaborator at S. Groner Associates (SGA), where she was the Strategic Director of the firm. After successfully running and guiding countless community-based social marketing campaigns to protect the environment, she left SGA to direct her efforts towards improving health. To this end, she joined Health Services Advisory Group to improve Medicare services as a Communications Manager and has recently completed her Masters of Public Health at UCLA's Fielding School of Public Health. Somewhere amidst all this change, she had two beautiful little girls. So, as Erica works from various angles with Appleseed to improve lives, she's doing it at home as well! 


In November 2016, Lily joined Appleseed as a Founding Board Member, advising on  organizational growth while supporting brand management and fundraising efforts. Lily's involvement with Appleseed began as a Founding Sponsor and she also provided guidance during Appleseed’s early stages of development. She brings over ten years of advertising and marketing experience with Ogilvy & Mather advertising agency and Google’s creative marketing team. While Lily loves tackling marketing challenges, she is also passionate about youth mentorship. To this end, she's worked with PENCIL, Spark, and helped launch The Leukemia & Lymphoma Society’s Students of the Year program in LA.



Board Member

Adam assists with legal and financial aspects of Appleseed and helps guide organizational strategy. After graduating law school and getting his MBA from the University of Minnesota, Adam became the Director of Business Development for S. Groner Associates (SGA), the environmental marketing firm where he and Philip first met. The duo bonded over their passion for community and environmental impact. Adam loves kids and is a passionate environmentalist (who maintains a 100-lb vermiculture worm farm in his home). He constantly pushes Appleseed to think creatively about our processes to make sure we're making the greatest impact possible. In co-founding Appleseed, Adam aims to build a strong, nimble, and effective organization that always delivers and exceeds the expectations of our supporters.
