GREG PHILLIPS
CMCA, AMS
President, Community Association Manager
In 2013, Greg Phillips accepted a job working as an administrative assistant in a community association management firm. In college at the University of Missouri - St. Louis at the time, Greg was looking for any job he could find to earn some money while studying for his Bachelor's degree in Public Policy and Administration. He didn't know it at the time, but this job would soon turn into a successful nine years and prove to be one of the most valuable decisions he ever made. At the age of 19, Greg had stumbled his way into a true career.
​
In the time since, Greg has managed dozens of associations both in Missouri and Arizona. He has worked as a Community Manager, a Senior Manager and Director of Marketing and Client Services. He has consulted for more than two dozen independently managed community associations and gained great experience making him one of the most highly skilled managers in our market.
Greg holds the Certified Manager of Community Associations (CMCA) certification awarded by the Community Association Manager's International Certification Board (CAMICB). At the time it was awarded he was one of the youngest managers in the United States to ever earn such a designation. Greg also holds the the Association Management Specialist (AMS) designation from the Community Associations Institute (CAI) and is working towards his goal of obtaining the Professional Community Association Manager (PCAM) certification, the highest level certification offered. Greg also studied for and received his Missouri Real Estate Salesperson's license in 2017, however he does not practice and focuses his efforts on the successful management of community associations.
​
After working for several association management companies over the course of his career, Greg identified a plethora of shortfalls in how these organizations operate which results in a less effective and enjoyable experience for their clients. In 2021, Greg decided the most effective way to provide an exceptional experience to the associations he manages would be to go into business for himself.
​
Greg founded G.S. Phillips & Co. to provide our St. Louis communities with the proven association management solutions they truly deserve. He focuses on fostering condominium, townhome, villa and single family homeowners associations of all shapes and sizes into truly dynamic communities. Through the use of sound financial judgement and the implementation of tried and true processes, along with the adoption of advanced technologies where appropriate, Greg has a proven track record of delivering clients the opportunity for perpetual success.
