OAS Management, LLC, “Serving Community Associations” since 1984, was formed with the goal of offering exceptional service at fair and competitive prices. We have been providing personalized financial and management services to Homeowner Associations in Sonoma County for over 25 years.

Over the years we have honed our skills and organized our personnel and our office, utilizing the most excellent technology available, to provide the best quality service possible. We have a very strong emphasis on Accounts Receivable and financial accounting for Homeowner Associations. In addition, we offer full-service Association Management, intended to relieve the Board of Directors of the day-to-day Association administrative functions, without diminishing the power of the Board.


We are pleased to offer Homeowner Association websites, in cooperation with our accounting and management software provider. The integrated websites allow all members to be well informed about Community events, pay dues on line, submit accounting or service requests, access Association documents and foster a sense of community with the Association.



We currently serve 42 Homeowner Associations in Sonoma County. We have a conscientious, friendly staff and look forward to working with your Homeowner Association. Your call to our office will always be answered by our pleasant and competent staff.

Serving Community Associations” is our desire and our goal. We understand that your home is your investment, and desire to assist the Board in maintaining and protecting your Homeowner Association. We welcome the opportunity to assist you with your needs in administration, accounting and management of your Community.
