Seatle Operating Support has been an excellent association management company for us.  We are a small group, and volunteer run.  There are often long periods of no activity on our part.  There is no stress for us because we have trust and faith in them to stay on top of things.  They have never let us down.

Chuck LaFlamme, MAIAppraisal Institute, Region 1 Chair

SEOPS has been instrumental in our efforts to inform appraiser’s throughout the state of legislative issues and education events.  Our association with SEOPS has allowed our organization to focus on our missions by relying on them to keep our accounting and meetings scheduled.

My name is Mike Opitz. I have been President of the Puget Sound Carwash Association for the past four years. Throughout this period I have worked closely with Elly Snow and here entire staff at SOS. I can unequivocally say that without SOS there is no way I could have managed the role as President of the Association. The efforts of Elly and her staff were instrumental in all that we have accomplished over the past four years. They executed flawlessly 90% of the work that had to be done. In addition to managing the work flow and the day to day operations of the association, Elly consistently brought to the table innovative ideas directed toward accomplishing our goals. I, without hesitation, highly recommend SOS to any organization needing assistance in the management of their operations.
