Meetings are held on the third Wednesday of each month at Kaiser Hospital, 975 Sereno Blvd., Rooms A & B, Vallejo at 7PM.  No meetings are held in July or December. 

Our meetings are as much informational as social.  Most meetings provide a medical lecturer or an ostomy supply vendor or a presenter on a life subject. 

We are dedicated to the rehabilitation of ostomates through mutual aid, moral support, education and providing practical information. 

What is an ostomate? 
Ostomy:  An abdominal opening for elimination of bodily wastes.  An ostomy may be a colostomy, ileostomy or urostomy to correct or bypass a disease process or internal injury.

The OAS is an organization of volunteers who present living evidence that ostomy surgery need not interfere with work, marriage, family, travel or recreation.
