Hi:
There is an optometric assistant training seminar this weekend in San Francisco (14th and 15th).
My co-worker was just talking about it today because the doctor speaking at the event was looking for employees to help check-in people that day. The event is two days (8-5), and I believe the registration fee is around $350.
I will ask my co-worker for more information tomorrow since I can't seem to find anything online about this.
Best wishes,
Rosanna
