Typically it’s one CSA to 1-1.5mm of production. So in the office I was at, each CSA worked with 1-3 advisors, depending on the size of the advisor’s book.They answer the phones, set up the accounts, do paperwork, assist with servicing the clients. (checkbooks, withdrawals, etc). They do NOT make recommendations or typically do any type of review or advisory work. A Registered associate can place trades for the advisors. Non registered csa’s cannot place trades or take trade requests on the phone. Neither csa’s nor registered csa’s would typically do any selling but they do stuff envelopes, make calls, etc.

At the firm i was at they had 6 weeks vacation, 2 weeks sick time, and rarely worked more than 30 hours in a salaried week. They get sweet bonuses from their advisors and make as much as many small book FA’s. Not a bad gig, but a lot depends on if your FAs are decent people or not.
