Quote from slapshot:
My experience has been the exact opposite. I opened with AMP recently because Mirus would not even follow up on my commission quote request and other questions. I submitted the request twice to no avail and finally wrote in to the VP and on day 3, someone reluctantly tried to contact me.
The rep from AMP, Kevin O'Grady, has been phenomenal in making sure I was set up right, answering technical questions (including telling me he didn't know rather than bluffing and then he researched the answer in 1 hour and called me until he got through and helped me.)
So far, AMP has been the best service of any trading company I have dealt with - period.
Of particular note, it has been the proactive follow up on their part that has seriously impressed me.
I clear with Dorman through them, probably as safe as it gets.
Plus, as a bonus, their per side was .20 less
