I know Rob Chappell from outside my Merrill Lynch relationship. I trust him completely as I've known Rob to be one of the most ethical people I've ever met. Rob has assembled a team that really checked the box for me. When I went searching for financial advisors, I wanted someone that was a CFP at a minimum. Rob's team, particularly my advisor, has a CFA and has also passed all of the actuarial exams. Rob's team has every designation I could want. Furthermore, Rob himself has not taken on a new client in over 20 years. This tells me that his clients stay with him.
As far as whether I've been pleased with them, it's still too early to tell, but my experience thus far has been very positive. Not sure what the teams' financial thresholds are, but I do have assets greater than $1,000,000, but I only turned over about a quarter of that to Rob's team. They were very upfront with me. They told me that they'd never advise me to make a move that would be detrimental to my own portfolio. For example, they could have tried to move my Fidelity 401k over to Merrill Lynch, but refused it because they could not compete on the fees.
I asked them how they intended to make money off of my account. Their response was that they take a very long term view of their clients and said they'd hope to manage more of my assets once I was retired, etc.
