What this means for you
- It offers hourly or fixed-fee arrangements, so you may be able to pay for a plan without handing over your investments.
- It also charges a percentage of assets managed for ongoing investment management.
- Most of its individual clients are high-net-worth, which on Form ADV means they meet the SEC’s qualified-client or qualified-purchaser test: broadly, more than $1 million managed by the adviser or a net worth above $2 million, with the thresholds indexed for inflation.
- It provides financial planning services, not only portfolio management.
- It reports no disciplinary history on Form ADV.
