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 reports no disciplinary history on Form ADV.
