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 not high-net-worth, so it is likely to work with people who are still building assets.
• It reports no disciplinary history on Form ADV.

Before you hire any adviser

Read the firm’s Form ADV Part 2 brochure on its SEC record: it sets out fees, minimums, conflicts of interest and who will manage your money.
