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 provides financial planning services, not only portfolio management.
  • 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. Ask whether the firm acts as a fiduciary for all of your accounts, how it is paid in total, and who holds your assets. Our guide to choosing a financial adviser lists the questions to ask.
