Our core strength is long-term wealth planning. We manage client investment portfolios and work with those clients to develop a 360-degree picture of their finances, needs, goals, and plans for retirement.

We are a fiduciary that is required to act in the best interest of our clients. Stock and bond markets go up and down over time, and sometimes those moves can be significant. Clients trust us to manage their portfolios through the up and down cycles in a disciplined and consistent manner. 

We currently offer two investment strategies that serve as a basis for managing client portfolios and can customize those portfolios as needed or desired.

About Our Name

Benjamin Franklin is one of our heroes. Back when Joe was first reading Franklin’s autobiography and learning about his Thirteen Virtues, he noticed that the first letters of virtues two through seven spelled SORFIS, which was both pronounceable and unique—and the origin of the name. And it should be noted that while the six virtues that spell SORFIS are all great traits for someone running an investment firm, the other seven are also plenty beneficial, if not more so, to both building a successful business and a good life.
