Our History

Petersen, Flynn & Dinsmore, Inc. was established in 1978 to fill the need for a client-focused, professional investment management firm where individual clients were not lost in the shuffle.

In 2015, we changed our name to Cornerstone Capital, Inc. to better reflect the firm's current structure. A Cornerstone has long been the symbol of a solid foundation. We have chosen this name as we believe it accurately conveys our intent to provide clients with a sound, fundamental base for their financial future in an environment that emphasizes close, service-oriented relationships. Each client at Cornerstone Capital has a custom-built portfolio based upon their specific goals and objectives.

With the name change our ownership structure remains the same - Brad Dinsmore, Mason Ford and Brad Branson are each one-third owners of the firm.
