We believe the investment landscape consistently provides opportunities for our clients to profit.

Frontenac Partners is an investment firm offering institutional-quality investment management services to the individual investor. We have a limited number of clients whom we are able to serve with a high level of personal contact. Because of our size, we can provide an extra degree of customization to individual portfolios that larger managers fail to provide.

Our three person team exclusively provides all the investment management, analytical, and client communication services. We are dedicated to minimizing investment management fees: we do not employ multiple layers of investment planners, distributors, and third party funds all of whom typically levy hidden fees.

To keep our expenses low we partner with Charles Schwab to facilitate our administrative processes. Schwab is the industry leader in assisting independent asset managers. We value the high quality of their service, and so do our clients.

We founded Frontenac Partners to help individual investors achieve their investment goals.

Our principals and founders, Fred Quirsfeld and Brad Stone, have been in the investment business for over 70 years, cumulatively. Peter Quirsfeld recently joined our firm as an associate.

We have managed investments for a broad range of clients over the course of our careers including individuals, pension funds, mutual funds, insurance companies, municipalities, and banks.
