John Per O’Sullivan
Managing Director, Partner
John (J.P.) O’Sullivan serves as the Managing Director at Per Stirling. Additionally, he is the lead manager for the Per Stirling Conservative Growth and Core Growth portfolios. In 2009, Mr. O’Sullivan co-founded Per Stirling with his partner, Robert Phipps, with the goal of creating a firm focused on bringing fiduciary standards to the advisor/client relationship.
Before co-founding Per Stirling, Mr. O’Sullivan served as a global macro hedge fund manager with CACH Capital Management and, prior to that, President of one of the largest financial services firms headquartered in central Texas, Choice Asset Management.
Previously, Mr. O’Sullivan also served as the Chief Investment Officer for Lucien, Stirling and Gray. Mr. O’Sullivan is a graduate from the University of Texas at Austin with a degree in Business Economics and post graduate course work in applied statistics.
In addition to the company-sponsored portfolios that he manages for Per Stirling, Mr. O’Sullivan manages money for a select group of individual, corporate and non-profit organizations. Many of these individual clients are business owners in the Austin-area or entrepreneurs who have successfully sold their businesses, and who thus require individualized planning, portfolio design and management.
J.P. believes that building a great investment portfolio is very similar to managing a successful baseball team. ‘As in baseball, having one or two great positions in a portfolio doesn’t lead to success. Success is the result of careful selection at every position, understanding how each of those positions work in relation to one another, and being prepared to make changes in the lineup as conditions warrant. When this process is done well, an investment portfolio is actually greater than the sum of its individual parts, which allows for long-term success for our clients.’
John lives in North Austin with his wife Monica and their three children. He stays physically active with early morning workouts and if the weekend weather is good, you will likely find him outside on the volleyball court, or baseball field with his family. J.P. has previously served as a board member for the non-profit organization Hope for Orphans and currently volunteer coaches youth sports with the Texas Senators baseball organization.
