Who We Are


Based in the Detroit suburb of Farmington Hills, GPM is an independent, employee-owned portfolio management and advisory firm founded in 1993 by Timothy Griffin.


Tim leads the research and portfolio management efforts of a well-focused team with more than seventy years of combined experience managing money for and advising a diverse base of private clients.


Our client stock and balanced portfolios are actively managed and built on a solid foundation of approximately 30 high-quality, U.S. based,  sustainable growth companies that compete and win worldwide.

We invest in high quality, U.S. based sustainable growth companies that compete and win worldwide.  

Our stock investment process is executed with discipline and consistency. We invest in high quality companies that we believe can over time, provide attractive returns with less risk than the overall market.  

We focus on three core criteria:

  • A highly sustainable business that we understand, led by an agile management team with a long-term record of rewarding growth in sales, earnings, cash flow, dividends, and ultimately stock prices.
  • Product innovation and service superiority that enables demand creation and positions the company to compete and win worldwide.
  • Business visibility that supports reasonable forecasting.

Client portfolios are actively managed with a long-term perspective to deliver growth and income.  We normally own shares of approximately 30 companies.  

  • Stock accounts are normally 100% invested for long-term growth in value and income.
  • Balanced accounts take a more conservative, moderate risk approach and hold stocks and bonds.

GPM’s collaborative wealth management and guidance is exceptionally well-tailored to each client and supported with a strong technology platform.  We routinely engage with client tax advisors and attorneys to assist in tax, estate and generational wealth planning and to help structure funding of their philanthropic pursuits.
